|
* Mpp rate control principle
|
|
*
|
|
* 1. Rate control information is composed by these parts:
|
|
* a. configuration from mpp user.
|
|
* b. frame level target bitrate calculated by different RC model.
|
|
* c. block level hardware related configuration to hardware.
|
|
* d. statistic information from hardware after one frame is encoded.
|
|
*
|
|
* 2. All the above informatioin is storaged and managed by RcDataCtx in mpp
|
|
* framework. All these information is shared in encoder and hal module.
|
|
*
|
|
* 3. User (no matter developer or end user) defined rate control should based
|
|
* on these Rate control information and implement its own rate control
|
|
* strategy module by providing their own RcImplApi.
