ffmpeg: how to save h264 raw data as mp4 file

Question

I encode h264 data by libavcodec. ex.

while (1) {
  ...
  avcodec_encode_video(pEnc->pCtx, OutBuf, ENC_OUTSIZE, pEnc->pYUVFrame);
  ...
}

If I directly save OutBuf data as a .264 file, it can`t be play by player. Now I want to save OutBuf

as a mp4 file. Anyone know how to do this by ffmpeg lib? thanks.

Answer 1

You use avformat_write_header, av_interleaved_write_frame, avformat_write_trailer and friends.

Their usage is shown in the muxing example of FFmpeg.
