Yes, you are right, it is not a MP3 file. My main problem wasn't that it doesn't work, but the lack of debugging options.
It would be nice if rhythmbox could display the tags of webm containers with opus audio (like id3info), or if it would somehow tell you that test.mp3 is not a valid mp3 file. I also opened a bug in youtube-dl, but it got closed (IMHO completely unjustified). https://github.com/ytdl-org/youtube-dl/issues/21785 ** Bug watch added: github.com/ytdl-org/youtube-dl/issues #21785 https://github.com/ytdl-org/youtube-dl/issues/21785 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1836459 Title: Rythmbox fails to read mp3 tags To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/rhythmbox/+bug/1836459/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
