Hi It seems this whole situation is starting to get a little bit more complex. VDPAU hasn’t been updated for a while, and is now missing HEVC 10-bit and VP8/VP9 support. It seems this is never going to be updated given that NVIDIA now have nvdec. The libva-vdpau-driver project gave us a VA-API im…

Just to reinforce this point - the GLX interop was horrible and had bad performance characteristics, so everyone moved to the EGL interop as quickly as they could. If you leave mpv default config alone, it should automatically prefer x11egl and vaapi at this point - you’d only use GLX if you forced…

Not on AMD. mpv checks the existence of GL_NV_vdpau_interop to decide between GLX and EGL. And well, the AMD driver implements GL_NV_vdpau_interop, so GLX gets chosen and loading VAAPI fails. There’s a PR open on mpv’s github to change this and always prefer EGL (forcing Nvidia VDPAU users to speci…

You are right. I forgot about that PR - it’s been a long time and I don’t think it’s on anyone’s radar anymore. My personal opinion is we should flip it, given how VDPAU is less and less useful. But on the other hand, I’m surprised the AMD driver is still claiming to support vdpau. Everyone uses v…

give a try to qmplay2 …it supporst vdpau and cuvid decoding …

Hey, @NVIDIA , any update on this? I’ve noticed a new version of the VDPAU library with VP9 support, which is nice, although no version of the NVIDIA driver actually supports that yet. Regards elFarto

Is there any update on this? Firefox 80 now has support for VA-API, although I can’t check if it’s actually working.

Now that GBM has been added to the 495 drivers, would we be seeing Wayland support for VDPAU as well, or VA-API for Nvidia cards? It seems like quite a major not to have any hardware decoding capabilities in any major browser. NVDEC also still has the annoying behavior of switching the entire GPU to…

Funny you should bring this up. I’ve just been taking a look into it again now that I’m on 495. In theory the only part left to prove works is exporting a buffer from CUDA that can be imported via the DMA-BUF mechanism. CUDA supports exporting an fd, but as to if that’ll work with eglCreateImage I’m…

Quick update, it’s working: [Screenshot_2021-11-13_15-22-46] Unfortunately it’s only working for around 64 frames and then crashes, so I’m clearly running out of some resource, but things are looking good.

What's the situation with vdpau/vaapi/nvdec?

Any update on this? Seems Firefox is getting closer[1] to supporting VA-API.
