Hi, Nvida Team

Currently, I am testing the deepstream-app(python).My intention is 8 cameras real time streaming on 2x4 tile display and recording each of the cameras at the same time without AI Inference on jetson nano(later add AI inference) . Current python sample app"­deepstream-test3" that I am facing with some problem in “deepstream_test_3.py rtsp://10.1.1.11 rtsp://10.1.1.12” the problem is second rtsp is 15s delay from first rtsp. There is any possibility to solve that kind of issue. please be advice.

Software version : Jetpack 4.5.1 and Deepstream SDK 5.1

Best Regards

If you don’t want inference, you may try a pure gstreamer pipeline such as:

gst-launch-1.0 -ev \
nvcompositor name=mix  \
 sink_0::xpos=0 sink_0::ypos=0 sink_0::width=1280 sink_0::height=720 \
 sink_1::xpos=1280 sink_1::ypos=0 sink_1::width=1280 sink_1::height=720 \
 sink_2::xpos=0 sink_2::ypos=720 sink_2::width=1280 sink_2::height=720  \
 sink_3::xpos=1280 sink_3::ypos=720 sink_3::width=1280 sink_3::height=720 \
