I'm trying to create gstreamer pipeline with rtpbin to stream webcam both way (videophone). However, I am not even able to make rtpbin work with simple snippet like below which just takes webcam source and streams out, then other udpsrc captures RTP packets and displays. All localhost. When splitted to two pipes and launched separately, it works. This, however, not. I feel it has something with threading, however I am stucked here as no queue worked for me so far. Basically, what I need is displaying incomming videostream and stream out my webcam videostream out to remote party.
gst-launch -v \ gstrtpbin name=rtpbin \ udpsrc caps="application/x-rtp,media=(string)video,clock-rate=(int)90000,encoding-name=(string)H263" port=5000 ! rtpbin. \ rtpbin. ! rtph263depay ! ffdec_h263 ! ffmpegcolorspace ! xvimagesink \ v4l2src ! video/x-raw-yuv, framerate=30/1, width=320, height=240 ! videoscale ! videorate ! "video/x-raw-yuv,width=352,height=288,framerate=30/1" ! ffenc_h263 ! rtph263pay ! rtpbin. \ rtpbin. ! udpsink port=5000
