Problem with multiple RTSP streams. Pipeline Freezes

[juan.isern95]

Hello everyone,

Please provide complete information as applicable to your setup:

• Hardware Platform (Jetson / GPU): 2xA30
• DeepStream Version: 6.2
• TensorRT Version: 8.5.2-1+cuda11.8
• NVIDIA GPU Driver Version (valid for GPU only): 530.30.02
• Issue Type( questions, new requirements, bugs): Question

I have a deepstream python application that takes multiple input video streams (up to 64) from dynamically created RTSP sources (Using the runtime_source_add_delete.py example).

However, sometimes an error pops up unexpectedly interrupting the pipeline. I say interrupting because the pipeline freezes, unable to get data from the incoming videos. I have seen this error occur randomly, but very frequently.

**(python3:1): GStreamer-CRITICAL : 06:28:50.353: gst_value_init_and_copy: assertion ‘G_IS_VALUE (src)’ failed

**(python3:1): GStreamer-CRITICAL : 06:28:50.358: gst_value_init_and_copy: assertion ‘G_IS_VALUE (src)’ failed

**(python3:1): GStreamer-CRITICAL : 06:28:50.380: gst_value_init_and_copy: assertion ‘G_IS_VALUE (src)’ failed

Attached is a log of my execution with GST=4.

Please, I need recommendation on what to do,

Hello again,

I have tried another system and it works correctly. This new system is:

• Hardware Platform (Jetson / GPU): RTX2080TI
• DeepStream Version: 6.2
• TensorRT Version: 8.5.2-1+cuda11.8
• NVIDIA GPU Driver Version (valid for GPU only): 530.30.02
• Issue Type( questions, new requirements, bugs): Question

For both tests I use the DS6.2-Devel container.

Kind regards

EDIT: It doesn’t really work, on either system. I have tried repeatedly and at a certain point, it stops working and the pipeline freezes.

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

There seems to be an error in the rtsp source in the log.

Do you modify the file of deepstream_rt_src_add_del.py ? If yes,can you share the patch and configure file ?

In the function of def bus_call(bus, message, loop), do you see some error log ?
if rtsp source have problem,you can reconnect when meet error.
