without warranty of any kind.
Basic Installation
==================
Briefly, the shell commands `./configure; make; make install' should
configure, build, and install this package. The following
more-detailed instructions are generic; see the `README' file for
instructions specific to this package. Some packages provide this
`INSTALL' file but do not implement all of the features documented
below. The lack of an optional feature in a given package is not
necessarily a bug. More recommendations for GNU packages can be found
in *note Makefile Conventions: (standards)Makefile Conventions.
The `configure' shell script attempts to guess correct values for
various system-dependent variables used during compilation. It uses
those values to create a `Makefile' in each directory of the package.
It may also create one or more `.h' files containing system-dependent
definitions. Finally, it creates a shell script `config.status' that
you can run in the future to recreate the current configuration, and a
file `config.log' containing compiler output (useful mainly for
debugging `configure').
It can also use an optional file (typically called `config.cache'
and enabled with `--cache-file=config.cache' or simply `-C') that saves
the results of its tests to speed up reconfiguring. Caching is
disabled by default to prevent problems with accidental use of stale
cache files.
If you need to do unusual things to compile the package, please try
to figure out how `configure' could check whether to do them, and mail
diffs or instructions to the address given in the `README' so they can
be considered for the next release. If you are using the cache, and at
some point `config.cache' contains results you don't want to keep, you
may remove or edit it.
The file `configure.ac' (or `configure.in') is used to create
`configure' by a program called `autoconf'. You need `configure.ac' if
you want to change it or regenerate `configure' using a newer version
of `autoconf'.
The simplest way to compile this package is:
1. `cd' to the directory containing the package's source code and type
`./configure' to configure the package for your system.
Running `configure' might take a while. While running, it prints
some messages telling which features it is checking for.
2. Type `make' to compile the package.
3. Optionally, type `make check' to run any self-tests that come with
the package, generally using the just-built uninstalled binaries.
4. Type `make install' to install the programs and any data files and
documentation. When installing into a prefix owned by root, it is
recommended that the package be configured and built as a regular
user, and only the `make install' phase executed with root
privileges.
5. Optionally, type `make installcheck' to repeat any self-tests, but
this time using the binaries in their final installed location.
This target does not install anything. Running this target as a
regular user, particularly if the prior `make install' required
root privileges, verifies that the installation completed
correctly.
6. You can remove the program binaries and object files from the
source code directory by typing `make clean'. To also remove the
files that `configure' created (so you can compile the package for
a different kind of computer), type `make distclean'. There is
also a `make maintainer-clean' target, but that is intended mainly
for the package's developers. If you use it, you may have to get
all sorts of other programs in order to regenerate files that came
with the distribution.
7. Often, you can also type `make uninstall' to remove the installed
files again. In practice, not all packages have tested that
uninstallation works correctly, even though it is required by the
GNU Coding Standards.
8. Some packages, particularly those that use Automake, provide `make
distcheck', which can by used by developers to test that all other
targets like `make install' and `make uninstall' work correctly.
This target is generally not run by end users.
Compilers and Options
=====================
Some systems require unusual options for compilation or linking that
the `configure' script does not know about. Run `./configure --help'
for details on some of the pertinent environment variables.
You can give `configure' initial values for configuration parameters
by setting variables in the command line or in the environment. Here
is an example:
./configure CC=c99 CFLAGS=-g LIBS=-lposix
*Note Defining Variables::, for more details.
Compiling For Multiple Architectures
====================================
You can compile the package for more than one kind of computer at the
same time, by placing the object files for each architecture in their
own directory. To do this, you can use GNU `make'. `cd' to the
directory where you want the object files and executables to go and run
the `configure' script. `configure' automatically checks for the
source code in the directory that `configure' is in and in `..'. This
is known as a "VPATH" build.
With a non-GNU `make', it is safer to compile the package for one
architecture at a time in the source code directory. After you have
installed the package for one architecture, use `make distclean' before
reconfiguring for another architecture.
On MacOS X 10.5 and later systems, you can create libraries and
executables that work on multiple system types--known as "fat" or
"universal" binaries--by specifying multiple `-arch' options to the
compiler but only a single `-arch' option to the preprocessor. Like
this:
./configure CC="gcc -arch i386 -arch x86_64 -arch ppc -arch ppc64" \
CXX="g++ -arch i386 -arch x86_64 -arch ppc -arch ppc64" \
CPP="gcc -E" CXXCPP="g++ -E"
This is not guaranteed to produce working output in all cases, you
may have to build one architecture at a time and combine the results
using the `lipo' tool if you have problems.
Installation Names
==================
By default, `make install' installs the package's commands under
`/usr/local/bin', include files under `/usr/local/include', etc. You
can specify an installation prefix other than `/usr/local' by giving
`configure' the option `--prefix=PREFIX', where PREFIX must be an
absolute file name.
You can specify separate installation prefixes for
architecture-specific files and architecture-independent files. If you
pass the option `--exec-prefix=PREFIX' to `configure', the package uses
PREFIX as the prefix for installing programs and libraries.
Documentation and other data files still use the regular prefix.
In addition, if you use an unusual directory layout you can give
options like `--bindir=DIR' to specify different values for particular
kinds of files. Run `configure --help' for a list of the directories
you can set and what kinds of files go in them. In general, the
default for these options is expressed in terms of `${prefix}', so that
specifying just `--prefix' will affect all of the other directory
specifications that were not explicitly provided.
The most portable way to affect installation locations is to pass the
correct locations to `configure'; however, many packages provide one or
both of the following shortcuts of passing variable assignments to the
`make install' command line to change installation locations without
having to reconfigure or recompile.
The first method involves providing an override variable for each
affected directory. For example, `make install
prefix=/alternate/directory' will choose an alternate location for all
directory configuration variables that were expressed in terms of
`${prefix}'. Any directories that were specified during `configure',
but not in terms of `${prefix}', must each be overridden at install
time for the entire installation to be relocated. The approach of
makefile variable overrides for each directory variable is required by
the GNU Coding Standards, and ideally causes no recompilation.
However, some platforms have known limitations with the semantics of
shared libraries that end up requiring recompilation when using this
method, particularly noticeable in packages that use GNU Libtool.
The second method involves providing the `DESTDIR' variable. For
example, `make install DESTDIR=/alternate/directory' will prepend
`/alternate/directory' before all installation names. The approach of
`DESTDIR' overrides is not required by the GNU Coding Standards, and
does not work on platforms that have drive letters. On the other hand,
it does better at avoiding recompilation issues, and works well even
when some directory options were not specified in terms of `${prefix}'
at `configure' time.
Optional Features
=================
If the package supports it, you can cause programs to be installed
with an extra prefix or suffix on their names by giving `configure' the
option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
Some packages pay attention to `--enable-FEATURE' options to
`configure', where FEATURE indicates an optional part of the package.
They may also pay attention to `--with-PACKAGE' options, where PACKAGE
is something like `gnu-as' or `x' (for the X Window System). The
`README' should mention any `--enable-' and `--with-' options that the
package recognizes.
For packages that use the X Window System, `configure' can usually
find the X include and library files automatically, but if it doesn't,
you can use the `configure' options `--x-includes=DIR' and
`--x-libraries=DIR' to specify their locations.
Some packages offer the ability to configure how verbose the
execution of `make' will be. For these packages, running `./configure
--enable-silent-rules' sets the default to minimal output, which can be
overridden with `make V=1'; while running `./configure
--disable-silent-rules' sets the default to verbose, which can be
overridden with `make V=0'.
Particular systems
==================
On HP-UX, the default C compiler is not ANSI C compatible. If GNU
CC is not installed, it is recommended to use the following options in
order to use an ANSI C compiler:
./configure CC="cc -Ae -D_XOPEN_SOURCE=500"
and if that doesn't work, install pre-built binaries of GCC for HP-UX.
On OSF/1 a.k.a. Tru64, some versions of the default C compiler cannot
parse its `<wchar.h>' header file. The option `-nodtk' can be used as
a workaround. If GNU CC is not installed, it is therefore recommended
to try
./configure CC="cc"
and if that doesn't work, try
./configure CC="cc -nodtk"
On Solaris, don't put `/usr/ucb' early in your `PATH'. This
directory contains several dysfunctional programs; working variants of
these programs are available in `/usr/bin'. So, if you need `/usr/ucb'
in your `PATH', put it _after_ `/usr/bin'.
On Haiku, software installed for all users goes in `/boot/common',
not `/usr/local'. It is recommended to use the following options:
./configure --prefix=/boot/common
Specifying the System Type
==========================
There may be some features `configure' cannot figure out
automatically, but needs to determine by the type of machine the package
will run on. Usually, assuming the package is built to be run on the
_same_ architectures, `configure' can figure that out, but if it prints
a message saying it cannot guess the machine type, give it the
`--build=TYPE' option. TYPE can either be a short name for the system
type, such as `sun4', or a canonical name which has the form:
CPU-COMPANY-SYSTEM
where SYSTEM can have one of these forms:
OS
KERNEL-OS
See the file `config.sub' for the possible values of each field. If
`config.sub' isn't included in this package, then this package doesn't
need to know the machine type.
If you are _building_ compiler tools for cross-compiling, you should
use the option `--target=TYPE' to select the type of system they will
produce code for.
If you want to _use_ a cross compiler, that generates code for a
platform different from the build platform, you should specify the
"host" platform (i.e., that on which the generated programs will
eventually be run) with `--host=TYPE'.
Sharing Defaults
================
If you want to set default values for `configure' scripts to share,
you can create a site shell script called `config.site' that gives
default values for variables like `CC', `cache_file', and `prefix'.
`configure' looks for `PREFIX/share/config.site' if it exists, then
`PREFIX/etc/config.site' if it exists. Or, you can set the
`CONFIG_SITE' environment variable to the location of the site script.
A warning: not all `configure' scripts look for a site script.
Defining Variables
==================
Variables not defined in a site shell script can be set in the
environment passed to `configure'. However, some packages may run
configure again during the build, and the customized values of these
variables may be lost. In order to avoid this problem, you should set
them in the `configure' command line, using `VAR=value'. For example:
./configure CC=/usr/local2/bin/gcc
causes the specified `gcc' to be used as the C compiler (unless it is
overridden in the site shell script).
Unfortunately, this technique does not work for `CONFIG_SHELL' due to
an Autoconf bug. Until the bug is fixed you can use this workaround:
CONFIG_SHELL=/bin/bash /bin/bash ./configure CONFIG_SHELL=/bin/bash
`configure' Invocation
======================
`configure' recognizes the following options to control how it
operates.
`--help'
`-h'
Print a summary of all of the options to `configure', and exit.
`--help=short'
`--help=recursive'
Print a summary of the options unique to this package's
`configure', and exit. The `short' variant lists options used
only in the top level, while the `recursive' variant lists options
also present in any nested packages.
`--version'
`-V'
Print the version of Autoconf used to generate the `configure'
script, and exit.
`--cache-file=FILE'
Enable the cache: use and save the results of the tests in FILE,
traditionally `config.cache'. FILE defaults to `/dev/null' to
disable caching.
`--config-cache'
`-C'
Alias for `--cache-file=config.cache'.
`--quiet'
`--silent'
`-q'
Do not print messages saying which checks are being made. To
suppress all normal output, redirect it to `/dev/null' (any error
messages will still be shown).
`--srcdir=DIR'
Look for the package's source code in directory DIR. Usually
`configure' can determine that directory automatically.
`--prefix=DIR'
Use DIR as the installation prefix. *note Installation Names::
for more details, including other options available for fine-tuning
the installation locations.
`--no-create'
`-n'
Run the configure checks, but stop before creating any output
files.
`configure' also accepts some other, not widely useful, options. Run
`configure --help' for more details.

[![Build Status](https://api.travis-ci.org/FFMS/ffms2.svg?branch=master)](https://travis-ci.org/FFMS/ffms2)
**FFmpegSource** (usually known as **FFMS** or **FFMS2**) is a cross-platform wrapper library around [FFmpeg](http://ffmpeg.org). It gives you an easy, convenient way to say "open and decompress this media file for me, I don't care how you do it" and get frame- and sample-accurate access (usually), without having to bother with the sometimes less than straightforward and less than perfectly documented FFmpeg API.
The library is written in C++, but the public API is pure C, so if you can link to a C library, you can use FFMS2. The source is available under the MIT license, but the license of the binaries depends on how FFmpeg was compiled. There are optional components that require a GPL FFmpeg, and if those are compiled in FFMS2 itself becomes covered by the GPL as well. The official Windows builds are GPLv3 for this reason.
For more information on using the library, see the [API documentation](doc/ffms2-api.md) and the [changelog](doc/ffms2-changelog.md).
### Avisynth and VapourSynth plugin
For the end user, the most visible use of FFMS is the implementation of both an [Avisynth](http://avisynth.nl) and a [VapourSynth](http://www.vapoursynth.com) source plugin that uses the FFMS library to open media files. This plugin is a part of the FFMS2 project and is available for download here; for documentation see the [Avisynth user guide](doc/ffms2-avisynth.md).
### Features
In addition to being able to open almost any common audio or video format, the Avisynth plugin has a number of more or less unique properties that other Avisynth source filters lack:
* It is the only source filter that has support for Unicode filenames that are not representable in the system codepage.
* It is the only source filter that has proper variable framerate (VFR) support.
* It is the only general-purpose (i.e. not restricted to one or a few formats) source filter that will work reliably when running Avisynth under Wine.
* It is the only general-purpose source filter that does not rely on external decoders.
* It is (probably) the only source filter that supports mid-stream video resolution switches.
### Versions and variants
If you're confused by all the different variants, here's a small explanation:
* Vanilla (no suffix): standard 32-bit version. If you don't know what you want, you want this.
* -x64: 64-bit version; mostly for use with 64-bit Avisynth.
* -avs-cplugin: Variant of the Avisynth plugin written in C. Primary purpose is to get access to the new colorspaces available in Avisynth 2.6.
* SDK: software developer's kit, for people who want to develop Windows applications that use FFMS2, using Microsoft Visual Studio 2008 or later.
Packages marked rNUMBER are testing builds made in-between releases. Download them if you need some bleeding-edge feature or just want to test out the upcoming version. Do note that they may be less stable than the official release versions.
### Why is it called FFmpegSource, that makes no sense at all!?!
FFMS originated as an Avisynth file reader plugin, and those are traditionally called FooSource, where Foo usually is the method used to open the file. For historical reasons the entire project is still called FFmpegSource, although these days the name is pretty misleading and makes people think it has something to do with FFmpeg's source code or somesuch. To avoid confusion, it's probably better to refer to the library as FFMS (2, since version 1 was only an Avisynth plugin...) and keep the FFmpegSource name for the Avisynth plugin.

## (see the conditional assignment to $gccflag above).
## There are various ways to get dependency output from gcc. Here's
## why we pick this rather obscure method:
## - Don't want to use -MD because we'd like the dependencies to end
## up in a subdir. Having to rename by hand is ugly.
## (We might end up doing this anyway to support other compilers.)
## - The DEPENDENCIES_OUTPUT environment variable makes gcc act like
## -MM, not -M (despite what the docs say). Also, it might not be
## supported by the other compilers which use the 'gcc' depmode.
## - Using -M directly means running the compiler twice (even worse
## than renaming).

## This next piece of magic avoids the "deleted header file" problem.
## The problem is that when a header file which appears in a .P file
## is deleted, the dependency causes make to die (because there is
## typically no way to rebuild the header). We avoid this by adding
## dummy dependencies for each header file. Too bad gcc doesn't do
## this for us directly.
## Some versions of gcc put a space before the ':'. On the theory
## that the space means something, we add a space to the output as
## well. hp depmode also adds that space, but also prefixes the VPATH
## to the object. Take care to not repeat it in the output.
## Some versions of the HPUX 10.20 sed can't process this invocation
## correctly. Breaking it into two sed invocations is a workaround.

# FFmpegSource2 Avisynth User Manual
Opens files using FFmpeg and nothing else.
May be frame accurate on good days.
The source is MIT licensed and can be obtained from https://github.com/FFMS/ffms2/.
The precompiled binary is GPL3 licensed.
If you are religious you may consider this the second coming.

[![Donate](https://www.paypalobjects.com/en_US/i/btn/btn_donate_LG.gif)](https://www.paypal.com/cgi-bin/webscr?cmd=_donations&business=fredrik%2emellbin%40gmail%2ecom&lc=US&item_name=IVTC%2eORG&no_note=0&currency_code=USD&bn=PP%2dDonationsBF%3abtn_donate_LG%2egif%3aNonHostedGuest)
## Limitations
- Because of LAVF's demuxer, most raw streams (such as elementary h264 and other mpeg video streams) will fail to work properly.
- FFAudioSource() will have to remake any index implicitly created by FFVideoSource() and therefore code like
```
AudioDub(FFVideoSource(X), FFAudioSource(X))
```
will require two indexing passes. Apart from the time consumed this is harmless.
To work around it open the audio first:
```
A = FFAudioSource(X)
V = FFVideoSource(X)
AudioDub(V, A)
```
or use FFIndex(), like so:
```
FFIndex(X)
AudioDub(FFVideoSource(X), FFAudioSource(X))
```
- Interlaced H.264 mostly works these days, but seeking may occasionally result in corruption.
- Transport Streams will not decode reliably without seekmode -1.
- Open-GOP H.264 will sometimes produces corruption when seeking.
## Compatibility
### Video
- AVI, MKV, MP4, FLV: Frame accurate
- WMV: Frame accurate(?) but avformat seems to pick keyframes relatively far away
- OGM: Frame accurate(?)
- VOB, MPG: Seeking seems to be off by one or two frames now and then
- M2TS, TS: Seeking seems to be off a few frames here and there
- Image files: Most formats can be opened if seekmode=-1 is set, no animation support
### Audio
Seeking should be sample-accurate with most codecs in AVI, MKV, MP4 and FLV.
Decoding linearly will almost always give correct results, and forward-seeks from trimming should result in at most a few hundred samples of corruption.
## Indexing and You
Before FFMS2 can open a file, it must be indexed first so that keyframe/sample positions are known and seeking is easily accomplished.
This is done automatically when using `FFVideoSource()` or `FFAudioSource()`,
but if you want to you can invoke the indexing yourself by calling `FFIndex()`, or by running `ffmsindex.exe`.
By default the index is written to a file so it can be reused the next time you open the same file, but this behavior can be turned off if desired.
If you wonder why FFMS2 takes so long opening files, the indexing is the answer.
If you want a progress report on the indexing, you can use the supplied `ffmsindex.exe` commandline program.
## Function reference
### FFIndex
```
FFIndex(string source, string cachefile = source + ".ffindex", int indexmask = -1,
int errorhandling = 3, bool overwrite = false)
```
Indexes a number of tracks in a given source file and writes the index file to disk, where it can be picked up and used by `FFVideoSource` or `FFAudioSource`.
Normally you do not need to call this function manually; it's invoked automatically if necessary by `FFVideoSource`/`FFAudioSource`.
It does, however, give you more control over how indexing is done.
Note that this function returns an integer, not a clip (since it doesn't open video, nor audio).
The return value isn't particularly interesting, but for the record it's 0 if the index file already exists (and is valid) and overwrite was not enabled, 1 if the index file was created and no previous index existed, and 2 if the index file was created by overwriting an existing, valid index file.
#### Arguments
##### string source
The source file to index.
##### string cachefile = source + ".ffindex"
The filename of the index file (where the indexing data is saved).
Defaults to `sourcefilename.ffindex`.
##### int indexmask = -1
A binary mask representing what audio tracks should be indexed (all video tracks are always indexed; you have no choice in the matter).
The mask is constructed by bitshifting 1 left by the track number; if multiple tracks are desired, bitwise OR each value so created together to get the full mask.
In other words, the mask is a bit field where each bit is a track number (the least significant bit is track number 0).
Since Avisynth doesn't have any bitwise operators at all, constructing a mask for more than one track inside an Avisynth script is a rather annoying task; for a single track the mask is, naturally, 2 to the power of the track number minus 1 (i.e. if you want to index track 3, the mask is `2^(3-1) = 4`).
Since the mask works like it does, and FFMS2 is designed to run on a machine that uses two's complement integers, -1 (the default) means index all tracks and 0 means index none.
Note that FFMS2's idea about what track has what number may be completely different from what any other application might think, and that track numbering starts from 1.
##### int errorhandling = 3
Controls what happens if an audio decoding error is encountered during indexing.
Possible values are:
- **0**: Raise an error and abort indexing. No index file is written.
- **1**: Clear the affected track (effectively making it silent) and continue.
- **2**: Stop indexing the track but keep all the index entries so far, effectively ending the track where the error occured.
- **3**: Pretend it's raining and continue anyway. This is the default; if you encounter odd noises in the audio, try mode 0 instead and see if it's FFMS2's fault.
##### bool overwrite = false
If set to true, `FFIndex()` will reindex the source file and overwrite the index file even if the index file already exists and is valid.
Mostly useful for trackmask changes and testing.
### FFVideoSource
```
FFVideoSource(string source, int track = -1, bool cache = true,
string cachefile = source + ".ffindex", int fpsnum = -1, int fpsden = 1,
int threads = -1, string timecodes = "", int seekmode = 1, int rffmode = 0,
int width = -1, int height = -1, string resizer = "BICUBIC",
string colorspace = "", string varprefix = "")
```
Opens video. Will invoke indexing of all video tracks (but no audio tracks) if no valid index file is found.
#### Arguments
##### string source
The source file to open.
##### int track = -1
The video track number to open, as seen by the relevant demuxer.
Track numbers start from zero, and are guaranteed to be continous (i.e. there must be a track 1 if there is a track 0 and a track 2). -1 means open the first video track.
Note that FFMS2's idea about what track has what number may (or may not) be completely different from what some other application might think.
Trying to open an audio track with `FFVideoSource` will naturally fail.
##### bool cache = true
If set to true (the default), `FFVideoSource` will first check if the `cachefile` contains a valid index, and if it does, that index will be used.
If no index is found, all video tracks will be indexed, and the indexing data will be written to `cachefile` afterwards.
If set to false, `FFVideoSource` will not look for an existing index file; instead all video tracks will be indexed when the script is opened, and the indexing data will be discarded after the script is closed; you will have to index again next time you open the script.
##### string cachefile = source + ".ffindex"
The filename of the index file (where the indexing data is saved).
Defaults to `sourcefilename.ffindex`.
Note that if you didn't change this parameter from its default value and `FFVideoSource` encounters an index file that doesn't seem to match the file it's trying to open, it will automatically reindex and then overwrite the old index file.
On the other hand, if you *do* change it, `FFVideoSource` will assume you have your reasons and throw an error instead if the index doesn't match the file.
##### int fpsnum = -1, int fpsden = 1
Controls the framerate of the output; used for VFR to CFR conversions.
If `fpsnum` is less than or equal to zero (the default), the output will contain the same frames that the input did, and the frame rate reported to Avisynth will be set based on the input clip's average frame duration.
If `fpsnum` is greater than zero, `FFVideoSource` will force a constant frame rate, expressed as a rational number where `fpsnum` is the numerator and `fpsden` is the denominator.
This may naturally cause `FFVideoSource` to drop or duplicate frames to achieve the desired frame rate, and the output is not guaranteed to have the same number of frames that the input did.
##### int threads = -1
The number of decoding threads to request from libavcodec.
Setting it to less than or equal to zero means it defaults to the number of logical CPU's reported by Windows.
Note that this setting might be completely ignored by libavcodec under a number of conditions; most commonly because a lot of decoders actually do not support multithreading.
##### string timecodes = ""
Filename to write Matroska v2 timecodes for the opened video track to.
If the file exists, it will be truncated and overwritten.
Set to the empty string to disable timecodes writing (this is the default).
##### int seekmode = 1
Controls how seeking is done.
Mostly useful for getting uncooperative files to work.
Valid modes are:
- **-1**: Linear access without rewind; i.e. will throw an error if each successive requested frame number isn't bigger than the last one.
Only intended for opening images but might work on well with some obscure video format.
- **0**: Linear access (i.e. if you request frame `n` without having requested all frames from 0 to `n-1` in order first, all frames from 0 to `n` will have to be decoded before `n` can be delivered).
The definition of slow, but should make some formats "usable".
- **1**: Safe normal. Bases seeking decisions on the keyframe positions reported by libavformat.
- **2**: Unsafe normal. Same as mode 1, but no error will be thrown if the exact seek destination has to be guessed.
- **3**: Aggressive. Seeks in the forward direction even if no closer keyframe is known to exist. Only useful for testing and containers where libavformat doesn't report keyframes properly.
##### int rffmode = 0
Controls how RFF flags in the video stream are treated; in other words it's equivalent to the "field operation" mode switch in DVD2AVI/DGIndex.
Valid modes are:
- **0**: Ignore all flags (the default mode).
- **1**: Honor all pulldown flags.
- **2**: Equivalent to DVD2AVI's "force film" mode.
Note that using modes 1 or 2 will make `FFVideoSource` throw an error if the video stream has no RFF flags at all.
When using either of those modes, it will also make the output be assumed as CFR, disallow vertical scaling and disallow setting the output colorspace.
`FFPICT_TYPE` will also not be set as the output is a combination of several frames.
Other subtle behavior changes may also exist.
Also note that "force film" is mostly useless and only here for completeness' sake, since if your source really is safe to force film on, using mode 0 will have the exact same effect while being considerably more efficient.
##### int width = -1, int height = -1
Sets the resolution of the output video, in pixels.
Setting either dimension to less than or equal to zero means the resolution of the first decoded video frame is used for that dimension.
These parameters are mostly useful because FFMS2 supports video streams that change resolution mid-stream; since Avisynth does not, these parameters are used to set single resolution for the output.
##### string resizer = "BICUBIC"
The resizing algorithm to use if rescaling the image is necessary.
If the video uses subsampled chroma but your chosen output colorspace does not, the chosen resizer will be used to upscale the chroma planes, even if you did not request an image rescaling.
The available choices are `FAST_BILINEAR`, `BILINEAR`, `BICUBIC` (default), `X`, `POINT`, `AREA`, `BICUBLIN`, `GAUSS`, `SINC`, `LANCZOS` and `SPLINE`.
Note that `SPLINE` is completely different from Avisynth's builtin Spline resizers.
##### string colorspace = ""
Convert the output from whatever it was to the given colorspace, which can be one of `YV12`, `YV16`, `YV24`, `Y8`, `YUY2`, `YV411`, `YUV9`, `RGB24` or `RGB32`.
They can also be referred to with the more systematic names of `YUVsssPx`, `YUVAsssPx`, `Yx`, `RGBPx` or `RGBAPx` where `x` is the desired bitdepth and `sss` represents the subsampling. Formats with an `A` also have an alpha channel.
Examples: `YUV420P8`, `RGBAP16`, `Y16`
Setting this to an empty string (the default) means keeping the same colorspace as the input or in case it's not supported it'll be converted to the closest existing match.
##### string varprefix = ""
A string that is added as a prefix to all exported Avisynth variables.
This makes it possible to differentiate between variables from different clips.
For convenience the last used FFMS function in a script sets the global variable `FFVAR_PREFIX` to its own variable prefix so that `FFInfo()` can default to it.
### FFAudioSource
```
FFAudioSource(string source, int track = -1, bool cache = true,
string cachefile = source + ".ffindex", int adjustdelay = -1,
string varprefix = "")
```
Opens audio.
Invokes indexing of all tracks if no valid index file is found, or if the requested track isn't present in the index.
#### Arguments
Are exactly the same as to `FFVideoSource`, with one exception:
##### int adjustdelay = -1
Controls how audio delay is handled, i.e. what happens if the first audio sample in the file doesn't have a timestamp of zero.
The following arguments are valid:
- **-3**: No adjustment is made; the first decodable audio sample becomes the first sample in the output.
- **-2**: Samples are created (with silence) or discarded so that sample 0 in the decoded audio starts at time zero.
- **-1**: Samples are created (with silence) or discarded so that sample 0 in the decoded audio starts at the same time as frame 0 of the first video track. This is the default, and probably what most people want.
- **Any integer >= 0**: Same as -1, but adjust relative to the video track with the given track number instead.
If the provided track number isn't a video track, an error is raised.
-2 obviously does the same thing as -1 if the first video frame of the first video track starts at time zero.
In some containers this will always be the case, in others (most notably 188-byte MPEG TS) it will almost never happen.
### FFmpegSource2/FFMS2
```
FFmpegSource2/FFMS2(string source, int vtrack = -1, int atrack = -2, bool cache = true,
string cachefile = source + ".ffindex", int fpsnum = -1, int fpsden = 1,
int threads = -1, string timecodes = "", int seekmode = 1,
bool overwrite = false, int width = -1, int height = -1,
string resizer = "BICUBIC", string colorspace = "", int rffmode = 0,
int adjustdelay = -1, string varprefix = "")
```
A convenience function that combines the functionality of `FFVideoSource` and `FFAudioSource`.
The arguments do the same thing as in `FFVideoSource` and `FFAudioSource`; see those functions for details.
`vtrack` and `atrack` are the video and audio track to open, respectively; setting `atrack` <= -2 means audio is disabled.
**Note:** the shorter FFMS2 alias was added in 2.22
### FFImageSource
```
FFImageSource(string source, int width = -1, int height = -1,
string resizer = "BICUBIC", string colorspace = "")
```
A convenience alias for `FFVideoSource`, with the options set optimally for using it as an image reader.
Disables caching and seeking for maximum compatiblity.
### FFInfo
```
FFInfo(clip c, bool framenum = true, bool frametype = true, bool cfrtime = true,
bool vfrtime = true, string varprefix = "", bool colorspace = true,
bool colorrange = true, bool cropping = true, bool sar =true, bool version = true,
bool showprefix = false)
```
A helper function similar to Avisynth's internal `Info()` function; shows general information about the current frame.
Note that not all values are exported in all source modes, so some information may not always be shown.
The arguments can be used to disable the drawing of certain information if so desired.
Use the varprefix argument to determine which clip you want information about.
**Note:** this function is provided by `FFMS2.avsi` and is not available unless that script has been imported or autoloaded.
### FFFormatTime
FFFormatTime(int ms)
A helper function used to format a time given in milliseconds into a h:mm:ss.ttt string.
Used internally by `FFInfo`.
**Note:** this function is provided by `FFMS2.avsi` and is not available unless that script has been imported or autoloaded.
### FFColorSpace
FFColorSpace(int i)
A helper function used to convert a colorspace number into a human readable string.
Used internally by `FFInfo`.
**Note:** this function is provided by `FFMS2.avsi` and is not available unless that script has been imported or autoloaded.
### FFColorRange
FFColorRange(int i)
A helper function used to convert a color range number into a human readable string.
Used internally by `FFInfo`.
**Note:** this function is provided by `FFMS2.avsi` and is not available unless that script has been imported or autoloaded.
### FFCropping
FFCropping(int l, int t, int r, int b)
A helper function used to convert cropping information into a human readable string.
Used internally by `FFInfo`.
**Note:** this function is provided by `FFMS2.avsi` and is not available unless that script has been imported or autoloaded.
### FFSampAR
FFSampAR(int num,int den)
A helper function used to convert the sample aspect ratio into a human readable string.
Used internally by `FFInfo`.
**Note:** this function is provided by `FFMS2.avsi` and is not available unless that script has been imported or autoloaded.
### FFPictType
FFPictType(int ch)
A helper function used to convert a picture type character into a human readable string.
Used internally by `FFInfo`.
**Note:** this function is provided by `FFMS2.avsi` and is not available unless that script has been imported or autoloaded.
### FFSetLogLevel
```
FFSetLogLevel(int Level = -8)
```
Sets the FFmpeg logging level, i.e. how much diagnostic spam it prints to STDERR.
Since most applications that open Avisynth scripts do not provide a way to display things printed to STDERR, and since it's rather hard to make any sense of the printed messages unless you're quite familiar with FFmpeg internals, the usefulness of this function is rather limited for end users. It's mostly intended for debugging.
Defaults to quiet (no messages printed); a list of meaningful values can be found in `ffms.h`.
### FFGetLogLevel
```
FFGetLogLevel()
```
Returns the current log level, as an integer.
### FFGetVersion
```
FFGetVersion()
```
Returns the FFMS2 version, as a string.
## Exported Avisynth variables
All variable names are prefixed by the `varprefix` argument to the respective `FFVideoSource` or `FFAudioSource` call that generated them.
##### FFSAR_NUM, FFSAR_DEN, FFSAR
The playback aspect ratio specified by the container.
`FFSAR_NUM` and `FFSAR_DEN` make up the rational number of the ratio; `FFSAR` is only provided for convenience and may not be set in case it cannot be calculated (i.e. if `FFSAR_DEN` is zero).
##### FFCROP_LEFT, FFCROP_RIGHT, FFCROP_TOP, FFCROP_BOTTOM
The on-playback cropping specified by the container.
##### FFCOLOR_SPACE
The colorimetry the input claims to be using. Only meaningful for YUV inputs.
The source for this variable is a metadata flag that can arbitrarily be set or manipulated at will by incompetent users or buggy programs without changing the actual video content, so blindly trusting its correctness is not recommended.
The value is exported as a cryptic numerical constant that matches the values in the MPEG-2 specification.
You can find the gory details in the FFMS2 API documentation, but the important ones are:
- **0**: RGB (usually indicates the stream isn't actually YUV, but RGB flagged as YUV)
- **1**: ITU-R Rec.709
- **2**: Unknown or unspecified
- **5 and 6**: ITU-R Rec.601
##### FFCOLOR_RANGE
The color range the input video claims to be using.
Much like FFCOLOR_SPACE, the source for this variable is a metadata flag that can freely be set to arbitrary values, so trusting it blindly might not be a good idea.
Note that using the width/height/colorspace parameters to FFVideoSource may under some circumstances change the output color range.
- **0**: Unknown/unspecified
- **1**: Limited range (usually 16-235)
- **2**: Full range (0-255)
##### FFPICT_TYPE
The picture type of the most recently requested frame as the ASCII number of the character listed below.
Use `Chr()` to convert it to an actual letter in Avisynth. Use after_frame=true in Avisynth's conditional scripting for proper results.
Only set when rffmode=0.
The FFmpeg source definition of the characters:
```
I: Intra
P: Predicted
B: Bi-dir predicted
S: S(GMC)-VOP MPEG4
i: Switching Intra
p: Switching Predicted
b: FF_BI_TYPE (no good explanation available)
?: Unknown
```
##### FFVFR_TIME
The actual time of the source frame in milliseconds.
Only set when no type of CFR conversion is being done (`rffmode` and `fpsnum` left at their defaults).
##### FFCHANNEL_LAYOUT
The audio channel layout of the audio stream.
This is exported as a very cryptic integer that is constructed in the same way as the `dwChannelMask` property of the Windows `WAVEFORMATEXTENSIBLE` struct.
If you don't know what a `WAVEFORMATEXTENSIBLE` is or what the `dwChannelMask` does, don't worry about it.
##### FFVAR_PREFIX
The variable prefix of the last called FFMS source function.
Note that this is a global variable.

- Add support for planar audio from lavc. (Plorkyeran)
- Add SetOutputFormatA for audio resampling/mixing using libavresample. (Plorkyeran)
- Zero-length index files are now rejected rather than bad things happening.
- 2.17
- Reworked color matrix and color range handling a bit, which fixed a bug that could cause FFMS2 to always output TV range even if the input was full range. (TheFluff)
- The autotools build system can now create debug builds properly. (Daemon404)
- Deprecated parts of the API will now cause compiler warnings when you use them. (TheFluff)
- Added a `FFMS_GetVersion` function to the API (lets library users get the version number at runtime) and exposed it in Avisynth as `FFGetVersion`. (TheRyuu, TheFluff)
- Added a variable prefix option to the Avisynth functions. Its primary purpose is to get subsequent calls to source functions from overwriting variables from earlier calls. (TheFluff)
- Make it possible to open single-frame videos without explicitly setting seekmode to -1 for you weird people who want to open images with ffms (Plorkyeran)
- Fixed bug where indices would sometimes be incorrectly considered valid (TheRyuu)
- Add support for recent versions of Libav/FFmpeg built as shared libraries (Plorkyeran, TheRyuu, Kovensky)
- When possible, non-API symbols are no longer exported (Daemon404, TheFluff)
- Deprecate postprocessing support. Libav and FFmpeg are planning on removing it at some point in the near future and it's really not very useful.
- Fix the pkg-config version on OS X (Plorkyeran).
- Fixed a bug that could cause the `FFmpegSource2()` Avisynth function to not use UTF8 filenames even when told to do so. (pandv2)
- Fixed a few minor memory leaks. (Plorkyeran)
- Adjusting audio delay relative to the first video track should now work properly again (was broken in 2.16). (Plorkyeran)
- General bitrot fixes to deal with changes in Libav/FFmpeg (everyone)
- Corrected handling of codec private data when using a non-libavformat parser. Fixes decoding of FFV1 and UTVideo in MKV, among other things. (TheFluff)
- Bump minimum required version of FFmpeg to 0.6.
- 2.16
- Reimplemented output colorspace selection, this should fix all issues with the Avisynth plugin when opening yuv420p10 or yuv444 material plus several other less common cases. (Myrsloik)
- Added `FFMS_SetOutputFormatV2` to the API. This function allows you to specify PixelFormats >= 64 for use as output. (Myrsloik)
- Fixed a serious bug that could cause crashes and completely useless index files with h264 in Matroska. (Myrsloik)
- Automatically detect number of decoding threads. The Avisynth video source funtion already did this, now moved so the API can use it as well. (TheRyuu)
- Re-add the ability to target x64 with MSVC, since it's a bit more sane now. (TheRyuu)
- Fixed a bug that could cause crashes when reading audio if FFMS2 was compiled with GCC. (Myrsloik)
- ffmsindex will no longer crash if it cannot open the file given to it for indexing. (TheFluff)
- FFMS2 will no longer crash if the video decoder feeds it an empty frame (can sometimes happen when using lots of decoder threads); you'll get a nice error message instead. (TheFluff)
- The C-plugin can now act as both an Avisynth 2.6 plugin (including support for new colorspaces) as well as an Avisynth 2.5 one, in the same binary. (kemuri_-9)
- Fixed an issue that could cause opening Vorbis audio to fail because FFMS2 couldn't find an initial valid PTS. (TheFluff)
- FFMS2 will no longer crash if forced or tricked into using an index file generated by a FFMS2 version compiled for a different architecture. (TheRyuu)
- Fixed a crash when the last frame was requested using the Avisynth plugin's forced CFR mode. (Plorkyeran)
- Fixed various issues with decoding audio from the Ogg container without Haali's splitter. (Myrsloik, TheFluff)
- Fixed the "invalid postprocessing settings", it is caused by a parsing bug in libpostproc and a workaround has been added (Myrsloik)
- Tinkered a bit with the non-MSVS build system. (Daemon404, Kovensky)
- 2.15
- FFVideoSource and FFAudioSource will now automatically reindex and overwrite the index file if it doesn't match the file being opened and the `cachefile` argument is left as the default. (Plorkyeran)
- FFMS2 can now be used to decode Lagarith, but note that libavcodec's decoder is very experimental at the moment. (Plorkyeran)
- SWScale can now use SSE2 optimizations for certain operations if your CPU supports it. (kemuri_-9)
- Fixed a bug that could cause SWScale initialization to fail. (kemuri_-9)
- Fixed a bug that could cause index files to never be considered valid, forcing a reindexing every time a script was loaded. (TheRyuu)
- Trying to use postprocessing on a fullrange YUV clip will no longer cause errors. (TheFluff)
- Fixed a few random decoding bugs related to unaligned memory or buffers that were not initialized properly. (TheFluff)
- It is now possible to force FFMS2 to use a specific demuxer instead of letting it pick one automatically. (TheFluff)
- When converting YUV to RGB, FFMS2 will now try to actually use the correct color coefficients rather than assuming everything is bt470bg. (Plorkyeran)
- Moved support for container-level audio delay from the Avisynth plugin to the core and exposed it in the API (Plorkyeran)
- Audio decoding has been substantially reworked. Linearly decoding audio now almost always works correctly and seeking is now actually sample-accurate for many formats. (Plorkyeran)
- It is now possible to build 64bit versions of the plugin for use with Avisynth (and whatever else) from MSVC by means of black magic (this probably only works when the planets are aligned, also 64bit builds might require msvcr90.dll). (TheRyuu)
- The Avisynth plugin now supports UTF8 filenames; ffmsindex.exe also supports Unicode filenames. FFMS_USE_UTF8_PATHS is now a runtime option instead of a compile-time one. (TheFluff)
- The FFInfo() function (supplied by ffms2.avsi) will now round timestamps to nearest millisecond instead of truncating them. It's also been cleaned up in general and no longer relies on global variables. (Gavino)
- Containers opened with libavformat will now report a framerate based on the average frame duration instead of the duration of the first frame, just like Matroska files and files opened with Haali's splitter does. Should fix CFR framerates being reported incorrectly in dumb containers like FLV. (TheFluff)
- PC/TV luma range (16-235 versus 0-255) detection should now be a bit more reliable. (TheFluff)
- Fixed a crash when opening files with Unicode filename support enabled. (Plorkyeran)
- 2.14
- Reworked filename handling a bit. Index files should no longer get a garbled name when using the Avisynth plugin and an input filename in the local codepage (issue 9), and FFMS_USE_UTF8_PATHS does no longer require patching ffmpeg. (TheFluff, nielsm)
- Fixed a bunch of compiler warnings and added versioning for the shared library when building under Unix. (Kovensky)
- Fixed an invalid memory access bug that could cause random crashes or other errors when opening files. (TheFluff)
- The timebase for video tracks is now corrected if it's invalid. (kemuri_-9)
- Fixed a number of multithreaded decoding issues. (kemuri_-9)
- Use aligned memory for audio decoding buffers; fixes some crashes during audio decoding. (greg)
- Fixed a bug that caused ffmsindex -c to fail. (chdheu)
- Added support for MKV files using header stripping compression. (TheFluff)
- It is now possible to compile FFMS2 using a ffmpeg without libpostproc compiled in (this will obviously cause postprocessing-related functions to fail). Hence it is now possible to build a GPL-free FFMS2, since the rest of ffmpeg can be compiled as LGPL. (TheFluff)
- Audio streams that change channel layout, sample rate or bitdepth mid-stream will no longer cause crashes; an error will be raised during indexing instead. (TheFluff)
- Fix a potential crash when ffmpeg thought it couldn't decode a certain format, but was wrong. Fixes issues with some FLV's. (Plorkyeran)
- Fix heap corruption that could cause crashes and odd issues when opening H.264 in MPEG-TS with Haali's splitter. (Plorkyeran)
- Fix a memleak when decoding H.264 in MPEG-TS using Haali's splitter. (kemuri-_9)
- Updated FFmpeg to rev 25329.
- 2.13
- Fixed a bug where the Avisynth plugin would drop the last frame when converting to CFR (lanwcp)
- The Avisynth plugin will now attempt to detect and use NTSC fractional framerates for CFR files if applicable, instead of reporting something based on the average framerate (astrange, TheFluff)
- The errorhandling parameter to FFIndex() will now actually do what the documentation claims it does (TheFluff)
- Fixed a progress reporting crash when opening images (TheFluff)
- Replaced the CMake build system with an autotools one that hopefully works better (Kovensky)
- Fixed various compilation issues with MinGW (TheFluff)
- Fixed h264 in mkv which was remuxed from bd sources, there are no longer decoding artifacts after seeking
- Use pts instead of dts for seeking with lavf, fixes various timecode problems on mp4 files with certain obscure delay headers
- Now compresses the index files with zlib to save space
- Removed the boost dependency
- Fixed the framerate calculation for AVC video in the RFF modes
- Improved/fixed the NVOP detection in MPEG4 and how timestamps are calculated (lanwcp, Myrsloik)
- Fixed an issue where the first 15 audio frames would never be redecoded if needed again
- Fixed/added support for uncompressed video and audio formats in matroska, fixes Blank.Clip.720p.x264-darkhold.mkv (Emess)
- The indexer and test is now statically linked so no extra runtimes are needed
- FFmpeg is now compiled with runtime cpu detection, allows opterons and old cpus to work properly
- Updated FFmpeg to rev 21782
- 2.12
- Added support for (L)PCM in TS/PS
- Fixed some possible memory corruption on initialization in the indexers
- Improved the API slightly by making resolution and colorspace frame properties only like they actually are
- Fixed adjustdelay=-1 when no video track is present, previously it would crash
- Updated FFmpeg to rev 19824, FFmpeg-mt unchanged at 24/08/2009 - with faad2, opencore-amr nb/wb, and pthreads
- 2.11
- Now 100% less beta
- FFMSIndex can now write timecode files
- Optimized index reading and writing, file opening should be faster especially for big files
- Fixed a crash bug on zlib compressed streams in matroska
- Added an argument to FFAudioSource that makes it automatically adjust the delay relative to the first video track (default), the specified track (any track type possible) or relative to the zero timestamp, no adjustment is done for files with no video track in the default mode
- Now exports the colorimetry info in a format easily usable with ColorMatrix, see FFCOLOR_SPACE and FFCOLOR_RANGE in the manual, the reported information may be unreliable
- Added an FFImageSource() function to ffms2.avsi which invokes FFVideoSource with the optimal settings for use on images
- Now exports the actual frame presentation time in FFVFR_TIME, added the general information function FFInfo() and FFFormatTime() functions to ffms2.avsi in addition to fixing the missing backslash
- The seek/read method has been changed in the matroska video source to only need the information in the index and nothing more, this matches the audio source and should make seeking faster in some cases
- No longer drops the last audio frame
- It is now possible to force indexing of broken tracks when using FFIndex and from the API, this can in many cases help when the last frame of an avi file is corrupted which would otherwise prevent indexing of all working data
- Fixed a bug that would prevent the SWScale and FFPP filters from working because of randomly added flags
- Added support for RFF flags, the three possible modes should be equivalent to the ones found in DGDecode
- Added a workaround for mpeg4 files with NVOPs
- Fixed a bug where the first frame would be corrupted if the colorspace/dimensions were set for the output
- Now VC1 in TS decoding works in many cases
- Added the missing install target to CMake and changed the default output library name (Kovensky)
- Now reverts to using LAVF if Haali's splitter isn't installed (note that LAVF is VERY bad at seeking in these formats)
- Now requires the boost headers (but not libraries) to compile because boost::format is so convenient
- More API changes to return proper error codes and more source cleanups
- Updated FFmpeg to rev 19776, FFmpeg-mt to 24/08/2009 - with faad2, opencore-amr nb/wb, and w32threads (pthreads for FFmpeg-mt)
- 2.00 beta 10
- Possibly fixed h264 in transport stream decoding, now a suitable bitstream filter is added (could theoretically break other h264 in ts files so make sure to report if any such files stop working)
- Now returns the frame type as a character to make presentation easier and to remove the random numbers from the API
- Fixed the identification of certain codecs (like VC1) in some transport streams
- Fixed a bug introduced in SeekMode=1 by the changes in beta 6, prevents an access violation from happening in very rare conditions
- Some (but not all) stream properties are now retrieved from the container and passed to libavcodec, this makes a few more formats work like vc1 in mkv/ts
- It is now possible to specify the desired output colorspace and resolution in FFVideoSource, this is mostly useful for file where the resolution changes to avoid excessive up/downscaling
- Added support for files where the video frames have changing size and colorspace
- The library part can now be compiled to accept UTF8 encoded strings, this allows full unicode support on windows when FFmpeg is compiled with a small patch applied (TheFluff)
- Added proper detection of when the opened file and index is mismatched and throws an error when it happens instead of undefined behavior, should not add a noticable delay to file opening
- Added a proper cmake based build system and vs2008 project files to make developement and use easier (TheFluff, JEEB, Kovensky)
- Added API documentation by TheFluff and revised many argument descriptions to reflect how they currently work
- The output audio filename can now be specified in avisynth (was ignored previously) with variables such as track number and delay possible to use
- Indexing with Haali's splitters should now show progress in most cases
- Fixed a few more memory leaks in indexing
- Now checks for failed seeking when LAVF is used and retries with more aggressive seeking options before failing
- Updated FFmpeg to rev 19479 (now compiled with the opencore amr decoder)
- 2.00 beta 9
- Dumping audio now actually implies indexing too in FFIndex, previously nothing would be done if the index mask wasn't set as well
- FFAudioSource will now first load the index and returns the first indexed audio track with track=-1, if no audio tracks are indexed or the chosen track isn't indexed the equivalent of FFIndex(indexmask = -1, overwrite = cache) is executed first
- Codec lookup for non-lavf opened files now to a large part use the same lookup tables as lavf, this should improve the number of properly recognized codecs
- Now uses the average framerate for files opened with Haali's splitters, before it was always reported as 30 fps
- Implemented audio decoding using Haali's splitters, FFAudioSource now works on ts, ps and ogm
- Can now be compiled with ICL 10.1 (probably other versions too)
- How indexing works has been split internally so the track numbers and types are reported, this makes it possible to create an interactive GUI or ask which audio tracks are to be indexed
- Now has stricter index checking to detect when different FFmpeg versions were used to create an index of the same version
- Fixed memory leaks when audio sources were destroyed and when errors happened during indexing
- Fixed access violations occurring when a track of the wrong type was specified or didn't exist in FFVideoSource and FFAudioSource
- Fixed access violations occurring when unindexed or empty audio tracks in matroska/lavf read files were opened
- Less type conversion/signedness warnings
- When audio track dumping is performed a custom callback can now be supplied to name the tracks
- The audio track delay is now exposed in the API in the same way as video tracks
- A big type and argument name cleanup in the API, many things have been renamed to be clearer and ffms.h should be completely C friendly now
- Removed FFNoLog and replaced it with FFSetLogLevel and FFGetLogLevel, the default logging is now also set to quiet, the magical numbers to supply it can be found in avutil/log.h
- Updated FFmpeg to rev 18972 (now with faad2 again by popular demand, updated to GCC 4.4.0 for compiling all libraries)
- 2.00 beta 8
- Improved the audio decoding quality a lot by adding a simple cache, no more seeking is done when playing a file linearly and pops and other artifacts should be much more uncommon
- Fixed a bug that would most of the time drop frame 0 and sometimes frame 1
- Updated Haali's matroska parser code to the latest version
- Updated FFmpeg to rev 18774
- 2.00 beta 7
- Using ffms2 as a library no longer requires an installed pixfmt.h from libavutil, it is however still required to compile ffms2 and the avisynth plugin part
- Fix a crash bug at the end of files with b-frames in beta 6 caused by uninitialized null packets
- Includes TheFluff's wrapper function for 1.21 style syntax
- Added a simple regression test application to the source
- Removed a few pointless functions from the API
- Fixed the accessing of codecprivate data with Haali's splitters
- Timecode output should be fixed to include decimals AND not be in scientific format
- Fixed a memory leak when using Haali's splitters
- Updated FFmpeg to rev 18717
- 2.00 beta 6
- Haali's splitters have been improved for video and now have audio dumping during indexing implemented
- SeekMode=1 has improved logic which will make it go back and decode more frames if necessary to figure out where it is, in theory SeekMode=0 should now be mostly obsolete
- Haali's splitters are now used to open mpeg ps and ogm in addition to mpeg ts, only ogm is frame accurate at this time
- Negative timecodes and other bugs caused by an integer overflow fixed
- Updated FFmpeg to rev 18442 (once again compilation fixes for the changes)
- 2.00 beta 5
- FFMSIndex should now print the progress properly when another application reads its output
- Added missing variables and explanations to the manual
- Can now directly be compiled as a library for use in *nix
- Fixed the missing decimals in saved timecode files
- 2.00 beta 4
- Added the function FFNoLog which suppresses all messages from ffmpeg
- Experimental new TS parsing using Haali's splitter (with bugs)
- Everything is now compiled with VS2008 and GCC 4.3.2
- Updated FFmpeg to rev 16383 (no libfaad2 this time)
- 2.00 beta 3
- Compiled with libfaad2 again (has anyone seen a single aac file lavc can open right now?)
- More API changes (and even more are likely to come)
- Several access violations and memory leaks on opening and indexing files fixed
- Added a VFR to CFR mode
- Readded FFAudioSource support for other containers (glitches still present now and then but no separate raw cache is required and possibly less buggy)
- Renamed the dll to FFMS2.dll, FFMS2 is now the official short name of the project
- Updated FFmpeg to rev 15522
- 2.00 beta 2
- More API changes (and more are likely to come)

# FFmpegSource2 VapourSynth User Manual
Opens files using FFmpeg and (almost) nothing else.
May be frame accurate on good days.
The source is MIT licensed and can be obtained from https://github.com/FFMS/ffms2/.
The precompiled binary is GPL3 licensed.
If you are religious you may consider this the second coming.

## Limitations
- No audio support in VapourSynth
- Because of LAVF's demuxer, most raw streams (such as elementary h264 and other mpeg video streams) will fail to work properly.
- Interlaced H.264 mostly works these days, but seeking may occasionally result in corruption.
- Transport Streams will not decode reliably without seekmode -1.
- Open-GOP H.264 will sometimes produces corruption when seeking.
## Compatibility
- AVI, MKV, MP4, FLV: Frame accurate
- WMV: Frame accurate(?) but avformat seems to pick keyframes relatively far away
- OGM: Frame accurate(?)
- VOB, MPG: Seeking seems to be off by one or two frames now and then
- M2TS, TS: Seeking seems to be off a few frames here and there
- Image files: Most formats can be opened if seekmode=-1 is set, no animation support
## Indexing and You
Before FFMS2 can open a file, it must be indexed first so that keyframe/sample positions are known and seeking is easily accomplished.
This is done automatically when using `Source()`,
but if you want to you can invoke the indexing yourself by calling `Index()`, or by running `ffmsindex`.
By default the index is written to a file so it can be reused the next time you open the same file, but this behavior can be turned off if desired.
If you wonder why FFMS2 takes so long opening files, the indexing is the answer.
If you want a progress report on the indexing, you can use the supplied `ffmsindex` commandline program.
## Function reference
### Index
```
ffms2.Index(string source[, string cachefile = source + ".ffindex", int[] indextracks = [],
int errorhandling = 3, bint overwrite = False])
```
Indexes a number of tracks in a given source file and writes the index file to disk, where it can be picked up and used by `Source`.
Normally you do not need to call this function manually; it's invoked automatically if necessary by `Source`.
It does, however, give you more control over how indexing is done.
Note that this function returns an integer, not a clip (since it doesn't open video, nor audio).
The return value isn't particularly interesting, but for the record it's 0 if the index file already exists (and is valid) and overwrite was not enabled, 1 if the index file was created and no previous index existed, and 2 if the index file was created by overwriting an existing, valid index file.
#### Arguments
##### string source
The source file to index.
##### string cachefile = source + ".ffindex"
The filename of the index file (where the indexing data is saved).
Defaults to `sourcefilename.ffindex`.
##### int[] indextracks = []
An array containing a list of which audio tracks should be indexed (all video tracks are always indexed; you have no choice in the matter).
It's possible to use -1 to simply tell it to index all tracks.´without having to list them individually.
Note that FFMS2's idea about what track has what number may be completely different from what any other application might think.
##### int errorhandling = 3
Controls what happens if an audio decoding error is encountered during indexing.
Possible values are:
- **0**: Raise an error and abort indexing. No index file is written.
- **1**: Clear the affected track (effectively making it silent) and continue.
- **2**: Stop indexing the track but keep all the index entries so far, effectively ending the track where the error occured.
- **3**: Pretend it's raining and continue anyway. This is the default; if you encounter odd noises in the audio, try mode 0 instead and see if it's FFMS2's fault.
##### bint overwrite = False
If set to true, `FFIndex()` will reindex the source file and overwrite the index file even if the index file already exists and is valid.
Mostly useful for trackmask changes and testing.
### Source
```
ffms2.Source(string source[, int track = -1, bint cache = True,
string cachefile = source + ".ffindex", int fpsnum = -1, int fpsden = 1,
int threads = -1, string timecodes = "", int seekmode = 1,
int width = -1, int height = -1, string resizer = "BICUBIC",
int format, bint alpha = False])
```
Opens video. Will invoke indexing of all video tracks (but no audio tracks) if no valid index file is found.
#### Arguments
##### string source
The source file to open.
##### int track = -1
The video track number to open, as seen by the relevant demuxer.
Track numbers start from zero, and are guaranteed to be continous (i.e. there must be a track 1 if there is a track 0 and a track 2). -1 means open the first video track.
Note that FFMS2's idea about what track has what number may (or may not) be completely different from what some other application might think.
##### bint cache = True
If set to true (the default), `Source` will first check if the `cachefile` contains a valid index, and if it does, that index will be used.
If no index is found, all video tracks will be indexed, and the indexing data will be written to `cachefile` afterwards.
If set to false, `Source` will not look for an existing index file; instead all video tracks will be indexed when the script is opened, and the indexing data will be discarded after the script is closed; you will have to index again next time you open the script.
##### string cachefile = source + ".ffindex"
The filename of the index file (where the indexing data is saved).
Defaults to `sourcefilename.ffindex`.
Note that if you didn't change this parameter from its default value and `Source` encounters an index file that doesn't seem to match the file it's trying to open, it will automatically reindex and then overwrite the old index file.
On the other hand, if you *do* change it, `Source` will assume you have your reasons and throw an error instead if the index doesn't match the file.
##### int fpsnum = -1, int fpsden = 1
Controls the framerate of the output; used for VFR to CFR conversions.
If `fpsnum` is less than or equal to zero (the default), the output will contain the same frames that the input did, and the frame rate reported to VapourSynth will be set based on the input clip's average frame duration.
If `fpsnum` is greater than zero, `Source` will force a constant frame rate, expressed as a rational number where `fpsnum` is the numerator and `fpsden` is the denominator.
This may naturally cause `Source` to drop or duplicate frames to achieve the desired frame rate, and the output is not guaranteed to have the same number of frames that the input did.
##### int threads = -1
The number of decoding threads to request from libavcodec.
Setting it to less than or equal to zero means it defaults to the number of logical CPU's reported by the OS.
Note that this setting might be completely ignored by libavcodec under a number of conditions; most commonly because a lot of decoders actually do not support multithreading.
##### string timecodes = ""
Filename to write Matroska v2 timecodes for the opened video track to.
If the file exists, it will be truncated and overwritten.
Set to the empty string to disable timecodes writing (this is the default).
##### int seekmode = 1
Controls how seeking is done.
Mostly useful for getting uncooperative files to work.
Valid modes are:
- **-1**: Linear access without rewind; i.e. will throw an error if each successive requested frame number isn't bigger than the last one.
Only intended for opening images but might work on well with some obscure video format.
- **0**: Linear access (i.e. if you request frame `n` without having requested all frames from 0 to `n-1` in order first, all frames from 0 to `n` will have to be decoded before `n` can be delivered).
The definition of slow, but should make some formats "usable".
- **1**: Safe normal. Bases seeking decisions on the keyframe positions reported by libavformat.
- **2**: Unsafe normal. Same as mode 1, but no error will be thrown if the exact seek destination has to be guessed.
- **3**: Aggressive. Seeks in the forward direction even if no closer keyframe is known to exist. Only useful for testing and containers where libavformat doesn't report keyframes properly.
##### int width = -1, int height = -1
Sets the resolution of the output video, in pixels.
Setting either dimension to less than or equal to zero means the resolution of the first decoded video frame is used for that dimension.
These parameters are mostly useful because FFMS2 supports video streams that change resolution mid-stream which would otherwise have to be handled with a more complicated script.
##### string resizer = "BICUBIC"
The resizing algorithm to use if rescaling the image is necessary.
If the video uses subsampled chroma but your chosen output colorspace does not, the chosen resizer will be used to upscale the chroma planes, even if you did not request an image rescaling.
The available choices are `FAST_BILINEAR`, `BILINEAR`, `BICUBIC` (default), `X`, `POINT`, `AREA`, `BICUBLIN`, `GAUSS`, `SINC`, `LANCZOS` and `SPLINE`.
##### int format
Convert the output from whatever it was to the given format. If not specified the best matching output format is used.
##### bint alpha = False
Output the alpha channel as a second clip if it is present in the file. When set to True an array of two clips will be returned with alpha in the second one. If there is alpha information present.
#### Exported VapourSynth frame properties
There are several useful frame properties that are set. See the VapourSynth manual for a detailed explanation of them.
- _DurationNum
- _DurationDen
- _AbsoluteTime
- _SARNum
- _SARDen
- _Matrix
- _Primaries
- _Transfer
- _ChromaLocation
- _ColorRange
- _PictType
- _FieldBased
### SetLogLevel
```
ffms2.SetLogLevel(int Level = -8)
```
Sets the FFmpeg logging level, i.e. how much diagnostic spam it prints to STDERR.
Since many applications that open VapourSynth scripts do not provide a way to display things printed to STDERR, and since it's rather hard to make any sense of the printed messages unless you're quite familiar with FFmpeg internals, the usefulness of this function is rather limited for end users. It's mostly intended for debugging.
Defaults to quiet (no messages printed); a list of meaningful values can be found in `ffms.h`.
### GetLogLevel
```
ffms2.GetLogLevel()
```
Returns the current log level, as an integer.
### GetVersion
```
ffms2.GetVersion()
```
Returns the FFMS2 version, as a string.

GNU GENERAL PUBLIC LICENSE
Version 3, 29 June 2007
Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
Preamble
The GNU General Public License is a free, copyleft license for
software and other kinds of works.
The licenses for most software and other practical works are designed
to take away your freedom to share and change the works. By contrast,
the GNU General Public License is intended to guarantee your freedom to
share and change all versions of a program--to make sure it remains free
software for all its users. We, the Free Software Foundation, use the
GNU General Public License for most of our software; it applies also to
any other work released this way by its authors. You can apply it to
your programs, too.
When we speak of free software, we are referring to freedom, not
price. Our General Public Licenses are designed to make sure that you
have the freedom to distribute copies of free software (and charge for
them if you wish), that you receive source code or can get it if you
want it, that you can change the software or use pieces of it in new
free programs, and that you know you can do these things.
To protect your rights, we need to prevent others from denying you
these rights or asking you to surrender the rights. Therefore, you have
certain responsibilities if you distribute copies of the software, or if
you modify it: responsibilities to respect the freedom of others.
For example, if you distribute copies of such a program, whether
gratis or for a fee, you must pass on to the recipients the same
freedoms that you received. You must make sure that they, too, receive
or can get the source code. And you must show them these terms so they
know their rights.
Developers that use the GNU GPL protect your rights with two steps:
(1) assert copyright on the software, and (2) offer you this License
giving you legal permission to copy, distribute and/or modify it.
For the developers' and authors' protection, the GPL clearly explains
that there is no warranty for this free software. For both users' and
authors' sake, the GPL requires that modified versions be marked as
changed, so that their problems will not be attributed erroneously to
authors of previous versions.
Some devices are designed to deny users access to install or run
modified versions of the software inside them, although the manufacturer
can do so. This is fundamentally incompatible with the aim of
protecting users' freedom to change the software. The systematic
pattern of such abuse occurs in the area of products for individuals to
use, which is precisely where it is most unacceptable. Therefore, we
have designed this version of the GPL to prohibit the practice for those
products. If such problems arise substantially in other domains, we
stand ready to extend this provision to those domains in future versions
of the GPL, as needed to protect the freedom of users.
Finally, every program is threatened constantly by software patents.
States should not allow patents to restrict development and use of
software on general-purpose computers, but in those that do, we wish to
avoid the special danger that patents applied to a free program could
make it effectively proprietary. To prevent this, the GPL assures that
patents cannot be used to render the program non-free.
The precise terms and conditions for copying, distribution and
modification follow.
TERMS AND CONDITIONS
0. Definitions.
"This License" refers to version 3 of the GNU General Public License.
"Copyright" also means copyright-like laws that apply to other kinds of
works, such as semiconductor masks.
"The Program" refers to any copyrightable work licensed under this
License. Each licensee is addressed as "you". "Licensees" and
"recipients" may be individuals or organizations.
To "modify" a work means to copy from or adapt all or part of the work
in a fashion requiring copyright permission, other than the making of an
exact copy. The resulting work is called a "modified version" of the
earlier work or a work "based on" the earlier work.
A "covered work" means either the unmodified Program or a work based
on the Program.
To "propagate" a work means to do anything with it that, without
permission, would make you directly or secondarily liable for
infringement under applicable copyright law, except executing it on a
computer or modifying a private copy. Propagation includes copying,
distribution (with or without modification), making available to the
public, and in some countries other activities as well.
To "convey" a work means any kind of propagation that enables other
parties to make or receive copies. Mere interaction with a user through
a computer network, with no transfer of a copy, is not conveying.
An interactive user interface displays "Appropriate Legal Notices"
to the extent that it includes a convenient and prominently visible
feature that (1) displays an appropriate copyright notice, and (2)
tells the user that there is no warranty for the work (except to the
extent that warranties are provided), that licensees may convey the
work under this License, and how to view a copy of this License. If
the interface presents a list of user commands or options, such as a
menu, a prominent item in the list meets this criterion.
1. Source Code.
The "source code" for a work means the preferred form of the work
for making modifications to it. "Object code" means any non-source
form of a work.
A "Standard Interface" means an interface that either is an official
standard defined by a recognized standards body, or, in the case of
interfaces specified for a particular programming language, one that
is widely used among developers working in that language.
The "System Libraries" of an executable work include anything, other
than the work as a whole, that (a) is included in the normal form of
packaging a Major Component, but which is not part of that Major
Component, and (b) serves only to enable use of the work with that
Major Component, or to implement a Standard Interface for which an
implementation is available to the public in source code form. A
"Major Component", in this context, means a major essential component
(kernel, window system, and so on) of the specific operating system
(if any) on which the executable work runs, or a compiler used to
produce the work, or an object code interpreter used to run it.
The "Corresponding Source" for a work in object code form means all
the source code needed to generate, install, and (for an executable
work) run the object code and to modify the work, including scripts to
control those activities. However, it does not include the work's
System Libraries, or general-purpose tools or generally available free
programs which are used unmodified in performing those activities but
which are not part of the work. For example, Corresponding Source
includes interface definition files associated with source files for
the work, and the source code for shared libraries and dynamically
linked subprograms that the work is specifically designed to require,
such as by intimate data communication or control flow between those
subprograms and other parts of the work.
The Corresponding Source need not include anything that users
can regenerate automatically from other parts of the Corresponding
Source.
The Corresponding Source for a work in source code form is that
same work.
2. Basic Permissions.
All rights granted under this License are granted for the term of
copyright on the Program, and are irrevocable provided the stated
conditions are met. This License explicitly affirms your unlimited
permission to run the unmodified Program. The output from running a
covered work is covered by this License only if the output, given its
content, constitutes a covered work. This License acknowledges your
rights of fair use or other equivalent, as provided by copyright law.
You may make, run and propagate covered works that you do not
convey, without conditions so long as your license otherwise remains
in force. You may convey covered works to others for the sole purpose
of having them make modifications exclusively for you, or provide you
with facilities for running those works, provided that you comply with
the terms of this License in conveying all material for which you do
not control copyright. Those thus making or running the covered works
for you must do so exclusively on your behalf, under your direction
and control, on terms that prohibit them from making any copies of
your copyrighted material outside their relationship with you.
Conveying under any other circumstances is permitted solely under
the conditions stated below. Sublicensing is not allowed; section 10
makes it unnecessary.
3. Protecting Users' Legal Rights From Anti-Circumvention Law.
No covered work shall be deemed part of an effective technological
measure under any applicable law fulfilling obligations under article
11 of the WIPO copyright treaty adopted on 20 December 1996, or
similar laws prohibiting or restricting circumvention of such
measures.
When you convey a covered work, you waive any legal power to forbid
circumvention of technological measures to the extent such circumvention
is effected by exercising rights under this License with respect to
the covered work, and you disclaim any intention to limit operation or
modification of the work as a means of enforcing, against the work's
users, your or third parties' legal rights to forbid circumvention of
technological measures.
4. Conveying Verbatim Copies.
You may convey verbatim copies of the Program's source code as you
receive it, in any medium, provided that you conspicuously and
appropriately publish on each copy an appropriate copyright notice;
keep intact all notices stating that this License and any
non-permissive terms added in accord with section 7 apply to the code;
keep intact all notices of the absence of any warranty; and give all
recipients a copy of this License along with the Program.
You may charge any price or no price for each copy that you convey,
and you may offer support or warranty protection for a fee.
5. Conveying Modified Source Versions.
You may convey a work based on the Program, or the modifications to
produce it from the Program, in the form of source code under the
terms of section 4, provided that you also meet all of these conditions:
a) The work must carry prominent notices stating that you modified
it, and giving a relevant date.
b) The work must carry prominent notices stating that it is
released under this License and any conditions added under section
7. This requirement modifies the requirement in section 4 to
"keep intact all notices".
c) You must license the entire work, as a whole, under this
License to anyone who comes into possession of a copy. This
License will therefore apply, along with any applicable section 7
additional terms, to the whole of the work, and all its parts,
regardless of how they are packaged. This License gives no
permission to license the work in any other way, but it does not
invalidate such permission if you have separately received it.
d) If the work has interactive user interfaces, each must display
Appropriate Legal Notices; however, if the Program has interactive
interfaces that do not display Appropriate Legal Notices, your
work need not make them do so.
A compilation of a covered work with other separate and independent
works, which are not by their nature extensions of the covered work,
and which are not combined with it such as to form a larger program,
in or on a volume of a storage or distribution medium, is called an
"aggregate" if the compilation and its resulting copyright are not
used to limit the access or legal rights of the compilation's users
beyond what the individual works permit. Inclusion of a covered work
in an aggregate does not cause this License to apply to the other
parts of the aggregate.
6. Conveying Non-Source Forms.
You may convey a covered work in object code form under the terms
of sections 4 and 5, provided that you also convey the
machine-readable Corresponding Source under the terms of this License,
in one of these ways:
a) Convey the object code in, or embodied in, a physical product
(including a physical distribution medium), accompanied by the
Corresponding Source fixed on a durable physical medium
customarily used for software interchange.
b) Convey the object code in, or embodied in, a physical product
(including a physical distribution medium), accompanied by a
written offer, valid for at least three years and valid for as
long as you offer spare parts or customer support for that product
model, to give anyone who possesses the object code either (1) a
copy of the Corresponding Source for all the software in the
product that is covered by this License, on a durable physical
medium customarily used for software interchange, for a price no
more than your reasonable cost of physically performing this
conveying of source, or (2) access to copy the
Corresponding Source from a network server at no charge.
c) Convey individual copies of the object code with a copy of the
written offer to provide the Corresponding Source. This
alternative is allowed only occasionally and noncommercially, and
only if you received the object code with such an offer, in accord
with subsection 6b.
d) Convey the object code by offering access from a designated
place (gratis or for a charge), and offer equivalent access to the
Corresponding Source in the same way through the same place at no
further charge. You need not require recipients to copy the
Corresponding Source along with the object code. If the place to
copy the object code is a network server, the Corresponding Source
may be on a different server (operated by you or a third party)
that supports equivalent copying facilities, provided you maintain
clear directions next to the object code saying where to find the
Corresponding Source. Regardless of what server hosts the
Corresponding Source, you remain obligated to ensure that it is
available for as long as needed to satisfy these requirements.
e) Convey the object code using peer-to-peer transmission, provided
you inform other peers where the object code and Corresponding
Source of the work are being offered to the general public at no
charge under subsection 6d.
A separable portion of the object code, whose source code is excluded
from the Corresponding Source as a System Library, need not be
included in conveying the object code work.
A "User Product" is either (1) a "consumer product", which means any
tangible personal property which is normally used for personal, family,
or household purposes, or (2) anything designed or sold for incorporation
into a dwelling. In determining whether a product is a consumer product,
doubtful cases shall be resolved in favor of coverage. For a particular
product received by a particular user, "normally used" refers to a
typical or common use of that class of product, regardless of the status
of the particular user or of the way in which the particular user
actually uses, or expects or is expected to use, the product. A product
is a consumer product regardless of whether the product has substantial
commercial, industrial or non-consumer uses, unless such uses represent
the only significant mode of use of the product.
"Installation Information" for a User Product means any methods,
procedures, authorization keys, or other information required to install
and execute modified versions of a covered work in that User Product from
a modified version of its Corresponding Source. The information must
suffice to ensure that the continued functioning of the modified object
code is in no case prevented or interfered with solely because
modification has been made.
If you convey an object code work under this section in, or with, or
specifically for use in, a User Product, and the conveying occurs as
part of a transaction in which the right of possession and use of the
User Product is transferred to the recipient in perpetuity or for a
fixed term (regardless of how the transaction is characterized), the
Corresponding Source conveyed under this section must be accompanied
by the Installation Information. But this requirement does not apply
if neither you nor any third party retains the ability to install
modified object code on the User Product (for example, the work has
been installed in ROM).
The requirement to provide Installation Information does not include a
requirement to continue to provide support service, warranty, or updates
for a work that has been modified or installed by the recipient, or for
the User Product in which it has been modified or installed. Access to a
network may be denied when the modification itself materially and
adversely affects the operation of the network or violates the rules and
protocols for communication across the network.
Corresponding Source conveyed, and Installation Information provided,
in accord with this section must be in a format that is publicly
documented (and with an implementation available to the public in
source code form), and must require no special password or key for
unpacking, reading or copying.
7. Additional Terms.
"Additional permissions" are terms that supplement the terms of this
License by making exceptions from one or more of its conditions.
Additional permissions that are applicable to the entire Program shall
be treated as though they were included in this License, to the extent
that they are valid under applicable law. If additional permissions
apply only to part of the Program, that part may be used separately
under those permissions, but the entire Program remains governed by
this License without regard to the additional permissions.
When you convey a copy of a covered work, you may at your option
remove any additional permissions from that copy, or from any part of
it. (Additional permissions may be written to require their own
removal in certain cases when you modify the work.) You may place
additional permissions on material, added by you to a covered work,
for which you have or can give appropriate copyright permission.
Notwithstanding any other provision of this License, for material you
add to a covered work, you may (if authorized by the copyright holders of
that material) supplement the terms of this License with terms:
a) Disclaiming warranty or limiting liability differently from the
terms of sections 15 and 16 of this License; or
b) Requiring preservation of specified reasonable legal notices or
author attributions in that material or in the Appropriate Legal
Notices displayed by works containing it; or
c) Prohibiting misrepresentation of the origin of that material, or
requiring that modified versions of such material be marked in
reasonable ways as different from the original version; or
d) Limiting the use for publicity purposes of names of licensors or
authors of the material; or
e) Declining to grant rights under trademark law for use of some
trade names, trademarks, or service marks; or
f) Requiring indemnification of licensors and authors of that
material by anyone who conveys the material (or modified versions of
it) with contractual assumptions of liability to the recipient, for
any liability that these contractual assumptions directly impose on
those licensors and authors.
All other non-permissive additional terms are considered "further
restrictions" within the meaning of section 10. If the Program as you
received it, or any part of it, contains a notice stating that it is
governed by this License along with a term that is a further
restriction, you may remove that term. If a license document contains
a further restriction but permits relicensing or conveying under this
License, you may add to a covered work material governed by the terms
of that license document, provided that the further restriction does
not survive such relicensing or conveying.
If you add terms to a covered work in accord with this section, you
must place, in the relevant source files, a statement of the
additional terms that apply to those files, or a notice indicating
where to find the applicable terms.
Additional terms, permissive or non-permissive, may be stated in the
form of a separately written license, or stated as exceptions;
the above requirements apply either way.
8. Termination.
You may not propagate or modify a covered work except as expressly
provided under this License. Any attempt otherwise to propagate or
modify it is void, and will automatically terminate your rights under
this License (including any patent licenses granted under the third
paragraph of section 11).
However, if you cease all violation of this License, then your
license from a particular copyright holder is reinstated (a)
provisionally, unless and until the copyright holder explicitly and
finally terminates your license, and (b) permanently, if the copyright
holder fails to notify you of the violation by some reasonable means
prior to 60 days after the cessation.
Moreover, your license from a particular copyright holder is
reinstated permanently if the copyright holder notifies you of the
violation by some reasonable means, this is the first time you have
received notice of violation of this License (for any work) from that
copyright holder, and you cure the violation prior to 30 days after
your receipt of the notice.
Termination of your rights under this section does not terminate the
licenses of parties who have received copies or rights from you under
this License. If your rights have been terminated and not permanently
reinstated, you do not qualify to receive new licenses for the same
material under section 10.
9. Acceptance Not Required for Having Copies.
You are not required to accept this License in order to receive or
run a copy of the Program. Ancillary propagation of a covered work
occurring solely as a consequence of using peer-to-peer transmission
to receive a copy likewise does not require acceptance. However,
nothing other than this License grants you permission to propagate or
modify any covered work. These actions infringe copyright if you do
not accept this License. Therefore, by modifying or propagating a
covered work, you indicate your acceptance of this License to do so.
10. Automatic Licensing of Downstream Recipients.
Each time you convey a covered work, the recipient automatically
receives a license from the original licensors, to run, modify and
propagate that work, subject to this License. You are not responsible
for enforcing compliance by third parties with this License.
An "entity transaction" is a transaction transferring control of an
organization, or substantially all assets of one, or subdividing an
organization, or merging organizations. If propagation of a covered
work results from an entity transaction, each party to that
transaction who receives a copy of the work also receives whatever
licenses to the work the party's predecessor in interest had or could
give under the previous paragraph, plus a right to possession of the
Corresponding Source of the work from the predecessor in interest, if
the predecessor has it or can get it with reasonable efforts.
You may not impose any further restrictions on the exercise of the
rights granted or affirmed under this License. For example, you may
not impose a license fee, royalty, or other charge for exercise of
rights granted under this License, and you may not initiate litigation
(including a cross-claim or counterclaim in a lawsuit) alleging that
any patent claim is infringed by making, using, selling, offering for
sale, or importing the Program or any portion of it.
11. Patents.
A "contributor" is a copyright holder who authorizes use under this
License of the Program or a work on which the Program is based. The
work thus licensed is called the contributor's "contributor version".
A contributor's "essential patent claims" are all patent claims
owned or controlled by the contributor, whether already acquired or
hereafter acquired, that would be infringed by some manner, permitted
by this License, of making, using, or selling its contributor version,
but do not include claims that would be infringed only as a
consequence of further modification of the contributor version. For
purposes of this definition, "control" includes the right to grant
patent sublicenses in a manner consistent with the requirements of
this License.
Each contributor grants you a non-exclusive, worldwide, royalty-free
patent license under the contributor's essential patent claims, to
make, use, sell, offer for sale, import and otherwise run, modify and
propagate the contents of its contributor version.
In the following three paragraphs, a "patent license" is any express
agreement or commitment, however denominated, not to enforce a patent
(such as an express permission to practice a patent or covenant not to
sue for patent infringement). To "grant" such a patent license to a
party means to make such an agreement or commitment not to enforce a
patent against the party.
If you convey a covered work, knowingly relying on a patent license,
and the Corresponding Source of the work is not available for anyone
to copy, free of charge and under the terms of this License, through a
publicly available network server or other readily accessible means,
then you must either (1) cause the Corresponding Source to be so
available, or (2) arrange to deprive yourself of the benefit of the
patent license for this particular work, or (3) arrange, in a manner
consistent with the requirements of this License, to extend the patent
license to downstream recipients. "Knowingly relying" means you have
actual knowledge that, but for the patent license, your conveying the
covered work in a country, or your recipient's use of the covered work
in a country, would infringe one or more identifiable patents in that
country that you have reason to believe are valid.
If, pursuant to or in connection with a single transaction or
arrangement, you convey, or propagate by procuring conveyance of, a
covered work, and grant a patent license to some of the parties
receiving the covered work authorizing them to use, propagate, modify
or convey a specific copy of the covered work, then the patent license
you grant is automatically extended to all recipients of the covered
work and works based on it.
A patent license is "discriminatory" if it does not include within
the scope of its coverage, prohibits the exercise of, or is
conditioned on the non-exercise of one or more of the rights that are
specifically granted under this License. You may not convey a covered
work if you are a party to an arrangement with a third party that is
in the business of distributing software, under which you make payment
to the third party based on the extent of your activity of conveying
the work, and under which the third party grants, to any of the
parties who would receive the covered work from you, a discriminatory
patent license (a) in connection with copies of the covered work
conveyed by you (or copies made from those copies), or (b) primarily
for and in connection with specific products or compilations that
contain the covered work, unless you entered into that arrangement,
or that patent license was granted, prior to 28 March 2007.
Nothing in this License shall be construed as excluding or limiting
any implied license or other defenses to infringement that may
otherwise be available to you under applicable patent law.
12. No Surrender of Others' Freedom.
If conditions are imposed on you (whether by court order, agreement or
otherwise) that contradict the conditions of this License, they do not
excuse you from the conditions of this License. If you cannot convey a
covered work so as to satisfy simultaneously your obligations under this
License and any other pertinent obligations, then as a consequence you may
not convey it at all. For example, if you agree to terms that obligate you
to collect a royalty for further conveying from those to whom you convey
the Program, the only way you could satisfy both those terms and this
License would be to refrain entirely from conveying the Program.
13. Use with the GNU Affero General Public License.
Notwithstanding any other provision of this License, you have
permission to link or combine any covered work with a work licensed
under version 3 of the GNU Affero General Public License into a single
combined work, and to convey the resulting work. The terms of this
License will continue to apply to the part which is the covered work,
but the special requirements of the GNU Affero General Public License,
section 13, concerning interaction through a network will apply to the
combination as such.
14. Revised Versions of this License.
The Free Software Foundation may publish revised and/or new versions of
the GNU General Public License from time to time. Such new versions will
be similar in spirit to the present version, but may differ in detail to
address new problems or concerns.
Each version is given a distinguishing version number. If the
Program specifies that a certain numbered version of the GNU General
Public License "or any later version" applies to it, you have the
option of following the terms and conditions either of that numbered
version or of any later version published by the Free Software
Foundation. If the Program does not specify a version number of the
GNU General Public License, you may choose any version ever published
by the Free Software Foundation.
If the Program specifies that a proxy can decide which future
versions of the GNU General Public License can be used, that proxy's
public statement of acceptance of a version permanently authorizes you
to choose that version for the Program.
Later license versions may give you additional or different
permissions. However, no additional obligations are imposed on any
author or copyright holder as a result of your choosing to follow a
later version.
15. Disclaimer of Warranty.
THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
16. Limitation of Liability.
IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
SUCH DAMAGES.
17. Interpretation of Sections 15 and 16.
If the disclaimer of warranty and limitation of liability provided
above cannot be given local legal effect according to their terms,
reviewing courts shall apply local law that most closely approximates
an absolute waiver of all civil liability in connection with the
Program, unless a warranty or assumption of liability accompanies a
copy of the Program in return for a fee.
END OF TERMS AND CONDITIONS
How to Apply These Terms to Your New Programs
If you develop a new program, and you want it to be of the greatest
possible use to the public, the best way to achieve this is to make it
free software which everyone can redistribute and change under these terms.
To do so, attach the following notices to the program. It is safest
to attach them to the start of each source file to most effectively
state the exclusion of warranty; and each file should have at least
the "copyright" line and a pointer to where the full notice is found.
<one line to give the program's name and a brief idea of what it does.>
Copyright (C) <year> <name of author>
This program is free software: you can redistribute it and/or modify
it under the terms of the GNU General Public License as published by
the Free Software Foundation, either version 3 of the License, or
(at your option) any later version.
This program is distributed in the hope that it will be useful,
but WITHOUT ANY WARRANTY; without even the implied warranty of
MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
GNU General Public License for more details.
You should have received a copy of the GNU General Public License
along with this program. If not, see <http://www.gnu.org/licenses/>.
Also add information on how to contact you by electronic and paper mail.
If the program does terminal interaction, make it output a short
notice like this when it starts in an interactive mode:
<program> Copyright (C) <year> <name of author>
This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
This is free software, and you are welcome to redistribute it
under certain conditions; type `show c' for details.
The hypothetical commands `show w' and `show c' should show the appropriate
parts of the General Public License. Of course, your program's commands
might be different; for a GUI interface, you would use an "about box".
You should also get your employer (if you work as a programmer) or school,
if any, to sign a "copyright disclaimer" for the program, if necessary.
For more information on this, and how to apply and follow the GNU GPL, see
<http://www.gnu.org/licenses/>.
The GNU General Public License does not permit incorporating your program
into proprietary programs. If your program is a subroutine library, you
may consider it more useful to permit linking proprietary applications with
the library. If this is what you want to do, use the GNU Lesser General
Public License instead of this License. But first, please read
<http://www.gnu.org/philosophy/why-not-lgpl.html>.

# serial 5 lt~obsolete.m4
# These exist entirely to fool aclocal when bootstrapping libtool.
#
# In the past libtool.m4 has provided macros via AC_DEFUN (or AU_DEFUN),
# which have later been changed to m4_define as they aren't part of the
# exported API, or moved to Autoconf or Automake where they belong.
#
# The trouble is, aclocal is a bit thick. It'll see the old AC_DEFUN
# in /usr/share/aclocal/libtool.m4 and remember it, then when it sees us
# using a macro with the same name in our local m4/libtool.m4 it'll
# pull the old libtool.m4 in (it doesn't see our shiny new m4_define
# and doesn't know about Autoconf macros at all.)
#
# So we provide this file, which has a silly filename so it's always
# included after everything else. This provides aclocal with the
# AC_DEFUNs it wants, but when m4 processes it, it doesn't do anything
# because those macros already exist, or will be overwritten later.
# We use AC_DEFUN over AU_DEFUN for compatibility with aclocal-1.6.
#
# Anytime we withdraw an AC_DEFUN or AU_DEFUN, remember to add it here.
# Yes, that means every name once taken will need to remain here until
# we give up compatibility with versions before 1.7, at which point
# we need to keep only those names which we still refer to.
# This is to help aclocal find these macros, as it can't see m4_define.
