Experimental RADV Vulkan Video Decoding For VP9

edxposed Interesting, thx!

And when are browsers going to use this?!

Firefox is not a possibility at the moment, and as for Chromium, everything depends on the decision of the Chrome Media Team, someone who revealed a few weeks ago that they have no plans for VulkanVideo, considering the existing Direct3D11VD/VideoToolboxVD/MediaCodecVD/ VaapiVD/v4l2VD is good enough
As far as I know, VulkanVideo is still lacking video processing, so it can't use fixed-function hardware to perform scaling, tone mapping, etc. This means that hardware DRM cannot be supported and mobile device battery life suffers, which is probably why they don't want to implement it

wish I could test this, but polaris -_-

Looking forward to AV1 encoder code in radv + ffmpeg and then OBS using that. VAAPI takes forever to materialize.

The old me would have thought this is a waste of time, especially when Khronos has started work for VP9 and AV1 (and finished with h.254/h.265). Today I just believe that this experimental code is good practice to implement the future code that will replace this experimental code, or maybe just maybe.. reuse it.

That's great!
I hope to see AV1 supported this year too.
I wonder WTF is Khronos waiting for to make the VP9 and AV1 official?

They are banging away at it, so you can expect it later this year, since AV1 hardware decoders are now shipping in the newest GPUs.

https://airlied.blogspot.com/2023/02...-anv-radv.html there is talked about AV1 and H265. "The radv h264/h265 support has been merged to mesa main branch. It is still behind RADV_PERFTEST=video_decode flag, and should work for basics from VI/GFX8+. It still has not passed all the CTS tests."

Av1 is not merged yet.

Also note that Vulkan only has an extension for h.264 and h.265. anything else is "unofficial"

Great, but more importantly does it support H.264 and AV1?
