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!
