fakesink is by default not synced to the clock. So it takes buffers
as fast as it can handle them. use the sync=1 property to sync to the
clock and the duration of the pipeline will be 50s.

gst-launch-0.10 -v videotestsrc num_buffers=50 ! video/x-raw-rgb,
framerate=\(fraction\)1/1 ! fakesink sync=1
