Downloads marked as failed when writing a thumbnail (mutagen missing)

[jonfairbanks]

When passing in options to embed a thumbnail, the downloads end up being marked as failed due to mutagen missing in the Docker image.

Configured options: { "writethumbnail":true, "postprocessors":[ {"key":"FFmpegMetadata","add_metadata":"True"}, {"key":"EmbedThumbnail"} ] }

which docker image are you using?

I am using ghcr.io/alexta69/metube.

Hi All,

I encountered an error: ERROR: Postprocessing: module mutagen was not found. Please install using `python3 -m pip install mutagen

Did a search on metube project page and found this issue and think its the same issue I was dealing with. I have a workaround that worked for me but YMMV.

root@nasa:~# docker exec -it metube bash
OCI runtime exec failed: exec failed: unable to start container process: exec: "bash": executable file not found in $PATH: unknown
root@nasa:~# docker exec -it metube sh
/app # pip install mutagen

tldr:

docker exec -it metube sh
pip install mutagen
pip install --upgrade pip
exit
docker restart metube

and retry failed download

its not pretty or perfect but may help some others out there. perhaps all the author needs to do is update the libraries of the base docker image/Dockerfile.

btw, thanks to the author for such a great project. Ive been using it for years now.

If helpful, I opened up pull request https://github.com/alexta69/metube/pull/667 to include mutagen in the Pipfile.
