Same problem...

[MacTheZazou]

@KayPure I think I got it to work by using the binary of ffmpeg built by BtbN : https://www.ffmpeg.org/download.html#build-windows

[axeldelafosse]

Hmm that's weird, I haven't seen this error. How did you install ffmpeg?

[chnoma]

I'm having the same issue here, I think

I'm on EndeavourOS, ffmpeg installed via pacman

[chnoma]

This looks like a problem with ni-stem, rather than stemgen to me, but line 106 of stem.py doesn't do an error check and it ends up finishing cleanly but no output.

[chnoma]

Here's a full log:
https://gist.github.com/chnoma/30f12bcc9446150395486a0d37f02522

Nothing is generated in the output folder

EDIT:

it was because I didn't have gpac installed it seems sorry :(

[axeldelafosse]

Hey @chnoma -- glad you found the issue.

The first one was because the input file didn't exists: input/wwh.1.flac: No such file or directory

And yeah the second one was because gpac wasn't installed. On Linux you need to install it yourself. It's in the docs but I'll add a callout to make sure that people don't miss it.

Closing to avoid growing this issue. Please feel free to report a new issue if you still experience one.
