Hi Marco<div><br></div><div>thank you so much for the help, it worked very well here... But what I want is to store the video at the receiver in the disk. I tried to modify this example that you sent to me, but it didn't saved the video. I modified the following in the recv.c. I used the foreman_cif.yuv video sample (352x288).</div> <div><br></div><div><br></div><div><div>#define PIPELINE_FORMAT "\</div><div>gstrtpbin name=rtpbin \</div><div>udpsrc caps=\"application/x-rtp,media=(string)video,clock-rate=90000,encoding-name=(string)H264\" \</div> <div>port=5000 ! rtpbin.recv_rtp_sink_0 \</div><div>rtpbin. ! rtph264depay ! ffdec_h264 ! <b>\" video/x-raw-yuv, width=352, height=288, format=(fourcc)I420 \" ! filesink location=test_rcv.yuv</b> ! \</div><div> udpsrc port=5001 ! rtpbin.recv_rtcp_sink_0 \</div> <div>rtpbin.send_rtcp_src_0 ! udpsink port=5005 sync=false async=false"</div></div><div><br></div><div><br></div><div>it returned an error: </div><div><div><br></div><div>Error: internal error in data stream.</div></div> <div><br></div><div>I'm very gratefull for your help.</div><div><br></div><div>regards</div><div><br></div><div><br><br><div class="gmail_quote">On Sun, Oct 31, 2010 at 4:48 PM, Marco Ballesio <span dir="ltr"><<a href="mailto:gibrovacco@gmail.com">gibrovacco@gmail.com</a>></span> wrote:<br> <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex;">mmhh.. md5 from: <a href="http://gstreamer-devel.966125.n4.nabble.com/how-to-learn-from-yuv-files-and-encode-with-h-264-td3017365.html#a3017365" target="_blank">http://gstreamer-devel.966125.n4.nabble.com/how-to-learn-from-yuv-files-and-encode-with-h-264-td3017365.html#a3017365</a><br> <br>is different.

The second app opens a connection and renders all the h264 frames it receives from it.
