hi, all,
I am trying to encode some raw data with h264, and sent via network in rtp. I found some example pipelines here: http://gstreamer.freedesktop.org/data/doc/gstreamer/head/gst-plugins-good-plugins/html/gst-plugins-good-plugins-gstrtpbin.html I used this code to establish a server(nearly the same as mentioned in the doc above, just change v4l2src to videotestsrc): gst-launch gstrtpbin name=rtpbin \ videotestsrc ! ffmpegcolorspace ! ffenc_h263 ! rtph263ppay ! rtpbin.send_rtp_sink_0 \ rtpbin.send_rtp_src_0 ! udpsink port=5000 \ rtpbin.send_rtcp_src_0 ! udpsink port=5001 sync=false async=false \ udpsrc port=5005 ! rtpbin.recv_rtcp_sink_0 \ audiotestsrc ! amrnbenc ! rtpamrpay ! rtpbin.send_rtp_sink_1 \ rtpbin.send_rtp_src_1 ! udpsink port=5002 \ rtpbin.send_rtcp_src_1 ! udpsink port=5003 sync=false async=false \ udpsrc port=5007 ! rtpbin.recv_rtcp_sink_1 and use this to run the client: gst-launch -v gstrtpbin name=rtpbin \ udpsrc caps="application/x-rtp,media=(string)video,clock-rate=(int)90000,encoding-name=(string)H263-1998" \ port=5000 ! rtpbin.recv_rtp_sink_0 \ rtpbin. ! rtph263pdepay ! ffdec_h263 ! ximagesink \ udpsrc port=5001 ! rtpbin.recv_rtcp_sink_0 \ rtpbin.send_rtcp_src_0 ! udpsink port=5005 sync=false async=false \ udpsrc caps="application/x-rtp,media=(string)audio,clock-rate=(int)8000,encoding-name=(string)AMR,encoding-params=(string)1,octet-align=(string)1" \ port=5002 ! rtpbin.recv_rtp_sink_1 \ rtpbin. ! rtpamrdepay ! amrnbdec ! alsasink \ udpsrc port=5003 ! rtpbin.recv_rtcp_sink_1 \ rtpbin.send_rtcp_src_1 ! udpsink port=5007 sync=false async=false however, by first running the server, then running the client, I can't see a xwindow pop up (I think I should see that, meanwhile some kind of sine wave should be played in my audio) nor the sine wave sound. what I got after running the client are: .... New clock: GstSystemClock /GstPipeline:pipeline0/GstRtpBin:rtpbin.GstGhostPad:send_rtcp_src_1: caps = application/x-rtcp /GstPipeline:pipeline0/GstRtpBin:rtpbin/GstRtpSession:rtpsession1.GstPad:send_rtcp_src: caps = application/x-rtcp /GstPipeline:pipeline0/GstUDPSink:udpsink1.GstPad:sink: caps = application/x-rtcp /GstPipeline:pipeline0/GstRtpBin:rtpbin.GstGhostPad:send_rtcp_src_1.GstProxyPad:proxypad5: caps = application/x-rtcp /GstPipeline:pipeline0/GstRtpBin:rtpbin.GstGhostPad:send_rtcp_src_0: caps = application/x-rtcp /GstPipeline:pipeline0/GstRtpBin:rtpbin/GstRtpSession:rtpsession0.GstPad:send_rtcp_src: caps = application/x-rtcp /GstPipeline:pipeline0/GstUDPSink:udpsink0.GstPad:sink: caps = application/x-rtcp /GstPipeline:pipeline0/GstRtpBin:rtpbin.GstGhostPad:send_rtcp_src_0.GstProxyPad:proxypad2: caps = application/x-rtcp Does anyone know what's the problem here?

I would first test if at all my server is sending data.
For that just run gst-launch udpsrc caps="application/x-rtp,media=(string)video,clock-rate=(int)90000,encoding-name=(string)H263-1998" port=5000 ! fakesink -v if it prints data logs at fakesink then you getting data, can you verify same ?

2011/6/13 Kapil Agrawal <[hidden email]> I would first test if at all my server is sending data. Thanks for your suggestion. It seems that there is no udp packat recved. And I think I have found the problem here, which is very strange. In the server script, I have to add "host=127.0.0.1" to udpsink, then I will see something with the fakesink -v.
What is strange is that, the default "host" param of udpsink is "localhost", which should be the same as 127.0.0.1. However, only "127.0.0.1" works, and "localhost" won't.
By the way, I have found a workable script showing how to do x264 enc/dec via internet. they are:
Here also a audio examples with a-law encoding, which is really what I needed.
