Pause and resume live video with latest frames without affecting the sink

[vk_gst]

Corrected pseudo code: 


while True:
   # apply gltransformation always - control reaches here when imagefreeze
is inserted, however no effect on displayed video., without imagefreeze, the
effects work.

   # if user_input == 1
      # set drop-probability=1 for element identity to pause the video
      # insert imagefreeze in pipeline
   #if user_input == 2
      # set drop-probability=0 for element identity to replay the video
     # delete imagefreeze from pipeline
