Hi,

$ gst-launch-1.0 uridecodebin uri=rtsp://admin:vnnet123456@192.168.1.202 ! nvoverlaysink

Please use DS4.0.1 and check if the uri is valid or not.

Hi. Thank you.
I have connected many ip cameras.
Is there any way to increase performance? ( examole Yolo v3)
Present:
1 camera detection: FPS: 24
2 camera detection: FPS: 12
4 camera detection: FPS: 6

Hi,
Do you run deepstream_app_config_yoloV3.txt or deepstream_app_config_yoloV3_tiny.txt?

I run deepstream_app_config_yoloV3_tiny.txt

Hi,

Please check this comment:
https://devtalk.nvidia.com/default/topic/1064871/deepstream-sdk/deepstream-gst-nvstreammux-change-width-and-height-doesn-t-affect-fps/post/5392823/#5392823

This sample can reach 20 FPS with YOLOv3 on Nano.

Thanks.

My project also gets 20 fps on yolov3-tiny.
but when using multiple cameras, it is reduced.
Is there a workaround?

Hi,

YoloV3 is much complicated than the tiny version.
Try to apply the similar update to the YOLO_tiny and you should get a better result than 20FPS.

Thanks.

I also used yolov2_tiny, the results were improved with 25 fps.
but when using multiple cameras, the result is reduced.

result: 1 cam

result: 4 cam

Hi,

Could you share your config for multi camera with us?

Have you updated the batch size of streammux and primary-gie into 4?
For 4 stream input, the streammux and nvinfer batch size need to be 4 as well.

Thanks.

Hi,
Could you share your config file for multiple cameras ?
I am trying to run yolo3 on multiple cameras, but still no idea how to modify config file

thanks!

Hi,
You have shared the result of running 4 cam. Would be better if you can share the config file of running 4 cam.
