The next problems.I use mfw_isink for draw pipeline to the screen.


1. Very offten  I have messages in console

createVideoSurface: max surfaces on device support on device1 exceeded!


After that, I can not draw any pipeline on screen. Only reboot can help me.


2. Very offten mfw_isink plugin freeze. I.e. program freeze in


const char * p3="appsrc name=mysource is-live=true !  video/x-h264 ! h264parse  ! vpudec framedrop=true low-latency=true !  mfw_isink name=vsink  sync=true  max-lateness=5000000000 qos=true";

GstElement * pipeline=gst_parse_launch(p3,NULL);


In this case, 

gst-inspect mfw_isink

also freeze


I think, problem in VPU driver from imx, or in mfw_isink plugin



How to reload/reset this driver without rebooting?
