gst-launch -v gstrtpbin name=rtpbin v4l2src device=/dev/video0 queue-size=16 ! video/x-raw-yuv,width=352,height=288 ! queue ! rtpvrawpay ! rtpbin.send_rtp_sink _0 rtpbin.send_rtp_src_0 ! queue ! udpsink host=10.130.11.4 port=5000 ts-offset= 0 rtpbin.send_rtcp_src_0 ! udpsink host=10.130.11.4 port=5001 sync=false async=f alse udpsrc port=5005 ! rtpbin.recv_rtcp_sink_0 but it show ERROR: Pipeline doesn't want to pause.
