Phoronix: Samsung Developer Posts VA-API Support For Nouveau

While the open-source NVIDIA (Nouveau) driver has supported Gallium3D's VDPAU state tracker, there is a new set of patches for also being able to benefit from the VA-API state tracker for video acceleration...

Is this enough for VA-API to work well on nouveau?

Hmm, I wonder if Samsung's working on a Tegra-based system that needs VAAPI-based acceleration. Don't the recent tegra chips mostly use nouveau for their graphics drivers?

Even if they are, Tegra K1 (and fairly sure Tegra X1) don't include the desktop GPU video decoding engines, it's separate from the GPU "device" there.

imirkin would using va-api work around https://bugs.freedesktop.org/show_bug.cgi?id=76173 (vdpau GL_interop not working)?

And awesome work on nouveau to all! It works beautifully...

Thanks,

Highly unlikely, but... who knows. (Is there a va-api GL interop?) I have no idea what causes that issue, nor the inclination to figure it out -- just use mplayer, that works great.

Not that I'm complaining about this contribution, but I'd much rather see Samsung employees focus on getting Mali to work properly under linux with their own exynos chips.

Maybe Nvidia developers will be posting that patch.

Maybe Nvidia developers will be posting that patch.

It would be a nice work around for any legal problems.
Or maybe Samsung is thinking about replacing mali in favor for nvidia nouveau, as the current things they are working on definitely needs some good open source drivers (GearVR for instance, amazed that it even works like it does right now).
But actually va-api is about bitstream en/decoding, for which samsung already introduced memory-to-memory video4linux devices back in kernel 2.something?
