Hi,
We have a sample config file for running deepstream-app:
deepstream-5.0\samples\configs\deepstream-app\source1_usb_dec_infer_resnet_int8.txt
You may give it a try.
Fo rrunnign through gst-launch-1.0, please refer to
And configure exact mode(width,height,format,framerate).
And try to execute sudo jetson_clocks and set nveglglessink sync=false
