Hi. Can you write the transmission pipeline? Which board are you using? Lorenzo <div class="gmail_quote">2010/4/11 Mailing List SVR <<a href="mailto:lists@svrinformatica.it">lists@svrinformatica.it</a>> <blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">I added a videorate element so this pipeline works: <div class="im"> gst-launch-0.10 -e -v udpsrc port=6000 caps="application/x-rtp, media=(string)video, clock-rate=(int)90000, encoding-name=(string)JPEG, </div>payload=(int)26" ! .recv_rtp_sink_0 gstrtpbin ! rtpjpegdepay ! videorate ! image/jpeg, width=352, height=288, framerate=3/1 ! avimux ! filesink location=test-gst.avi but if I don't know the framerate or the framerate is variable how can I tell to gstreamer to autodetect these infos?
