Issue when using two IP cameras with OpenVINO OMZ Demo

Hello,

 

My customer is trying out this demo by using 2 IP cameras.

https://docs.openvinotoolkit.org/2021.3/omz_demos_multi_channel_face_detection_demo_cpp.html

 

When they are using 1 IP Camera it worked perfectly but when 2 IP cameras it came out with errors as attached.

Command line as below:

-i rtsp://admin:gamma@172.18.70.113:8554/CH001.sdp/ rtsp://admin:admin@172.18.70.125:8554/CH001.sdp/

Any idea?

 

Thanks,.

I see error message on your screenshot: 404 stream not found. Is there streaming going on this rtsp connections?

Hello @Vladimir_Dudnik 

 

Yes the streaming is ongoing with RSTP connections.

 

We did tried a few scenario:

1) Command: multi_channel_face_detection_demo.exe -i rtsp://admin:gamma@172.18.70.113:8554/CH001.sdp/ rtsp://admin:admin@172.18.70.125:8554/CH001.sdp/ -m face-detection-retail-0004.xml 

Result: Only show Inference on rtsp://admin:gamma@172.18.70.113:8554/CH001.sdp/

2) Command (Adding comma in between the rstp input): 

multi_channel_face_detection_demo.exe -i rtsp://admin:gamma@172.18.70.113:8554/CH001.sdp/, rtsp://admin:admin@172.18.70.125:8554/CH001.sdp/ -m face-detection-retail-0004.xml 

Result: Only show Inference on rtsp://admin:gamma@172.18.70.113:8554/CH001.sdp/


Seems like the OMZ Demo is unable to run Inference on the 2nd RSTP input.

Any idea?

Hi DarkHorse,

Thank you for reaching out to us.

 

I encountered the same error method DESCRIBE failed: 404 Not Found as your customer did when I run Multi-Channel Face Detection C++ Demo with your command:

multi_channel_face_detection_demo.exe -m "<path_to_xml_file>\face-detection-adas-0001.xml" -i rtsp://camera_address_1/ rtsp://camera_address_2/

 

On another note, I successfully run the Multi-Channel Face Detection C++ Demo by using a comma instead of a space to seperate two IP camera address. The command is:

multi_channel_face_detection_demo.exe -m "<path_to_xml_file>\face-detection-adas-0001.xml" -i rtsp://camera_address_1,rtsp://camera_address_2

 

 

Regards,

Wan

Hello @Wan_Intel ,

 

Thanks, we managed to get it run also on the following command:

multi_channel_face_detection_demo.exe -m "<path_to_xml_file>\face-detection-adas-0001.xml" -i "rtsp://camera_address_1,rtsp://camera_address_2"

I guess the openvino documentation need to be updated..

Thanks.
