Thanks for this very useful link!

I'll definitely have to study this uncommon vulkan dirac implementation and learn from it.

Its an example on how to accelerate via compute shaders. What he did was he simply introduced vc2_vulkan as a hwaccel. It makes sense, even for partially accelerated codecs, since the hwaccel infrastructure handles everything for you, **including a fallback for CPU decoding**, and users automatically get accelerated support.

Interesting! -- I wouldn't have expected this behavior...

I still have to look at more closely at this topic, but thanks again for this really instructive hint!
