Hi all.

I have problems sending a theora flow in streaming through rtp.

My two pipeline are the following:
Sender
1)gst-launch gstrtpbin name=rtpbin dv1394src ! dvdemux name=demux !
dvdec ! ffmpegcolorspace ! theoraenc ! rtptheorapay !
rtpbin.send_rtp_sink_0 rtpbin.send_rtp_src_0 ! udpsink port=5000
host=172.16.1.56  rtpbin.send_rtcp_src_0 ! udpsink port=5001
host=172.16.1.56 sync=false async=false udpsrc port=5005 !
rtpbin.recv_rtcp_sink_0

Receiver
2)gst-launch-0.10 gstrtpbin name=rtpbin udpsrc port=5000
caps="application/x-rtp,media=video,clock-rate=90000,encoding-name=THEORA,profile-level-id=1,payload=96"
                
! rtpbin.recv_rtp_sink_0 rtpbin. ! rtptheoradepay ! theoradec !
ffmpegcolorspace !
video/x-raw-rgb,bpp=32,endianness=4321,depth=24,red_mask=65280,green_mask=16711680,blue_mask=-16777216,width=720,height=576
                
! fakesink udpsrc port=5001 ! rtpbin.recv_rtcp_sink_0
rtpbin.send_rtcp_src_0 ! udpsink host=172.16.100.277 port=5005
sync=false async=false

The sender seems to works well but at the receiver i obtain the following error:
New clock: GstSystemClock
ERROR: from element /pipeline0/udpsrc0: Internal data flow error.
Additional debug info:
gstbasesrc.c(2240): gst_base_src_loop (): /pipeline0/udpsrc0:
streaming task paused, reason not-negotiated (-4)

Any suggestion? What could be the problem? A pipeline very similar
using MPEG4 works well.

Regards
Francesco Argese
