The pipeline is correct, but you have to understand the actual code there. Tutorial 5 uses playbin, which implements the GstVideoOverlay interface. And that is used by Tutorial 5 to tell playbin where to render the video. A generic pipeline like yours does not implement GstVideoOverlay, so Tutorial 5 just fails. You have to change the code so that it uses the GstVideoOverlay interface of the video sink directly, see the documentation how to do that. -- Sebastian Dröge, Centricular Ltd · <a href="http://www.centricular.com" target="_blank">http://www.centricular.com</a> _______________________________________________ gstreamer-devel mailing list <a href="mailto:gstreamer-devel@lists.freedesktop.org" target="_blank">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>
