FFmpeg: what does av_parser_parse2 do?

QUESTION

FFmpeg: what does av_parser_parse2 do?

Asked 2018-Jun-28 at 16:15

When sending h264 data for frame decoding, it seems like a common method is to first call av_parser_parse2 from the libav library on the raw data.

I looked for documentation but I couldn't find anything other than some example codes. Does it group up packets of data so that the resulting data starts out with NAL headers so it can be perceived a frame?

The following is a link to a sample code that uses av_parser_parse2:

https://github.com/DJI-Mobile-SDK-Tutorials/Android-VideoStreamDecodingSample/blob/master/android-videostreamdecodingsample/jni/dji_video_jni.c

I would appreciate if anyone could explain those library details to me or link me resources for better understanding.

Thank you.

DJI's video transmission does not guarantee the data in each packet belongs to a single video frame. Mostly a packet contains only part of the data needed for a single frame. It also does not guarantee that a packet contains data from one frame and not two consecutive frames. Android's MediaCodec need to be queued with buffers, each holding the full data for a single frame. This is where av_parser_parse2() comes in. It gathers packets until it can find enough data for a full frame. This frame is then sent to MediaCodec for decoding.
