#13: demuxing ogg track produces invalid ogg on 3rd pass ------------------------+--------------------- Reporter: gervin23 | Owner: michael Type: defect | Status: new Priority: important | Component: FFmpeg Version: 0.6 | Keywords: Blocked By: | Blocking: Reproduced: 0 | Analyzed: 0 ------------------------+--------------------- Each iteration of a demux on an ogg file will shave time and if done recursively will produce corrupted file on 3rd pass. Note, this doesn't happen with mp4 and I haven't tested other formats. For example, given a freshly produced and valid ogg from sox, a.ogg: '''ogginfo a.ogg''' Total data length: 63786 bytes Playback length: 0m:05.326s Average bitrate: 95.809353 kb/s '''ffmpeg -i a.ogg
