What about a hardware accelerated decoding API/framework? Is there a 
proper framework for this at all? I see the broadcom module is still in 
staging and may never come out of it, but how are other video decoding 
engines handled that don't have cameras or displays.

Reason for asking is that we from linux-sunxi have made some positive 
progress in Reverse engineering the video decoder blob of the Allwinner 
A10 and this knowledge will need a kernel side driver in some framework. 
I looked at the exynos video decoders and googling for linux-media 
hardware accelerated decoding doesn't yield much either.

Anyway, just a thought; if you think it's the wrong place for it to be 
discussed, that's ok :)
