am using CONTROL STREAM for stop preview..

One solution is to use GMFBridge, which allows you to connect several graphs together and control them independently. That way you can have 3 graphs, one which connects your source to two sinks:
one for the preview:
and another for the capture:
Using GMFBridge you can then hook up the capture sink to the capture source and the preview sink to the preview source. Once that’s done you can start or stop the preview graph without affecting the capture graph, and vice versa. Hope that helps
