Issues about using GStreamer to display multiple Camera RTSP Streaming

[Eric1994]

I'm using the i.MX 8M Mini with Linux Yocto Project BSP 5.10.72 2.2.1 Release;

I follow the <i.MX 8 GStreamer User Guide> document in the following link:

https://community.nxp.com/t5/i-MX-Processors-Knowledge-Base/i-MX-8-GStreamer-User-Guide/ta-p/1098942

And I use GStreamer to display 2 IP camera rtsp streams like this:

gst-launch-1.0 rtspsrc location=rtsp://admin:hk123456@192.168.8.64 latency=0 ! decodebin ! glimagesink render-rectangle='<0, 0, 600, 870>' &

gst-launch-1.0 rtspsrc location=rtsp://admin:hk123456@192.168.8.66 latency=0 ! decodebin ! glimagesink render-rectangle='<620, 0, 600, 870>' &

When these is only 1 rtsp stream, the video looks fine, when I add the second rtsp stream, the video start to blink, see the IMG_6040.mp4 video in the attachment.

How to deal with this blink issue?
