Ubuntu – Ubuntu 14.04, problem when install gstreamer1.0-libav, unmet dependencies

14.04dependenciesgstreamersoftware installation

Suddenly my Ubuntu stopped playing video. When I open a video, the player suggests that I install gstreamer1.0-libav. However, it fails to install.

I tried installing it manually, here is the error message:

$ sudo apt-get install gstreamer1.0-libav
Reading package lists... Done

The following information may help to resolve the situation:

 gstreamer1.0-libav : Depends: libavcodec54 (>= 6:9.1-1) but it is not going to be installed or
                               libavcodec-extra-54 (>= 6:9.13) but it is not going to be installed
                      Depends: libavformat54 (>= 6:9.1-1) but it is not going to be installed
