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

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

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

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.
