DeepStream dynamically delete source

rtspsrc,rtph264depay,nvv4l2decoder /----------------------------------------------\rtmpsinkbin

when I set rtspsrc element state:
GstStateChangeReturn state_return = gst_element_set_state (srcbin[i].rtspsrc, GST_STATE_NULL);

I got error from bus_call:

ERROR from element rtsp-src: Unhandled error
Error details: gstrtspsrc.c(6161): gst_rtspsrc_send (): /GstPipeline:pipeline/GstRTSPSrc:rtsp-src:
Option not supported (551)

But state_return is return as GST_STATE_CHANGE_SUCCESS

You may replace rtmpsinkbin with fakesink and try again. To make sure the issue is not triggered by rtmpsink.

And can try to launch RTP server through test-launch:

sudo apt-get install libgstrtspserver-1.0 libgstreamer1.0-dev
gcc test-launch.c -o test-launch $(pkg-config --cflags --libs gstreamer-1.0 gstreamer-rtsp-server-1.0)
[test-launch.c download from:]
./test-launch "filesrc location=sample_1080p_h264.mp4 ! qtdemux ! rtph264pay name=pay0 pt=96 "

To clarify if the issue is specific to the RTSP source.

replace rtmpsinkbin with fakesink: result is same error
use test-launch … : result is OK
but camera is hikvision ,everything is ok
How can I fix this bug ?

We have a sample for dynamically add/delete sources:

Please refer to it for your implementation.

I know this repo and test . will occur same error

It is solved by rtspssrc source code
