 video stream before covnerting in ffmpeg 1.0 ?
 It may be sufficient if you can post a command line that works fine with
 an older version of ffmpeg but fails (or produces unexpected output) with
 current ffmpeg.

 So far, you have posted a command line - "ffmpeg -i
 diatonis_trajectories_08_the-secret-universe_4424_6-chan.flac' - that
 shows no cover art for ffmpeg 0.8, but shows cover art for ffmpeg 1.0.
 Assuming that there is cover art stored in your input file, I don't think
 this is sufficient explanation for a bug in ffmpeg 1.0, or don't you
 agree? (One could even argue that your command line implicates that there
 is a bug in ffmpeg 0.8 and that the fix should be backported, but patches
 that do not fix a regression and do not fix a security issue are normally
 not backported.)
