Yes you can, create seperate stream sinks and mix them with videomixer. One should be v4lsrc other ximagesrc. That would be right direction. <div class="gmail_quote">2014 spal. 22 00:13 "Paolo Bolzoni" <<a href="mailto:paolo.bolzoni.brown@gmail.com">paolo.bolzoni.brown@gmail.com</a>> rašė: <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">Dear list, In few weeks I have to do a presentation via the Internet. I was wondering if using gstreamer it is possible to compose the content of a window (for example a browser displaying the slides) and the webcam. Finally I was thinking to send this video stream to a v4l2loopback to use it in any program able to use the webcam. It is possible? I found the documentation a little daunting, but I will be happy to study it a little if pointed in the right direction. your faithfully, Paolo _______________________________________________ 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>
