How to build mpv for linux hwdec=nvdec / gpu-api=opengl ?

[louisefp]

Hi,

I'm trying to build mpv for linux (rocky) with nvdec / opengl.
What dependencies are required?
What flags must be enabled?

When I test my build I always have the following errors.

[vo/gpu-next] Failed initializing any suitable GPU context!
Error opening/initializing the selected video_out (--vo) device.

./mpv --vo=help
Available video outputs:
gpu-next Video output based on libplacebo
gpu Shader-based GPU Renderer
libmpv render API for libmpv
null Null video output
image Write video frames to image files
tct true-color terminals
kitty Kitty terminal graphics protocol

./mpv --gpu-api=help
Available GPU APIs:
auto

Available GPU APIs and contexts:
auto auto

Thank you,
Louise
