Hi Damiano,<div> </div><div>I am doing a similar thing on the dm368. I am currently planning on using the queue element. If you read the documentation on the queue element (<a href="http://gstreamer.freedesktop.org/data/doc/gstreamer/head/gstreamer-plugins/html/gstreamer-plugins-queue.html">http://gstreamer.freedesktop.org/data/doc/gstreamer/head/gstreamer-plugins/html/gstreamer-plugins-queue.html</a>) you'll see that it has some minimum value properties (buffers/bytes/time). I was planning on setting a minimum value to store enough buffered video inside of the queue and installing a buffer probe on the source pad of the queue to throw out buffers when I don't want to store them.</div> <div> </div><div>If anyone else has a better way of doing this in gstreamer, let me know.</div><div> </div><div>-Randy</div><div class="gmail_extra"> <div class="gmail_quote">On Fri, Nov 9, 2012 at 5:39 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, I read in a forum that queue can work with live-sources, while queue2 can't (right now). But I consider this information old, beacuse the message is dated to 09/2010. Do you have some newest information about it? To better explain my need, I'm working on a IP camera base on dm365 that used gstreamer. The pourpose is this: when an interrupt arrives (for example due to motion detection) I must have a 30 seconds video before it to undestand what have generated the interrupt. I think to do this with a sort of circular buffer before sink element. This new element will continue to store data, and when an interrupt arrives it must reorder the buffer and put the content into a file. After that start to normally send video to sink element.
