Comment (by mkver):
FFmpeg (the project) aspires to be a generic tool and therefore normalizes
certain common tag names like "comment". For VorbisComment metadata, the
tag that gets mapped to comment in DESCRIPTION (this is defined in
ff_vorbiscomment_metadata_conv in libavformat/vorbiscomment.c). Therefore
the muxer converts a comment tag to DESCRIPTION and the demuxer converts a
DESCRIPTION to a comment. ffprobe uses said demuxer, so it reports
comment. So I fail to see the bug here. After all, your -metadata
'comment=this is a comment' has been preserved.
