In previous versions of Ubuntu, playing MIDI files "just worked"; Totem would open and play them. However, ever since I upgraded to Saucy it can no longer do this; instead it generates an error about a missing plugin. I've heard of some command line workarounds, but is there any way to make it just work as it did in earlier versions?
Totem plays MIDI files on my system (Ubuntu 14.04) since I installed the package
fluid-soundfont-gm. The package requires about 150 MB disk space.
The VideoLAN wiki https://wiki.videolan.org/Midi and this forum post http://ubuntuforums.org/showthread.php?t=2146538&page=2 (answer by
rubo77) recommend installing the package
vlc-plugin-fluidsynth. The VLC package has
fluid-soundfont-gm as a dependency, which is how I found
Have you installed the gstreamer0.10-codecs-bad package in the software centre which handles midi files ? Generally on a new install I add the gstreamer good, bad and ugly codecs so that Totem can play almost everything I throw at it...
