>From what I understand this is caused by the removal of ffmpeg, replaced by libav (a fork) : http://askubuntu.com/questions/432542/is-ffmpeg- missing-from-the-official-repositories-in-14-04
For gmusicbrowser, the problem is that is uses gstreamer 0.10 which uses gstreamer0.10-ffmpeg to decode mpc (and lossless m4a too, probably more) which doesn't compile with libav, so it has been removed (https://bugs.launchpad.net/ubuntu/+source/gallery-app/+bug/1254033) as gstreamer 0.10 is deprecated in favor of 1.0 I've installed ffmpeg and gstreamer0.10-ffmpeg via the ppa mentioned in the askubuntu question above, and it does fix the playing of mpc and lossless m4a in gmusicbrowser, the ppa also contains a vlc that plays mpc. Of course it is not a proper fix -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1310554 Title: Regression: breaks mpc decoding with some players To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/libmpc/+bug/1310554/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
