 You made my day, Vinod. Thank you so much. 

Actually, I use glsinkbin as well. The fault value of its sync is true.I do not know why the pipeline did not work. After it is set, it is all right now.

 set sync=true property in sync element. If its custom sink make sure it has sync implementation in it.

If your sync implimentaion lacks sync functionality then use element identity sync=true before the sink element.

But the play speed is very fast when I coded it in my GUI app with qml sink. The pipeline is the same except the sink is different.What can I do to set proper play rate?
