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... [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.

Nixpkgs is a collection of packages for the Nix package manager. It is periodically built and tested by the Hydra build daemon as so-called channels. To get channel information via git, add nixpkgs-channels as a remote:
% git remote add channels https://github.com/NixOS/nixpkgs-channels.git
For stability and maximum binary package support, it is recommended to maintain
custom changes on top of one of the channels, e.g. nixos-19.03 for the latest
release and nixos-unstable for the latest successful build of master:
% git remote update channels
% git rebase channels/nixos-19.03
For pull requests, please rebase onto nixpkgs master.
NixOS Linux distribution source code is located inside
nixos/ folder.
