Error streaming RTSP with RTSP sink in deepstream-app

sorry, I mean, the command-line keeps on printing. please refer to the test in this topic.
please refer to create_udpsink_bin in\opt\nvidia\deepstream\deepstream-6.4\sources\apps\apps-common\src\deepstream_sink_bin.c, deepstraem-app uses updsink to send data to “224.224.255.255”. you can add a probe function on udpsink’ sink. if the function can always receive data, please check why tcpdump can’t receive data from 224.224.255.255. BTW, udpsink is Gsteamer Opensource plugin.
