Hi .
I trying to build video and audio dender and receiver pipelines .

My sender pipeline is :

gst-launch gstrtpbin name=rtpbin videotestsrc ! ffmpegcolorspace ! ffenc_h263 ! rtph263ppay ! rtpbin.send_rtp_sink_0 rtpbin.send_rtp_src_0 ! udpsink host=127.0.0.1 port=5000 rtpbin.send_rtcp_src_0 ! udpsink host=127.0.0.1 port=5001 sync=false async=false udpsrc port=5005 ! rtpbin.recv_rtcp_sink_0 audiotestsrc ! audioconvert ! audioresample ! audio/x-raw-int, rate=11000, channels=1, endianness=1234, depth=16, signed=true ! faac ! rtpmp4gpay ! rtpbin.send_rtp_sink_1 rtpbin.send_rtp_src_1 ! udpsink host=127.0.0.1 port=5002 rtpbin.send_rtcp_src_1 ! udpsink host=127.0.0.1 port=5003 sync=false async=false udpsrc port=5007 ! rtpbin.recv_rtcp_sink_1

My receiver pipeline is :

gst-launch -v gstrtpbin name=rtpbin udpsrc caps="application/x-rtp,media=(string)video,clock-rate=(int)21000,encoding-name=(string)H263-1998" port=5000 ! rtpbin.recv_rtp_sink_0 rtpbin. ! rtph263pdepay ! ffdec_h263 ! sdlvideosink 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)11025, encoding-name=(string)MPEG4-GENERIC, encoding-params=(string)1, streamtype=(string)5, profile-level-id=(string)2, mode=(string)AAC-hbr, config=(string)1508, sizelength=(string)13, indexlength=(string)3, indexdeltalength=(string)3, ssrc=(uint)4286476404, payload=(int)96, clock-base=(uint)1631679159, seqnum-base=(uint)64394" port=5002 ! rtpbin.recv_rtp_sink_1 rtpbin. ! rtpmp4gdepay ! faad ! audio/x-raw-int, rate=11000, channels=1, endianness=1234, depth=16, signed=true ! sdlaudiosink udpsrc port=5003 ! rtpbin.recv_rtcp_sink_1 rtpbin.send_rtcp_src_1 ! udpsink port=5007 sync=false async=false

Once both are playing , The receiving side stops and exits the task , displaying in the console the following :

ERROR: from element /GstPipeline:pipeline0/GstUDPSrc:udpsrc0: Internal data flow
 error.

What is the reason ?
Are my caps in the receiver side not defined properly ?
What should be done to make this work ?


Thanks ,
Lior .
