@Nille, curaga:
So its possible, but developers consider its efficiency to be inadequate.
Which is pretty much blind-sighted, because CPU could do something else. The whole video acceleration is about "offloading". You can?t easily add another "50$" CPU into the system, but you CAN put another GPU into PCIe.
OP should look into HSA, maybe.

AMD is for encoding the worst case btw. its impossible for an normal user or developer to get the SDK for use the Hardware encoder in the radeon products.

Its easier and cheaper to replace the CPU or re-encode the video the asic in the gpu like quiksync or nvidias cuda encoder ( that has nothing todo with cuda its use only the name for marketing and use like everyone else an hardware chip for this )

Used 57xx+ cost around 50$ now. If PM were right, they would use minimal wattage and there is already OpenCL work done.
I am pretty sure one could easily implement video decode backend for OpenCL stack by replacing existant codecs codepaths and optimizing them.
IMHO its all possible, but I don? t claim anyone is interested in that yet.

That's completely wrong. Better look at:
It was never emulated via OpenCL. You can do that maybe for very simple codes but that would be never a good idea. xvba crashed very hard in the beginning with my hd 3450, then i got rid of it and got a hd 4550. the hd 5670 has basically a similar uvd part. Only hd 6000+ has got UVD 3.
