The sample deepstream_python_apps/apps/deepstream-test3 at master · NVIDIA-AI-IOT/deepstream_python_apps (github.com) is for multiple input streams, and it also supports single input stream.
- You don’t need to use two python apps to run multiple streams case and single stream case.
- I compared the python code in the two folders and notice that you set the nvstreammux “width” and “height” as 1280x720 in single stream app while 640x640 in multiple streams app. They should be set to both 1920x1080 for your test video resolution is 1920x1080.
