Thanks for your reply. Yes, I was able to extract the embedded cover using ffmpeg:
$ ffmpeg -i "song.m4a" -an -vcodec copy test.png The output image is correct. However, when I run the `totem-video-thumbnailer` command, it fails: $ /usr/bin/totem-video-thumbnailer -v "song.m4a" test.png Output: TotemVideoThumbnailer-Message: 14:33:51.040: Initialised libraries, about to create video widget TotemVideoThumbnailer-Message: 14:33:51.051: setting URI file:///home/secon/Music/song.m4a TotemVideoThumbnailer-Message: 14:33:51.051: Video widget created TotemVideoThumbnailer-Message: 14:33:51.051: About to open video file totem-video-thumbnailer couldn't open file 'song.m4a' -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2111560 Title: Nautilus does not show embedded album art thumbnails for .m4a files To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nautilus/+bug/2111560/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
