Comment 17 for bug 1278089

I upgraded to 14.04 LTS, and was switched back to Parole which does not work. I had previously uninstalled it and switched to VLC which pretty well always works with anything.

I have tried the following so far to get rid of this error:

parole --xv false
no affect (not this bug there is a decent message that indicates this as a fix)
sudo apt-get install xubuntu-restricted-extras
no affect
sudo apt-get install gstreamer1.0-plugins-base
already installed no affect
sudo apt-get install gstreamer1.0-pulseaudio
not installed still no affect I am trying to play a .mp4

Tried closing and reopening Parole, so one of the above steps fixed it.

Got a different error
GStreamer Error
Unable to load "playbin" plugin, check your GStreamer installation.
Parole Media Player cannot start.

Put gstreamer1.0-plugins-base back
Got unable to load "autoaudiosink"

 sudo apt-get install gstreamer1.0-plugins-bad gstreamer1.0-plugins-bad-faad

repeat of error Got unable to load "autoaudiosink"

installed gstreamer1.0-plugins-good libcheese-gtk23 libcheese7
WORKING - again

Not able to recreate the "Gstreamer backend error, could not initialise supporting library"

(A really vague horrible error message - sums up Parole for me no idea why it is the default)
