Hello.
I was digging this forum and can not get info about using gstreamer.
As fast as I get stream in opencv but it has low fps.
Can anybody give me advise max resolution, max stream parameters etc. How implement gpu decoding in gstreamer, If it possible please send gstreamer in opencv.
When I’m using videobin I have huge fps but with high latency.
I’m dealing with it for so long.

You can modify the pipeline to run
urdecodebin uri=rtsp://RTSP_SOURCE_URI ! nvvidconv ! video/x-raw(memory:NVMM),format=RGBA ! nvoverlaysink
