How do you run mpv with nvidia driver installed?

[BugmanSpirit]

After installing the proprietary driver, is there some config to tell mpv to use the nvidia driver? Also, what config is recommended?

[paulcarroty]

hwdec=vdpau
vo=gpu

probably enough to use with NVidia GPU.

I am trying to use an all vulkan config. I built ffmpeg and mpv with vulkan enabled.

But why was vulkan disabled in the first place? Were people facing some issues?

• https://trac.ffmpeg.org/wiki/HWAccelIntro#Vulkan
• https://ffmpeg.org/ffmpeg-filters.html#Vulkan-Video-Filters

Would be nice to have it, will check later.

Update landed, got the next errors:

[vo/gpu-next/libplacebo] Failed initializing any SPIR-V compiler! Maybe libplacebo was built without support for either libshaderc or glslang?
[vo/gpu-next/libplacebo] Failed initializing vulkan device
[vo/gpu-next] Failed initializing any suitable GPU context!

[BugmanSpirit]

This looks like an issue with libplacebo, no? According to my understanding, libplacebo contains mpv algos that can be used by other programs as library. Is it necessary to build ffmpeg with libplacebo? Because mpv would not be relying on ffmpeg to apply shaders/filters that are native to itself.
Latest mpv has disabled the option for enabling shaderc but I do not see any way of telling it to enable glslang either. I'm also unable to enable Spirv-cross. I think issue is with mpv build only.

This is the reason: https://github.com/clearlinux-pkgs/libplacebo/blob/main/libplacebo.spec#L105C1-L106C1

Replacing this library and extracting this fixed mpv --gpu-context=waylandvk.
