How to add ffmpeg in a flask - python project on railway?
Hi, i have the next issue:
I like to process an audio (type bytes) and I have this error:
warn("Couldn't find ffmpeg or avconv - defaulting to ffmpeg, but may not work", RuntimeWarning)
anybody know how to fix it?

add a nixpacks.toml file with this in it to your project
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
