I've been trying to debug why the audio wasn't working...and wrote a simple demuxer only for the audio with a lot of info messages. The output on a sample file is as follows: FFplay version UNKNOWN, Copyright (c) 2003-2008 Fabrice Bellard, et al. configuration: libavutil version: 49.6.0 libavcodec version: 51.52.0 libavformat version: 52.11.0 libavdevice version: 52.0.0 built on Mar 25 2008 11:24:56, gcc: 4.1.3 20070929 (prerelease) (Ubuntu 4.1.2-16ubuntu2)

Surprisingly, the audio and video offsets displayed seem to be unusual according to the specs in the wiki. The audio offsets and the video offsets seem to be opposite to what is mentioned in the wiki. Can anyone please confirm if the specs in the wiki are 100% right? ----------------- Sisir Koppaka _______________________________________________ FFmpeg-soc mailing list [email protected] https://lists.mplayerhq.hu/mailman/listinfo/ffmpeg-soc
