It's not a collection of x86_64 instructions, it's an separate specialized core on Intel CPUs. https://en.wikipedia.org/wiki/Intel_Quick_Sync_Video#Hardwar... and AMD https://en.wikipedia.org/wiki/Video_Coding_Engine You need OS-dependent driver code to access it. Otherwise, if a decoder just uses x86_64 instructions, it's a software decoder.

Yeah, its called a VPU aka Video Processing Unit. If your hardware implements video decoding, they likely have licensed or designed their own VPU IP block.
