Dear All, I have some question about ffmpeg. In my code, I do not use encode and decode function. My data source has been encoded by hardware. 1. If I use ffmpeg to output mp4 file. Audio is AAC, 8000Hz, 1 channel, 16kbps. -> Do I need to insert extradata{0x15, 0x88} for AAC ?
2. If I use ffmpeg to output mp4 file. Video is H264, the h264 frame have nal header(SPS+PPS). -> Do I need to remove the nal header and insert 4 bytes(frame length description) before h264 frame ? -> Do I need to insert extradata{avcc} for H264 ? Anyone has ideal !!! Please help me, thanks a lot. -- View this message in context: http://libav-users.943685.n4.nabble.com/H264-AAC-output-mp4-file-tp3826859p3826859.html Sent from the libav-users mailing list archive at Nabble.com. _______________________________________________ Libav-user mailing list Libav-user@ffmpeg.org http://ffmpeg.org/mailman/listinfo/libav-user
