I am using RTSP camera , the app is running fine but sometimes camera disconnected due to network issues. During this time app trying to reconnect the camera once the network is back. But it is not able to connect just show below error-

I am not able to find it’s root cause why it is not able to reconnect back only one solution is to restart the app and it works fine,

please help me to solve the issue and also provide the workaround so it can auto terminate when the reconnects attempts exceeds. SO our script can auto restart the app automatically.

I have attached the pipeline-

Something is wrong with the RTSP server, please check the RTSP server side.

Hi
I have checked the RTSP server , it is running fine .
The only issue is if camera disconnected from the app due to network then the app is not able to reconnect back the only solution is to restart the app.
if there is any rtsp server issue then it should not able to connect after the app restart also .

Please pay attention to the error, it is the RTSP server refused the connection. Please check with the RSTP server.

Ok , I will check.
Could you help me to stop the app when the reconnect attempts exceed so it can restart automatically.

You can stop the pipeline and restart the whole pipeline from beginning when you find out the RTSP server is ready.

Hi,

I can manually handle it, but I am using smart records where I have defined one parameter → rtsp-reconnect-attempts = 20. So, I want to know what happens when the reconnect attempts exceed 20. Does it shut down the app or pause it?

There is no update from you for a period, assuming this is not an issue anymore. Hence we are closing this topic. If need further support, please open a new one. Thanks

You need to call “NvDsSRStop()” and “NvDsSRDestroy()” explicitly to stop smart recording.
