while running multi_stream_detection.sh I am encountering an error : “Setting number of rtsp sources to 1

Running Pipeline…
./multi_stream_detection_rtsp.sh: eval: line 135: syntax error near unexpected token `<’
"
while I have re verified the .sh file but not such token present in the code and I am using the rtsp link in format (RC_0=“rtsp://192.168.0.110/?h264x=4<admin_123>” )
I believe the issue is your rtsp source string.
Try this:
RC_0="rtsp://192.168.0.110/?h264x=4 user-id=admin_123 user-pw=pw_123"
I changed the rtsp link format but getting error:

Hi @prateek.s
Please verify that you are able to read from the camera using just a simple pipeline reading from RTSP and displaying to screen.
There are plenty of examples online.
Note that the RTSP address is different between different cameras brands.
You can also use VLC to ensure that the RTSP URL rtsp://192.168.0.110/?h264x=4 is working and streaming video correctly.
After you approve that this works we can delve deeper.
now I have verified the rtsp link by running it on VLC player its running fine but while running the shell code for rtsp detection the error arose again.

Please try to run a gstreamer pipeline (w/o hailo) to make sure this is not an issue with the camera configuration (VLC has better support than gstreamer).
In addition please share your system details.

camera is working fine on VLC but facing error while running the sh file
i have tried changing the streames of camera from main stream to sub stream but same error
Try use rtsp strem for this camera in format:
Main stream rtsp://Camera IP address:554/media/video1
Sub stream rtsp://camera IP address:554/media/video2
Third stream rtsp://camera IP address:554/media/video3
I suggest using the second stream
If the RTSP authentication is enabled on camera then please use the following URL:
rtsp://username:password@IP:RTSP port/media/videoX
Thanks for the reply but I am already using the IP in this format “rtsp://admin:admin_123@192.168.0.114:554/media/video1”
i think the error “failed delayed linking some pad of GstRTSPSrc named source_0 to some pad of GstRtpH264Depay named rtph264depay0”
is regarding the encoding/decoding segment of the stream connectivity.
may be you can provide some input in that error.
