Yes, this exif flash tag is made of flags. Not sure how to represent those in
gstreamer tags. With my initial proposal we would only be able to set the first
bit (flash fired/flash not fired) which is probably the most important bit
there.

Any ideas on how to represent this? Using multiple different tags? Or a
"flash-type" string tag?
