Hi,
I am trying to stream a video in network and using the below command to
stream:
gst-launch -v filesrc location=1.avi ! decodebin2 ! ffmpegcolorspace !
video/x-raw-yuv ! videorate ! video/x-raw-yuv,framerate=10/1 !  videoscale !
video/x-raw-yuv,width=640,height=480 ! clockoverlay ! rtpvrawpay ! udpsink
host=localhost port=5000 sync=false

output of above command is:
:
:
/GstPipeline:pipeline0/GstUDPSink:udpsink0.GstPad:sink: caps =
application/x-rtp
, media=(string)video, clock-rate=(int)90000, encoding-name=(string)RAW,
samplin
g=(string)YCbCr-4:2:0, depth=(string)8, width=(string)640,
height=(string)480, c
olorimetry=(string)SMPTE240M, payload=(int)96, ssrc=(guint)3854949446,
clock-bas
e=(guint)906919570, seqnum-base=(guint)61841
Pipeline is PREROLLED ...
Setting pipeline to PLAYING ...
New clock: GstSystemClock

And at receiver end I am running the following command to get the
video(using the caps in above command output):
gst-launch -v udpsrc port=5000 caps ="application/x-rtp,
media=(string)video, clock-rate=(int)90000, encoding-name=(string)RAW,
sampling=(string)YCbCr-4:2:2, depth=(string)8, width=(string)640,
height=(string)480, colorimetry=(string)SMPTE240M, payload=(int)96,
ssrc=(guint)3143582158, clock-base=(guint)2032309802,
seqnum-base=(guint)43299" ! rtpvrawdepay ! autovideosink

At receiver end I am not getting the proper video, although the video screen
is displayed but the video is not clearly visible and video is also moving
very fast(as if running in fast forward mode).
Can anyone help why the video is not clear and moving very fast
Thanks in advance.
