Including the module name-for which plugin or for which sample application, the function description) I’m using deepstream python test 3 to run inference on RTSP streams. I was looking for the functionality where I could reconnect to a stream when it gets disrupted, without restarting the pipeline. In the following link (Stream Disconnects In Deepstream Pipeline), it was suggested to use nvurisrcbin and set the “rtsp-reconnect-interval” property. So I replaced uridecodebin with nvurisrcbin in the python script and set the reconnect interval as 10. After that if I give 1 RTSP stream as input, disconnect its LAN cable and then reconnect it, the pipeline reconnects to the stream successfully after a certain time and resumes the processing of the stream as shown in following logs: Resetting source rtsp:stream1 **PERF: {'stream0': 0.0} Warning: gst-resource-error-quark: Could not read from resource. (9): gstrtspsrc.c(5769): gst_rtspsrc_reconnect (): /GstPipeline:pipeline0/GstBin:source-bin-00/GstDsNvUriSrcBin:uri-decode-bin/GstRTSPSrc:src: Could not receive any UDP packets for 5.0000 seconds, maybe your firewall is blocking it.

And when I reconnect the LAN cable for stream 1, the pipeline is not able to reconnect to either of the streams as shown in following logs: **PERF: {'stream0': 0.0, 'stream1': 0.2} Resetting source rtsp://stream1 Warning: gst-stream-error-quark: No data from source rtsp://stream1 since last 10 sec.

Any help regarding this would be greatly appreciated, thank you.

We’ll check this problem and notify you promptly once we have a conclusion.

We are still analyzing this issue. Because there are no issues with the C version(opt\nvidia\deepstream\deepstream\sources\apps\sample_apps\deepstream-test3\deepstream_test3_app.c) of the code, it may be a problem with Python binding or Python demo code logic.

Have you replicated this issue on your side? Also, do you have any suggestions regarding how I can handle this stream disconnection use case another way? I’m kind of stuck at the moment due to this.

[image] user87838: Have you replicated this issue on your side? Yes. It takes some time to analyze and solve. It can be updated in next version. Currently, you can consider using the C/C++ version. Or you can try using the nvmultiurisrcbin.

Thank you for your response. Unfortunately, C/C++ is not an option for me at the moment so I will try with nvmultiurisrcbin.

Tested the suggested change with 2 streams, reconnect functionality with nvurisrcbin is working fine now. Thank you. Having read the documentation for batched-push-timeout, I’m curious if this property’s value has to change depending on the number of streams. For example if I am processing 25 RTSP streams simultaneously, would I have to change its value accordingly?

[image] user87838: I’m curious if this property’s value has to change depending on the number of streams. No. You can set this value based on the duration of the frame interval or other appropriate value.

I tested on 6 public RTSP streams, for around 40-45 mins the streams were running fine. But then after that I could see that all streams had been disrupted, which I confirmed from the logs and display. The reconnecting functionality tried to reconnect for quite some time but except for stream3, it was not able to do so as shown in the logs. I checked the streams in both vlc media player and using a simple opencv script, they were running properly or at least had resumed running after the potential disruption. However, in the deepstream pipeline it did not resume the processing. Something interesting I noticed in the logs is that for stream3, it was not being reset and also its FPS was showing in the range 0.8-1.2. Stream3 was the only stream which was reconnected to successfully. Appreciate your help regarding this, thank you. six-streams-rtsp-reconnection.txt (48.1 KB) Note: I replaced the actual RTSP urls in the logs due to privacy.
