Trying to create a file compatible with [[freeplayer]] like this one  :

    w=480; h=360 
    w=800; h=600


    out=/tmp/tmp.mpg
    num_buffers=64

    gst-launch \
	videotestsrc num_buffers=${num_buffers} \
	! videoscale ! video/x-raw-yuv, width=$w,height=$h,framerate=\(fraction\)25/1 \
	! ffmpegcolorspace \

Then using vlc as a gateway, seems to work, but far than a real stream

Now must set ts-pid, rtp etc but how ?

<code>
 gst-launch videotestsrc num_buffers=${num_buffers} ! videoscale ! video/x-raw-yuv, width=$w,height=$h,framerate=\(fraction\)25/1 ! ffmpegcolorspace ! ffenc_mpeg1video  !  udpsink port=1234 host=212.27.38.253
