Hi,  
We suggest use _nvv4l2decoder_ since omx plugins are deprecated. Please try this sample and check if video preview is good:  
[Doesn't work nvv4l2decoder for decoding RTSP in gstreamer + opencv - #3 by DaneLLL](https://forums.developer.nvidia.com/t/doesnt-work-nvv4l2decoder-for-decoding-rtsp-in-gstreamer-opencv/140321/3)

And then it should work by applying the URI to this sample:
