Sorry if I'm misunderstanding your comment's implication. But this is not hardware decoding. This is software decoding on the GPU.

NVIDIA for example has specialized (en/de)-coding hardware on their GPUs, which is different. And even that works together with their GPGPU Cuda cores.

No, the entire point of those vulkan extensions is to use the hardware-accelerated video processing units. You can use computer shaders for software decoding on the GPU, there is no need for special extensions to do that. AMD and Intel have specialized encoding/decoding hw too.

All three big vendors (Nvidia, AMD, Intel) and also bunch of ARM SoC vendors do have specialized blocks in their graphic solution whose only purpose is to decode and encode specific codec profiles. It is hardware decoding, not decoding on GPU.
