To what extent are the set of intrinsics used for VP9/h265 decoding unreusable for AV1 decoding? My guess is that there is large amount of reusable intrinsics.

- muizelaar 8y agoIntrinsics aren't used. The decoding is generally done by a fixed function hardware block.
- nerdymanchild 8y agoIntrinsics must be used, how else is the hardware invoked?
- blattimwind 8y agoVideo decoders live somewhere in the general vicinity of the GPU and aren't invoked through CPU instructions. AFAIK.
- nerdymanchild 8y agoThis thread is about Intel processors, not GPUs
- fulafel 8y agoThe VP9/H.265 support in Intel chips is on the GPU side.
- nerdymanchild 8y agoThanks for the correction. I think my core point still holds without the intrinsics but I was mistaken on that point.
