this runs fine for me on x86_64-linux (wayland/sway), but the new svt-avt package input added in this patch breaks the aarch64-linux build in a new way:

$ nix build '.#legacyPackages.aarch64-linux.handbrake'
error: Package ‘svt-av1-1.4.1’ in /nix/store/1w97dryirwh60407sg97x521m0aisln4-source/pkgs/tools/video/svt-av1/default.nix:31 is marked as broken, refusing to evaluate.

ffmpeg-full special-cases a few dependencies, presumably to work around platform-specific issues like this:

ffmpeg-full = callPackage ../development/libraries/ffmpeg-full {
    svt-av1 = if stdenv.isAarch64 then null else svt-av1;
    rtmpdump = null; # Prefer the built-in RTMP implementation
    # The following need to be fixed on Darwin
    libjack2 = if stdenv.isDarwin then null else libjack2;
    libmodplug = if stdenv.isDarwin then null else libmodplug;
    libmfx = if stdenv.isDarwin then null else intel-media-sdk;
    libpulseaudio = if stdenv.isDarwin then null else libpulseaudio;
    samba = if stdenv.isDarwin then null else samba;
    inherit (darwin.apple_sdk.frameworks)
      Cocoa CoreServices CoreAudio AVFoundation MediaToolbox
      VideoDecodeAcceleration VideoToolbox;
  };

i guess if you want to ditch it maybe you have to replicate some of that?

The problem here is that svt-av1 is a dependency of handbrake, not ffmpeg. So setting svt-av1 to null would result in a failing build on aarch64. I haven't been able to figure out if there is a way to build handbrake 1.6.1 without svt-av1.

If the package now requires svt-avt and that does not work on aarch64-linux that is unfortunate but I don't think we can do anything here unless we find some patch upstream or ask them for help.

I agree with Sandro here.

@uninsane svt-av1 was marked as broken 2 years ago, can you try if a new version fixed the issue on aarch64 and nixpkgs just forgot to set broken to false? I don't have aarch64 hardware, so i can't test.

Cross compiling svt-av1 for aarch64 works just fine.

❯ export NIXPKGS_ALLOW_BROKEN=1
❯ nix build nixos\#pkgsCross.aarch64-multiplatform.svt-av1 --impure --print-out-paths
/nix/store/n0kvp195xn02brcsbq7ga3y0cnavwbfh-svt-av1-aarch64-unknown-linux-gnu-1.4.1

It think that you can just remove this:

darwin aarch64 is still broken but that might be related to the apple SDK. It didn't work before so that is fine
