Gstreamer - Hello world, to make a video test. Its simple and but not working.

[Shamun Shamun]

This is my simple video test, for sending a raw video in the port 2222, and
receive it via port 2222 for display. But it does not work, any help for
this please?

Example:

    sender: $gst-launch -v videotestsrc ! udpsink host=127.0.0.1
auto-multicast=true port=2222
    Setting pipeline to PAUSED ...
    /GstPipeline:pipeline0/GstVideoTestSrc:videotestsrc0.GstPad:src: caps =
video/x-raw-yuv, format=(fourcc)YUY2, color-matrix=(string)sdtv,
chroma-site=(string)mpeg2, width=(int)320, height=(int)240,
framerate=(fraction)30/1
    Pipeline is PREROLLING ...
    /GstPipeline:pipeline0/GstUDPSink:udpsink0.GstPad:sink: caps =
video/x-raw-yuv, format=(fourcc)YUY2, color-matrix=(string)sdtv,
chroma-site=(string)mpeg2, width=(int)320, height=(int)240,
framerate=(fraction)30/1
    Pipeline is PREROLLED ...
    Setting pipeline to PLAYING ...
    New clock: GstSystemClock

    receiver: $ gst-launch -v udpsrc multicast-group=127.0.0.1 port=2222 !
video/x-raw-yuv,width=320, height=240 ! ffmpegcolorspace ! ximagesink
