- nerdymanchild 9y agoIntrinsics must be used, how else is the hardware invoked?
- blattimwind 9y agoVideo decoders live somewhere in the general vicinity of the GPU and aren't invoked through CPU instructions. AFAIK.
- nerdymanchild 9y agoThis thread is about Intel processors, not GPUs
- fulafel 9y agoThe VP9/H.265 support in Intel chips is on the GPU side.
- nerdymanchild 9y agoThanks for the correction. I think my core point still holds without the intrinsics but I was mistaken on that point.
