Tried the following from http://doc.qt.io/qt-5/qml-qtmultimed...r.html#details

Qt Code: 
  1. import QtQuick 2.4
  2. import QtQuick.Window 2.2
  3. import QtMultimedia 5.0
  4.  
  5. Window
  6. {
  7.     visible: true
  8.     height: 1000
  9.     width: 1000
  10.  
  11.  
  12.     MediaPlayer {
  13.         id: mediaplayer
  14.         source: "/home/****/template/v1.avi"
  15.     }
  16.  
  17.     VideoOutput {
  18.         anchors.fill: parent
  19.         source: mediaplayer
  20.     }
  21.  
  22.     MouseArea {
  23.         id: playArea
  24.         anchors.fill: parent
  25.         onPressed: mediaplayer.play();
  26.     }
  27. }
To copy to clipboard, switch view to plain text mode 

on Ubuntu 14.04.2 LTS \n \l with GStreamer Core Library version 0.10.36

This gives the error shown in title on click.
I have confirmed that the file exists.

What else can be done now?
