If gstreamer will support exif, will it support only video and sound
files?
Do you plan to support all EXIF tags?
Or it make more sense to use some independent library?

Current gstreamer can't extract metadata on any files produced by
digital cameras, exaftool can. It handle even ogg, mov, avi, many image
formats ...
But it can't handle mkv files.
What longterm solution is better for example for tracker, to add mkv to
exiftool or to add exif to gstreamer?
