gstrtpbin example code run not ok

Peter Xu
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?

Peter

Re: gstrtpbin example code run not ok

Kapil Agrawal
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 ?

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.

if it prints data logs at fakesink then you getting data, can you verify same ?
