help with live streaming

[Sebastián-2]

Hi! Im using gstreamer to capture video in my local machine. My pipeline is 

v4l2src device=/dev/video0 ! video/x-raw-yuv,width=320,height=240,framerate=10/1 ! ffmpegcolorspace ! capsfilter caps=video/x-raw-rgb,bpp=24 ! identity name=artoolkit ! fakesink

I would like to consume the live stream from other machine in my network. So i did the next:

Server:

v4l2src device=/dev/video0 ! video/x-raw-yuv,width=320,height=240,framerate=10/1 ! ffmpegcolorspace ! capsfilter caps=video/x-raw-rgb,bpp=24 ! identity name=artoolkit ! tcpserversink host=192.168.1.101 port=5000

Client:

tcpclientsrc host=192.168.1.101 port=5000  ! identity name=artoolkit ! ximagesink

when i try "gst-launch tcpclientsrc host=192.168.1.101 port=5000  ! identity name=artoolkit ! ximagesink" in the clien machine i get this error:

(gst-launch-0.10:8122): GLib-WARNING **: g_set_prgname() called multiple times

Estableciendo el flujo a PAUSADO ...

El flujo se está PRECACHEANDO ...

(gst-launch-0.10:8122): GStreamer-CRITICAL **: gst_caps_get_structure: assertion `GST_IS_CAPS (caps)' failed

ERROR: del elemento /GstPipeline:pipeline0/GstXImageSink:ximagesink0: Failed to create output image buffer of 0x0 pixels

Información adicional de depuración:

could not get shared memory of 0 bytes

ERROR: El flujo no quiere precachearse.

Estableciendo el conducto a NULL …

Liberando la tubería…

What im doing wrong?

Thanks you very much!!

if you don't have particular reasons for using tcp, I encourage you to
switch to udp (not that this is per se a reason for the failure). As
you're transferring over the network blocks bigger than the MTU, you
must either use a raw format (de)payloader as rtpvrawpay/rtpvrawdepay
or (better) compress and payload your stream with e.g. x264enc !
rtph264pay on the sending side, and do the opposite (rtph264depay !
ffdec_h264) on the other one. Of course, this works if in udp mode,
even better if you use gstrtpbin.

Regards
