I am trying convert from FLV to MP4.
The convertion process returns no error, but the
resulted file has corrupted audio. Sounds like and a/v
sync issue.
Converting to mp3 or even wav results in no such

The command line: ffmpeg -i eric.flv -ab 128k eric.mp4

I uploaded also the FLV file that generates these

Thank you.
