I followed Wim's very helpful advice. It goes a bit further than before.

Hi Wim,
Thanks for the quick reply. I fixed the width and height to be the same. Now it just sits there after going to playing state. Cpu utilization is about 10 percent. I expected it to open a window for ximagesink, but it does not. I see some strange caps: /GstPipeline:pipeline0/GstRtpVRawDepay:rtpvrawdepay0.GstPad:src: caps = video/x-raw-rgb, width=(int)400, height=(int)300, format=(fourcc)0x00000000, framerate=(fraction)0/1 The framerate is 0, despite the fact that I set it to 10. Thanks again, Bert Douglas On Fri, Sep 3, 2010 at 11:47 AM, Wim Taymans <[hidden email]> wrote:

In reply to this post by Bert Douglas
Hi!
I'm having the same problem as Bert when using rtpvrawdepay. When I try to stream raw rgb video data, the pipeline runs, but does not display anything. >From the debug information it seems that the srcpad of the depayloader cannot link to the sinkpad of ffmpegcolorspace. If I use video/x-raw-yuv there is no such problem. Below are the two actual pipelines I use. However, the problem also occurs when I start something like this: gst-launch --verbose videotestsrc ! video/x-raw-rgb ! rtpvrawpay ! rtpvrawdepay ! ffmpegcolorspace ! dshowvideosink Again, if I replace "rgb" by "yuv" the pipeline works fine. Sender pipeline: gst-launch --verbose gstrtpbin name=r videotestsrc ! video/x-raw-rgb, width=320, height=120, bpp=32, depth=32, framerate=1/1 ! rtpvrawpay ! r.send_rtp_sink_0 r.send_rtp_src_0 ! udpsink host=... port=5000 r.send_rtcp_src_0 ! udpsink port=5001 sync=false async=false udpsrc port=5002 ! r.recv_rtcp_sink_0 Receiver pipeline: gst-launch gstrtpbin name=rtpbin udpsrc caps="application/x-rtp, media=(string)video, clock-rate=(int)90000, encoding-name=(string)RAW, sampling=(string)RGBA, depth=(string)8, width=(string)320, height=(string)120, colorimetry=(string)SMPTE240M" port=5000 ! rtpbin.recv_rtp_sink_0 rtpbin. ! rtpvrawdepay ! video/x-raw-rgb,width=320,height=120,bpp=32,depth=32,framerate=1/1, red_mask=0xff000000,green_mask=0x00ff0000,blue_mask=0x0000ff00,alpha_mask=0x000000ff ! ffmpegcolorspace ! dshowvideosink udpsrc port=5001 ! rtpbin.recv_rtcp_sink_0 rtpbin.send_rtcp_src_0 ! udpsink port=5002 sync=false async=false I am currently using the latest OSSBuild (0.10.7 beta4) but I have also tried (0.10.6).

Dear Wim,
Thanks for the quick reply. What I do not understand: why does it say video/x-raw-rgb in the caps (see result of gst-inspect below)? Does the code in gstrtpvrawdepay.c referring to "video/x-raw-rgb" or "RGBA" have no effect?
