The error message is certainly confusing but I'm afraid you cannot set attachments in MP4 files in general. Attachments are in fact only implemented for Matroska files and I don't think the MP4 format itself supports attachments anyways. If you would like to set a cover, just set it as tag value. The cover should then also be recognized by other applications.

By the way, there's already https://github.com/Martchus/tageditor/issues/55 which is about streamlining adding covers to Matroska files so one could also add a cover to Matroska file by setting the tag value and would not have to use different commands depending on the file format. However, I have not implemented it yet.

can give me an Command line example?

Martchus commented 3 years ago

Something like tageditor set cover=/the/cover.jpg -f /the/file.mp4 should work. Also checkout --help and the README.
