Set the sink's sync property to false, and let the video play. Then 
check out the output of gst-launch. It prints how long that pipeline 
ran. With sync=false the sink will output the frames as fast as 
possible. So if for example gst-launch says "Execution ended after 
0:00:26.999483319" but the video is 30 seconds long, you have a problem.
