You create few sources, when their sink pad are added, you request a pad from the videomixer and set properties on it using g_object_set(). For gst-launch syntax. I have not found any documentation directly on this, though you'll find many example usage in: <A HREF="https://developer.gnome.org/gst-plugins-libs/1.0/gst-plugins-good-plugins-videomixer.html">https://developer.gnome.org/gst-plugins-libs/1.0/gst-plugins-good-plugins-videomixer.html</A> And also in the example I have given you. best regards, Nicolas </BODY> </HTML>
