NVIDIA VA-API Driver 0.0.9 Released With YUV444 Support

[tildearrow]

AMD's AMF does 8bit 444 in OBS , no clue in anything else though .

On which card specifically? From what I've heard, only VCE 2.0 supports 4:4:4, and it's intra-frame only.

What's the story with AV1 VAAPI encoder for AMD by the way?

Doesn't look like it exists even for RDNA 3.

6800xt here, Dont know if the 7xxx series has it through the AMF driver. It is intra looking in the settings.

Not seen amything regards it for an age to be frank.

Is this the only forum that don't do multi quoting ?

My problem with this is that decoding from cpu has lower energy usage compared to decoding from gpu: https://github.com/elFarto/nvidia-va...iver/issues/74
Using nvdec really doesn't make sense since decoding 1080p and 1140p videos on cpu has lower energy consumption overall.

I wish Nvidia had a native vaapi support or this project were supporting vdpau instead of nvdec. I guess this is only useful if you are decoding 4k videos all the time then it makes sense to use gpu decoding in terms of saving some energy consumption.

Not the mention cpu decoding at the moment more stable than this implementation.

I'd guess thats because Nvidia clocked the 3000 series so aggressively :/. And also the firefox video player may not be as efficient as it could be.

My old AMD 7950 also had a weird, unecessarily high p state it would go into when decoding video. But it wasnt linux specific, and it also wasnt an issue because it wasnt a 350 Watt GPU.

I'm observing this behaviour with my mobile 1060 card. The problem is probably related to nvdec. Using nvdec instead of vdpau on mpv when decoding also increases overall energy consumption. So its not just firefox.

You can do the multi quoting "manually".

Supporting VDPAU doesn't make sense nowadays as it needs a native X.org/X11 system to work. That means it doesn't work in a Waylandsession while nvdec does. So to allow GPU decoding on linux for Nvidia GPU'S in the future there must be another solution.VAAPI,nvdec or Vulkan Video would do the job.

Another problem is the missing support for both videoencoding and decoding in most linuxapps: Browsers (Webrtc), Elektron Apps etc. Also Videoencoding and decoding can cause a massive load on the CPU on lowerend (and older) Hardware. GPU offloading is very important in such a case.

You are right. Long term solution cannot be vdpau. You're also right about videoecoding.
At this point Nvidia should really fix their nvdec since as far as I can remember I did not observe the same increased power consumption when decoding and encoding in Windows. I don't know how they are handling their Windows video decoding and encoding but we need something like that.
