Take a look at the code available here to get you started: <A HREF="http://code.google.com/p/ossbuild/source/browse/trunk/Main/GStreamer/Source/gstreamer/tools/gst-player.c#2407">http://code.google.com/p/ossbuild/source/browse/trunk/Main/GStreamer/Source/gstreamer/tools/gst-player.c#2407</A> Follow the callback into playbin_element_added() on line 1427, then into uridecodebin_element_added() on line 1450, then into decodebin_element_added() on line 1471, and finally into examine_element() on line 506. The property is explicitly set on line 514. It's rather ugly, but it does the trick. _______________________________________________ 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">http://lists.freedesktop.org/mailman/listinfo/gstreamer-devel</A> </PRE> </BLOCKQUOTE> </BODY> </HTML>
