 Summary of the bug:
 While parsing audio files, FFprobe doesn't detect cover art in vorbis
 metadata the same way as for id3 or ape metadata:
 - id3/ape shows cover art as a 2nd video stream
 - vorbis comments shows cover art as a "METADATA_BLOCK_PICTURE"
 It would be good that cover art for vorbis comments also get processed as
 in id3/ape tags.

 Tested with those files:

 http://towerofbabel.free.fr/test/music.opus
 http://towerofbabel.free.fr/test/music.mp3
