Hello Everyone,
I got some problems with run python test apps (Deepstream-test1 and Deepstream-test3 ) for stream my RTSP camera.

1) With Deepstream_Test3 case

nhan@nhan-desktop:/opt/nvidia/deepstream/deepstream-5.0/sources/deepstream_python_apps/apps/deepstream-test3$ python3 rtsp://admin:TX****@

if not Gst.Bin.add(self, arg):

2) With Deepstream-test1 case

Could someone give me some advices for 2 case. How i can stream my camera? And in the future, i want stream 4 cameras in the same time with jetson nano, so Need i choose Deepstream Test3 or Test1 ?

  1. Please read the README file for, it only support H264 ES local stream. It is wrong to run it with rtsp input.
  2. Can you run the following command on your platform to check whether there are nvstreammux, nvinfer , nvvideoconvert,… in your platform? Seems your DeepStreamSDK is not installed correctly.

Thanks for your advices, i will check again
