I tried your suggestion but still got error. When i try the first suggestion, I got the following error:<br>WARNING: erroneous pipeline: could not parse caps "video/x-h263,width=176,height=144,framerate=25\"<br>And then I removed the space after 25 (the frame rate - please look at the suggested caps below) and got the following error: WARNING: erroneous pipeline: could not link rtph263pdepay0 to avimux0. It considers as if the caps is not there.<br><br>When I use the second suggestion again with the space after 263, i got the same kind of error as above. When i delete the space, I got the following error:<br>streaming task paused, reason not-negotiated (-4)<br><br>I don't know what is hapening.<br><br>BTW, on the sender side I used the following command:<br>gst-launch v4l2src ! video/x-raw-rgb,width=320,height=240 ! queue ! videorate ! video/x-raw-rgb,rate=15/1 ! ffmpegcolorspace! ffenc_h263p ! rtph263ppay ! udpsink port=5000<br><br>I hope this will give you the clue about the problem. I run the command on Ubuntu Interpid.<br><br>Thank you.<br><br>- Zelalem S. <br><br>- Zelalem S. <br><br><hr id="stopSpelling">Date: Mon, 1 Jun 2009 13:52:34 +0530<br>From: bisht.sudarshan@gmail.com<br>To: gstreamer-devel@lists.sourceforge.net<br>Subject: Re: [gst-devel] How to save a stream from a network into a file<br><br><div>Hi ,</div> <div> </div> <div> for exapmle try these  :- </div> <div> </div> <div>         gst-launch-0.10 udpsrc port=5000 caps="application/x-rtp, media=(string)video,clock-rate=(int)90000, encoding-name=(string)H263-1998" num-buffers=5000 ! queue ! rtph263pdepay !  'video/x-h263,width=176,height=144,framerate=25 '   !    avimux ! filesink location=test.avi<br> <br>or </div> <div> </div> <div> gst-launch-0.10 udpsrc port=5000 caps="application/x-rtp, media=(string)video,clock-rate=(int)90000, encoding-name=(string)H263-1998" num-buffers=5000 ! queue ! rtph263pdepay !  'video/x-h263 '   !    avimux ! filesink location=test.avi<br> </div> <div> </div> <div> </div><br /><hr />See all the ways you can stay connected <a href='http://www.microsoft.com/windows/windowslive/default.aspx' target='_new'>to friends and family</a></body> </html>
