Unable to add RTSP sink and Message broker together in deepstream pipeline

**• How to reproduce the issue ? **
Add RTSP sink and Kafka Message broker to the pipeline

        self.pipeline.add(self.msgconv)
        self.pipeline.add(self.msgbroker)

Adding these two lines to the code ends up in following warning:

sys:1: Warning: g_object_get_is_valid_property: object class 'GstUDPSrc' has no property named 'pt'

Pipeline works fine if either the RTSP sink or the Message brokers are removed.

Can you put your full pipeline graph?

@crv4415

_object_get_is_valid_property: object class 'GstUDPSrc' has no property named 'pt'

As far as I know, the above warning is not related to Message broker. It is a harmless message printed when you try to view the RTSP Stream.

rtsp_sources → nvstreammux → nvinfer → nvtracker → nvdsanalytics → nvmultistreamtiler → nvvideoconvert → nvdsosd → nvvideoconvert → tee

tee.0 → capsfilter → nvv4l2h264enc → rtph264pay → udpsink
tee.1 → nvmsgconv → nvmsgbroker

The pipeline works fine if I replace either of tee.0 or tee.1 with fakesink

The issue is now fixed, it occurred that I had added a fakesink to the pipeline which wasn’t actually linked anywhere in the pipeline. Removing the fakesink resolved the issue. :-)
