Hi,

I am using iMX6Q nitrogen6X board.

I have been struggling with using mfw_v4lsrc sink for two video output for same screen. While it can be done using mfw_isink, but rtp streaming crashes  with in 10 mins with ioctl err.

 

gst-launch rtspsrc location= rtsp://10.10.4.11/vbStream1S1 typefind=true !  rtph264depay ! vpudec ! queue max-size-buffers=0 max-size-time=0 ! mfw_isink axis-top=0 axis-left=0 disp-width=960 disp-height=540
