(Can't seem to edit my earlier comment, so I'll continue here)
It seems like there's something strange going on with this GL extension.
Someone on the Kodi forum looked into this for me and found out that the
problem was that it's only partially supported. I'm not sure how this can or
should be fixed. 

If this is a hardware limitation, perhaps there should be some way to find out
if at least the one-way part of the extension is supported (from userspace). 

If it's only partially implemented in the radeon driver, perhaps this needs to
be completed. Or maybe the part that's implemented is good enough to enable the
extension, I don't know. 

But it seemed like it was worth mentioning to the appropriate people. There is
also mention of a 200ms (or 175ms to be exact) delay/latency for the video
processing (which means the video is lagging 200ms behind the audio) in the
Kodi thread. It's possible that it is not related to this, but I wanted to
mention it anyway (in case it is related).
