  • Status changed from New to Rejected

No error here. First try updating FFmpeg to the latest version, then report the problem to the FFmpeg project if the problem persists.

This systematically happens with .mp4 videos files downloaded from YouTube and treated with MP4Box to extract the audio to a .m4a file. Would it be possible to ignore this error silently? Other players such as VLC do not indicate any problem. (Using Arch Linux, all packages current.)

This bug was already closed since it was not reproducible. If you have a test case for which Audacious reports and error and command-line ffmpeg does not, then please open a new report. If ffmpeg reports an error, then you can try reporting a bug to ffmpeg, but it is likely you have a corrupt file.
