Huge dynamic pipeline manipulation

sielf
Hello.
I'm working with IMX6 based board with gstreamer-1.4.5 framework version.
I've constructed next (simpified) pipeline : src--queue--tee--queue--videosink
                                                                                  |--queue----coder---muxer--filesink
Now I want to stop saving video to the file without changing videosink branch. I've tried probes to do this. I've added probe where I unlinked second branch and remove from pipeline. But when I use hardware based operation and queues, pipeline stucks.What would be better solution to do described operation?
