It is almost the same but better in some ways of its core architecture. Gstreamer 0.10 is maintained only for legacy reasons and because some plugins are not ported yet (if I am not mistaken). There is also an updated tutorial for gstreamer 1.0: <a class="moz-txt-link-freetext" href="http://gstreamer.freedesktop.org/data/doc/gstreamer/head/gst-plugins-base-libs/html/gst-plugins-base-libs-gstvideooverlay.html">http://gstreamer.freedesktop.org/data/doc/gstreamer/head/gst-plugins-base-libs/html/gst-plugins-base-libs-gstvideooverlay.html</a> On 08/08/2013 10:31 PM, Marlon Smith wrote: </div> <blockquote cite="mid:1375997469.2170.13.camel@marlon-Z68X-UD3H-B3" type="cite"> <meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1"> <meta name="GENERATOR" content="GtkHTML/3.32.2"> Hi everyone, I'm using Ubuntu 12.04 for the Wandboard, and I'm trying to get a Qt application to play a video with GStreamer.
