[gst-devel] GStreamer RTSP Server Multicast RTP Question

[Robert Krakora]

Hello,

I can successfully capture and send unicast video and audio data from a v4l2
webcam and microphone via gst-rtsp RTSP server when requested by an RTSP
client.  However, I cannot seem to figure out how to send multicast video
and audio data.  I am using the test-launch example provided with gst-rtsp
in both cases.  However, case (2) below yeilds nothing when an RTSP client
request arrives.  What am I doing wrong?  Thanks in advance.  ;-)

Case 1 (Unicast)

/home/silentm/MessageNet/totem/gst-rtsp-0.10.5/examples/test-launch
--gst-debug=255 "( v4l2src device=/dev/video0 ! ffmpegcolorspace !
video/x-raw-yuv,width=640,height=480,framerate=30/1 ! theoraenc quality=10
bitrate=6000 speed-level=2 ! rtptheorapay pt=96 name=pay0 alsasrc
device="hw:0,0" ! audioconvert ! vorbisenc ! rtpvorbispay pt=97 name=pay1 )"

Case 2 (Multicast?)

/home/silentm/MessageNet/totem/gst-rtsp-0.10.5/examples/test-launch
--gst-debug=255 "( gstrtpbin name=rtpbin v4l2src ! ffmpegcolorspace !
theoraenc ! rtptheorapay ! rtpbin.send_rtp_sink_0 rtpbin.send_rtp_src_0 !
udpsink port=5000 host=224.2.8.13 rtpbin.send_rtcp_src_0 ! udpsink port=5001
host=224.2.8.13 sync=false async=false udpsrc port=5005 !
rtpbin.recv_rtcp_sink_0 alsasrc device="hw:0,0" ! audioconvert ! vorbisenc !
rtpvorbispay ! rtpbin.send_rtp_sink_1 rtpbin.send_rtp_src_1 ! udpsink
port=5002 host=224.2.8.13 rtpbin.send_rtcp_src_1 ! udpsink port=5003
host=224.2.8.13 sync=false async=false  )"

Best Regards,
