This fixes #67780. Currently, using `mpv --hwdec=nvdec --msg-level=vd=debug` on NVIDIA results in: ``` [vd] Opening decoder hevc [vd] Looking at hwdec hevc-nvdec... Cannot load libcuda.so.1 [vd] Could not create device. [vd] No hardware decoding available for this codec. ``` With just mpv patched, ffmpeg cannot load libnvcuvid.so.1: ``` [vd] Opening decoder hevc [vd] Looking at hwdec hevc-nvdec... [vd] Trying hardware decoding via hevc-nvdec. [vd] Selected codec: hevc (HEVC (High Efficiency Video Coding)) [vd] Pixel formats supported by decoder: vaapi_vld cuda yuv420p10le [vd] Codec profile: Main 10 (0x2) [vd] Requesting pixfmt 'cuda' from decoder. [ffmpeg/video] hevc: Cannot load libnvcuvid.so.1 [ffmpeg/video] hevc: Failed loading nvcuvid. [ffmpeg/video] hevc: Failed setup for format cuda: hwaccel initialisation returned error. ``` With both mpv and ffmpeg patched, it works: ``` [vd] Opening decoder hevc [vd] Looking at hwdec hevc-nvdec...
