* Configure of encoder is separated into four parts.
|
|
*
|
|
* 1. Rate control parameter
|
|
* This is quality and bitrate request from user.
|
|
* For controller only
|
|
*
|
|
* 2. Data source MppFrame parameter
|
|
* This is data source buffer information.
|
|
* For both controller and hal
|
|
*
|
|
* 3. Video codec infomation
|
|
* This is user custormized stream information.
|
|
* For hal only
|
|
*
|
|
* 4. Extra parameter
|
|
* including:
|
|
* PreP : encoder Preprocess configuration
|
|
* ROI : Region Of Interest
|
|
* OSD : On Screen Display
|
|
* MD : Motion Detection
|
|
* extra : SEI for h.264 / Exif for mjpeg
|
|
* For hal only
