add a nixpacks.toml file with this in it to your project
[phases.setup]
nixPkgs = ['...', 'ffmpeg']
[phases.setup]
nixPkgs = ['...', 'ffmpeg']

Thank you for helping on this ! Now ffmpeg seems to be correctly installed. However I'm getting this error : "json.decoder.JSONDecodeError: Expecting value: line 1 column 1 (char 0)" According to this : https://github.com/jiaaro/pydub/issues/450 It is caused by having a customize output location for ffmpeg which Pydub does not expect. I think there is a way to point to Pydub where is installed ffmpeg. Do you have any idea where ffmpeg could be installed ? Maybe I could find it using CLI but am very new to railway and I'm not sure how to use it 🙂 Thank youu

ffmpeg would be installed somewhere in one of the folders listed in the PATH environment variable, if the library can't pick this up then it's a problem with the library and it would likely be much easier to use a library with no such issues

Ok then ! thank you for answering I solved the issue using this instead in the nixpacks.toml file: [phases.setup] nixPkgs = ["...", "jellyfin-ffmpeg"]

well that's certainly an odd fix
