Title:
  Gnome videos (Totem) cannot play mp4, snap store installer broken

Status in gstreamer1.0 package in Ubuntu:
  Confirmed
Status in snapd package in Ubuntu:
  Confirmed
Status in totem package in Ubuntu:
  Confirmed

Bug description:
  My attempts to get it to work with gnome video (Totem) fail due to a
  missing decoder:

  When I start the video with `xdg-open some.mp4`, in a window over the
  first frame of the video player I get a popup that says:

  ```
  Unable to play the file
  meta/x-gst-fourcc-mett decoder is required to play the file, but is not installed.

  Cancel | Find in Ubuntu Software
  ```

  When I click "Find in Ubuntu Software",  another window is opened with a spinning circle which runs indefinitely without finding anything. The process that is spawns is this:
  ```
  /usr/bin/gstreamer-codec-install --interaction=hide-confirm-search --desktop-id=org.gnome.Totem.desktop --startup-notification-id=_TIME1227877508 gstreamer|1.0|totem|meta/x-gst-fourcc-mett decoder|decoder-meta/x-gst-fourcc-mett
  ```
  This process, by the way, does not get cleaned up when the parent windows are closed - manual cleanup is required.

  It appears that gstreamer shouldn't even require installing codecs,
  since gst-play-1.0 is fully capable of playing the mp4:

  ```
  gst-play-1.0 some.mp4
  ```

  Other details:
  - all of the totem's `Recommends` and `Suggests` packages installed.
  - ffplay can play this mp4
  - vlc can play this mp4
