Yes, I did exactly what is written in the header of shmpipe.h. I don't understand why it doesn't work as it should. Well, if I don't find any solution to this problem, I'll just make the client connect as soon as the stream starts, but it's not the best way.. <div class="gmail_quote">2012/7/24 Olivier Crête <<a href="mailto:olivier.crete@collabora.com" target="_blank">olivier.crete@collabora.com</a>> <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"> <div class="im">On Tue, 2012-07-24 at 05:55 -0700, Takido wrote: > I managed to extract a stream from Gstreamer using shmsink, and it works > correctly when the property "wait-for-connection" is set to false. > I'd like the property to be set to true so that the stream starts only when > I want it to start.

Did you copy shmpipe.[ch] into your own application? Or are you using some other mechanism? If "wait-for-connection" is true, the sink should unblock as soon as at least one client is connected. -- Olivier Crête <a href="mailto:olivier.crete@collabora.com">olivier.crete@collabora.com</a> _______________________________________________ gstreamer-devel mailing list <a href="mailto:gstreamer-devel@lists.freedesktop.org">gstreamer-devel@lists.freedesktop.org</a> <a href="http://lists.freedesktop.org/mailman/listinfo/gstreamer-devel" target="_blank">http://lists.freedesktop.org/mailman/listinfo/gstreamer-devel</a> </blockquote></div>
