Okay I've figured it out. If you remove the PPA for Openshot from the Software Sources, and then uninstall every package listed under "ffmpeg" in Synaptic Package Manager and also uninstall Openshot, then reinstall the packages listed under "ffmpeg", then Totem will work again.
Just uninstalling Openshot was not enough. I think this is because Openshot has its own ffmpeg and subsequent libraries that it installs and makes Totem and other video players not work. -- Totem unable to play videos after installing Openshot https://bugs.launchpad.net/bugs/489832 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
