Public bug reported:

  1) This video plays fine and audio sounds normal using ffplay.
  2) Video works fine, but audio is staticy in melt.
  3) Here are the details from ffmpeg about my video:

Input #0, mpeg, from 'M2U00302.MPG':
  Duration: 00:00:03.97, start: 0.221544, bitrate: 9110 kb/s
    Stream #0.0[0x1e0]: Video: mpeg2video, yuv420p, 720x480 [PAR 32:27 DAR 16:9], 9100 kb/s, 29.97 fps, 29.97 tbr, 90k tbn, 59.94 tbc
    Stream #0.1[0x80]: Audio: ac3, 48000 Hz, stereo, s16, 256 kb/s

  4) Yes, I have attached a small video which exhibits static in the
audio when playing with melt.


I have tested the same video on a second computer, which does not exhibit the same audio problem. I'm hoping it's just a case of a missing or incorrect version of some package. If it comes down to trying to convert the file to a different format using ffmpeg, what is the ideal format to convert it to with minimal (if any) loss of quality?

The following applies to both computers unless otherwise specified:
1) Ubuntu 10.10 x64
2) PPA
3) OpenShot 1.2.2
