Hi, Dear developers
I'm writing a camera application using v4l2src as source plug-in, and I want to render the captured frame into clutter video sink.
At first, a view finding pipeline could be constructed and run successfully as expected, captured frames are displayed in the UI.
But issue occurs when I try to dynamically manipulate pipeline.
Say: click a button to set pipeline state to NULL, and then click button to set pipeline state to PLAYING, if I repeat for several times, my UI just hangs.

Has anyone encountered similar issue before, I think the category of this question is: UI hangs when dynamically manipulate pipeline.
Thanks a lot for your help!

Best Regards, Zheng, Huan(ZBT)
