Issue with AtomicParsley and Thumnnail Embed

[Shamus03]

I'm getting this error when running youtube-dl --format=worst --embed-thumbnail URL:

[atomicparsley] Adding thumbnail to "Video.3gp"

I ran brew install AtomicParsley and it works fine alone, but it looks like a file that doesn't exist is trying to be referenced. Any help on fixing this error?

It won't fail in the next version, but the AtomicParsley can't embed the thumbnail in 3gp files, you may want to run youtube-dl test:youtube -f worst[ext=mp4] --embed-thumbnail instead.

For future reports, please post the full output you get with the --verbose option, it gives us important information.

Is --embed-audio supposed to convert videos to only audio?

Yes, as the help says: Embed thumbnail in the audio as cover art. If you want to make it also work for video, please open a new issue.
