I also encountered this in fresh Trusty install. The bug here isn't (just) missing dependency. There are always going to be codecs that aren't (can't be legally) supported out of the box.
The bug is crappy reporting of the issue in Parole. Showing on what source code line issue is noticed instead of reporting what the issue actually is and what user can do to fix it: i.e. "Support for codec XYZ hasn't been installed (install package ABC to have it)". Gstreamer has support for finding that out and it's done by other media players (e.g. in gstreamer based players already in Maemo devices from previous decade). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1278089 Title: Parole reports "Gstreamer backend error, could not initialise supporting library" To manage notifications about this bug go to: https://bugs.launchpad.net/parole/+bug/1278089/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
