Zink Seeing VA-API Video Acceleration Implemented Over Vulkan Video

Anyway, is this gonna be limited to there formats officially supported by Vulkan, or could they make some Mesa-specific extensions to support more formats?

it's possible they could extend it, but what codecs are you thinking about that would be useful here?

How does that work with energy-saving measures? AFAIK, the video part of the chip is very often independent of the 3D part. So, you can watch a full-screen video without enabling the 3D part of a GPU. Can Vulkan work in that way?

Sure.

I really hope hasvk implements vulkan video, intel-vaapi-driver is broken now, unusable in chrome, unusable in wayland. these devices are effectively nuttered now. hasvk + zink could bring these back to usable

Yes, nvidia has vulkan video, I meant Firefox adding vk video will take forever.
Vaapi drivers for Nvidia aren't that good afaik (I have hybrid, I use amdgpu for browsers anyway) I mean as a long term solution etc.

My mistake then, sorry.

This might be the long-term solution for Nvidia video acceleration on Firefox/Chromium? Given they'll probably take a decade to support Vulkan video themselves ╮⁠(⁠＾⁠▽⁠＾⁠)⁠╭

I sure hope so because it's one of the few major problems NVIDIA users have left for general desktop use.

He's talking about video decode acceleration, not graphics.

I know, right now the status quo is that you get graphics acceleration with Zink but not video acceleration. Implementing VAAPI on top of Vulkan Video should hopefully fix that (in the future at least, I don't know if Nvk and the Apple Silicon Vulkan drivers support Vulkan Video yet, but they surely will in the future).

NVIDIA already supports Vulkan Video. Hardware video decode also works on Firefox on NVIDIA with nvidia-vaapi-driver that implemented VAAPI on top of NVDEC.

This is a cool idea but I imagine it will always be more power efficient to use dedicated APIs as they can use on-device decoders.

vulkan video uses the HW blocks, so this does too
