I have tried
gpu-context=wayland
hwdec=vdpau
vo=gpu
but mpv crashes with floating point exception (core dumped). Is it impossible? If not, what is the correct conf?
I chose “proprietary drivers” at the installation, so Nvidia driver 515.65.01 has been automatically installed.
Nothing to do with wayland or xorg…
mpv --gpu-context=help
mpv --hwdec=help
mpv --vo=help
You might need cuda.
But cuda seems to be 4.1GB. Do I really need to install this just to enable hardware video decoding? The outputs of the three commands are below.

you need no cuda extra install
In your case, is it Wayland, not X11? I have tried all the three you said (did not expect the third one would work, because cuda is not installed), and all three crashed with the same message.
Xlib: extension "NV-GLX" missing on display ":0".
Xlib: extension "NV-GLX" missing on display ":0".
zsh: floating point exception (core dumped)
The video is just a typical 1080p 29fps h264 video.
Is that a system with 2 graphics cards?
No, only one RTX2060 card.
By the way, I logged in to X11 and that conf worked without crashing. Are you sure that you are using Wayland?
PS: If it is of any worth, there are two monitors.
i use x11.
wayland +nvidia= not a good solution
Well… After some web searching, I have found
I think to remember that Nvidia doesnt support VAAPI at all. There is however a wrapper that might work, or not. For VDPAU, it requires X11 to run and wont work on wayland or even xwayland.
If Nvidia’s hardware decoding does not work under Wayland, I wish Arch MPV page had mentioned the fact so that we would not have wasted time.
It’s a Wiki, so you’re invited to add that important piece of information yourself.
