NVIDIA doesn't support VA-API natively, and neither libva-vdpau-driver
nor libva-nvidia-driver support encoding[1] (required by obs-studio).

- VDPAU is a decoding-only API thus pointless for screen recording
- NVENC uses CUDA thus requires nv-sglrun (from libc6-shim) on FreeBSD
- Vulkan Video encoding[2] is not supported by obs-studio yet

Maybe double-check https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=264027
I don't have an NVIDIA GPU to test if it hasn't regressed since then.
However, if mpv with --hwdec=nvdec (requires nv-sglrun) still works then
try bisecting obs-studio updates.
