I refer to test1-cam and test3 in the example of deepstream python version on github I want to run multiple USB cameras on deep stream

this is my code

code.py (13.9 KB)
This is the return message that gets stuck after running：
CMD.txt (2.8 KB)

Looking forward to your reply.
thx

Besides tao models, did you ever try other models? Can it run successfully?

4

It doesn’t work. Could it be that I have a problem connecting to the <Gst.ElementFactory.make> element, or can you send me a sample code for using multiple usb cameras for my reference?

5

Which model did you try?

6

RESNET53

7

Is it a tao model? I just want to know if this issue happens in other kind of models instead of tao models.

Running this project alone (GitHub - gggcy/AIC2020_ReID: Implementation of Vehicle Re-Identification Based on Complementary Features for 2020 AICity Challenge Track2) it works

Please try to check if you can use multiple camera to run a demo model in deepstream. For example,
/opt/nvidia/deepstream/deepstream-6.0/samples/models/Primary_Detector/resnet10.caffemodel

demo model can work

Hello, I’m so sorry bother you. Can you send me a sample code for using multiple USB cameras for my reference？

For the sample code running with multiple USB camera, can you search in Deepstream forum or create a new topic in deepstream forum? I am focusing on TAO forum.

Okay, thanks for help
