Phoronix: FFmpeg Git Continues Landing A Number Of Vulkan Video Enhancements

A number of Vulkan Video enhancements landed this week in FFmpeg Git thanks to open-source developer Lynne that has been advancing the Vulkan Video encode/decode capabilities in this widely-used multimedia library...

I've been trying to give Vulkan Video encode a try using cyanreg's FFmpeg repo, but I'm getting:
[h264_vulkan] Device does not support the VK_KHR_video_maintenance1 extension!

HW is RDNA3 with mesa 24.2.7.

Does anybody know when 'VK_KHR_video_maintenance1' is added to mesa, or am I doing something wrong?

Your Mesa is too old, KHR_video_maintenance1 is in Mesa 24.3 release.

Given that mesa 24.3.0 is about a week old, no wonder the distros didn't caught up yet

Yeah but if one runs ffmpeg git, then using mesa git (or at least latest upstream release) isn't that far-fechted

Yeah, true that.

Thanks, didn't catch that one!

While vulkan video is nice, I really hope that one day we see a "unified video decode" for linux that can work as a bridge so apps can implement hwdec across all forms of hardware.

Doesn't Vulkan itself serve that purpose? I.e. it's a unified interface that should work with any (decent / recent) hardware.

By the way, are there any news on pipewire support in ffmpeg? It seems to be taking forever. Not sure if those developers are still doing something or they are waiting for ffmpeg maintainers to review things?

Vulkan doesn't really make sense for things like arm/riscv sbcs where the video acceleration block is a seperate block from the gpu. Nor does it really make sense for dedicated accelerators (For instance the alveo MA35D) to use vulkan. It may be possible to implement this as a vulkan layer, I couldn't say for sure, it wouldn't really make a ton of sense.

none since august. The developers havent pushed a new patch set, Someone could take over. Not me, my RSI is too bad to do programming now.
