The ffnvcodec header of NixOS's custom ffmpeg is outdated.
a10f1aec1f/libavcodec/nvenc.h (L65-L67)

Also ffmpeg needs to be built with following options and patches for Nvidia to keep in line with our jellyfin-ffmpeg5:

The ffnvcodec header of NixOS's custom ffmpeg is outdated.

There are versions 10 and 11 in Nixpkgs (if I'm looking at the right thing), but the default is 9. https://search.nixos.org/packages?channel=22.05&from=0&size=50&sort=relevance&type=packages&query=nvenc

Should we override jellyfin-ffmpeg to use version 10?

I'll look into adding the other flags in the coming days.

We are using 11 in jellyfin-ffmpeg5, and the required minimum driver version is 470.

Also please add --disable-ptx-compression to build configs, which is required by our cuda tonemap filter.

I have created 3 PRs to Nixpkgs:

  1. https://github.com/NixOS/nixpkgs/pull/178276 - This is the simplest, least contentious one and should fix the root cause of failing NVENC transcoding.
  2. https://github.com/NixOS/nixpkgs/pull/178283 - HW decoding support
  3. https://github.com/NixOS/nixpkgs/pull/178278 - CUDA tonemap support

Thanks for your guidance. I understand that it sucks getting issue reports from people with "esoteric" setups 😅

I have created 3 PRs to Nixpkgs:

  1. jellyfin-ffmpeg: bump nv-codec-headers to v11 NixOS/nixpkgs#178276 - This is the simplest, least contentious one and should fix the root cause of failing NVENC transcoding.
  2. ffmpeg-full: add NVDEC support NixOS/nixpkgs#178283 - HW decoding support
  3. ffmpeg-full: add cuda features, jellyfin-ffmpeg: fix CUDA tonemap NixOS/nixpkgs#178278 - CUDA tonemap support

Thanks for your guidance. I understand that it sucks getting issue reports from people with "esoteric" setups 😅

Thanks! Any chance you can also add --enable-opencl, which is required for Intel and AMD to do HW tonemap.
