i.MX6Q - GStreamer: How to clear the display after stopping the pipeline (using mfw_isink)

Hi All,

I'm playing and displaying multiple streams using mfw_isink. The system can dynamical switch from one Full screen stream to 4/12/16 streams. To achieve this I'm changing the state of each pipeline to NULL , changing the mfw_isink (x,y,h,w) then setting the state back to PLAY. This is working fine except that some pipelines occasionally leaves the last image on display. This means every time I NULL all the pipelines I will see this last image momentary until the state is set back to PLAY again.

It looks like I need to clear the mfw_isink  buffers before staring any new stream. What is the best way to do so?

 

Thanks
