Video Streaming over socket

[Yaroslav]

Thanks, Peter!
I just started to learn gstreamer. Now i try do my task using tcpserversink
and tcpclientsrc. But again faced with the problem.

if I use only 
/gst-launch-0.10 v4l2src device=/dev/video2 ! capsfilter
caps="video/x-raw-yuv,format=(fourcc)UYVY,width=720,height=625,framerate=(fraction)25/4"
! videocrop top=49 ! deinterlace mode=1 fields=1 ! videoscale ! capsfilter
caps="video/x-raw-yuv,width=360,height=270" ! ffmpegcolorspace ! avimux !
filesink location=/media/mmcblk1p1/$(date +"%Y.%m.%d_%H:%M:%S").avi/

all right!

if i try 

server
/gst-launch-0.10 v4l2src device=/dev/video2 ! tcpserversink port=3000/

client
/gst-launch-0.10 tcpclientsrc port=3000 ! capsfilter
caps="video/x-raw-yuv,format=(fourcc)UYVY,width=720,height=625,framerate=(fraction)25/4"
! videocrop top=49 ! deinterlace mode=1 fields=1 ! videoscale ! capsfilter
caps="video/x-raw-yuv,width=360,height=270" ! ffmpegcolorspace ! avimux !
filesink location=/media/mmcblk1p1/$(date +"%Y.%m.%d_%H:%M:%S").avi/

on client i see it

/Setting pipeline to PAUSED ...
Pipeline is PREROLLING ...

** (gst-launch-0.10:1645): WARNING **: videocrop0: size 49152 is not a

Please, help me to understand.
