Describe the Bug
AV1 encoding doesn’t work. Sunshine falls back to CPU-based H.264 encoding because it can’t find GPU support for H.264. Tested on both Wayland and X11. My GPU only supports AV1 encoding
vainfo output:
vainfo: VA-API version: 1.22 (libva 2.22.0)
vainfo: Driver version: Mesa Gallium driver 25.1.9 for AMD Radeon Graphics (radeonsi, gfx1200, LLVM 20.1.8, DRM 3.64, 6.17.8-200.fc42.x86_64)
vainfo: Supported profile and entrypoints
VAProfileJPEGBaseline : VAEntrypointVLD
VAProfileVP9Profile0 : VAEntrypointVLD
VAProfileVP9Profile2 : VAEntrypointVLD
VAProfileAV1Profile0 : VAEntrypointVLD
VAProfileAV1Profile0 : VAEntrypointEncSlice
VAProfileNone : VAEntrypointVideoProcExpected Behavior
Setting both the client and the server to prefer AV1 should result in using the GPU AV1 encoder for video.
