As I understand, rhythmbox was using a GStreamer plugin to edit m4a tags, named qtdemux (for "Quick Time demuxer")
But this plugin disappeared(?) since Ubuntu Precise. It appears in Ubuntu Lucid [1], but is not anymore in Ubuntu Trusty [2] Lucid has gstreamer0.10-plugins-good 0.10.21-1ubuntu2 [3] Trusty has gstreamer0.10-plugins-good 0.10.31-3+nmu1ubuntu5 [4] [1] http://packages.ubuntu.com/search?suite=lucid&arch=any&mode=filename&searchon=contents&keywords=qtdemux [2] http://packages.ubuntu.com/search?suite=trusty&arch=any&mode=filename&searchon=contents&keywords=qtdemux [3] http://packages.ubuntu.com/lucid/gstreamer0.10-plugins-good [4] http://packages.ubuntu.com/trusty/gstreamer0.10-plugins-good -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1340907 Title: cannot edit tags in m4a files To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/rhythmbox/+bug/1340907/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
