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.

Intrinsics aren't used. The decoding is generally done by a fixed function hardware block.

[nerdymanchild]

Intrinsics must be used, how else is the hardware invoked?

[blattimwind]

Video decoders live somewhere in the general vicinity of the GPU and aren't invoked through CPU instructions. AFAIK.

This thread is about Intel processors, not GPUs

[fulafel]

The VP9/H.265 support in Intel chips is on the GPU side.

Thanks for the correction. I think my core point still holds without the intrinsics but I was mistaken on that point.
