Building FFmpeg with extra functionality. To install the maximum amount of functionality offered by Nix binary repositories, you may install ffmpeg like the following.

environment.systemPackages = [
  pkgs.ffmpeg-full
];

More codecs

Adding more functionality to ffmpeg is possible, but it will require compiling on your local system.

The Fraunhofer FDK AAC audio codec is said to give superior compression and audio quality to other AAC codecs. To install

environment.systemPackages = [
  (pkgs.ffmpeg-full.override { withUnfree = true; })
];

It is possible to add support for more than one feature at a time. To add FDK AAC AND OpenGL rendering support

environment.systemPackages = [
  (pkgs.ffmpeg-full.override { withUnfree = true; withOpenGL = true; })
  ];

Using the pattern shown in previous examples, we can set the following options as true (enabled):

withUnfree # Currently only FDK AAC Codec withOpenGL # OpenGL rendering support withRmtp # RMTP support withTensorflow # Tensorflow dnn backend support

Speeding up install

It's possible to speed up the install. After compiling is finished, a series of generic checks are run. To skip these checks, we need to set doCheck to false. Here is an example of adding FDK AAC support, and skipping post build checks.

environment.systemPackages = [
  ((pkgs.ffmpeg-full.override { withUnfree = true; }).overrideAttrs (_: { doCheck = false; }))
];
