Try setting the intra-refresh rate on the server to a higher frequency (more intra-refresh frames transmitted). Then you should probably capture N seconds after receiving an intra-refresh frame rather then simply N seconds from some arbitrary start time. <div class="gmail_quote">On Tue, Dec 18, 2012 at 4:22 AM, Damiano Pinarello <<a href="mailto:damiano.pinarello@bticino.it" target="_blank">damiano.pinarello@bticino.it</a>> wrote: <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"> Hi all, I use this pipeline on dm365 to capture h264 video from rtsp-server: gst-launch \ rtspsrc latency=50 rtsp://<a href="http://127.0.0.1:3070/delayed.264" target="_blank">127.0.0.1:3070/delayed.264</a> ! \ rtph264depay \ rtph264pay \ valve drop=TRUE \ filesink location=/var/tmp/record.264 When I send ad interrupt valve drop parameter change rom TRUE to FALSE, and after Xsecs, re-change from FLASE to TRUE. So I obtain a h264 video of Xsecs. The problem is that I can't play the video. For me, probably, this is due to the missing of heander h264 beacuse I didn't captured video from the beginning of the stream. Mainly, I capture video from time X to time Y. Any suggestions about this isseu?
