Attached patch should be a good starting point to list the conversion
tags from ffmpeg (and document its use in the manuals). It doesn't
list tags that are used for example in nut, which gets them using
av_metadata_get(). Maybe there could be a way for all tags to be
listed in AVOutputFormat.

Anyways, I don't plan on following up on this patch, it was just a
moment of boredom, feel free to pick it up if it's useful =). And
expect more replies from the metadata maintainers...
