Hi Marc, Thanks for your kind attention. Actually I wanted a real time video overlay; Consider the situation; I started playing a 2 hour long video. After 10 minutes, I want to overlay another video (or image) on a small area in the screen without interrupting or stopping the first video. Is that possible? Can you send any API available in GStreamer for doing that? <div class="gmail_quote">On Wed, Jun 10, 2009 at 5:24 PM, Marc Leeman <<a href="mailto:marc.leeman@gmail.com">marc.leeman@gmail.com</a>> wrote: <blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> <div class="im">> How can I do real-time video mixing with gstreamer?

We call it the 'hide-the-pr0n' pipeline. If you mention pr0n in a presentation with engineers, you always get their full attention. -- greetz, marc The earth is like a tiny grain of sand, only much, much heavier. crichton 2.6.26 #1 PREEMPT Tue Jul 29 21:17:59 CDT 2008 GNU/Linux -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.6 (GNU/Linux) iD8DBQFKL57cUQpj09NWLeERAmpGAKCLjE0lxlcXyFNmLHMnJs7UsbFpLQCfTDCT skot1Y+L3kTzdBGgLwkvprY= =NtB4 -----END PGP SIGNATURE----- ------------------------------------------------------------------------------ Crystal Reports - New Free Runtime and 30 Day Trial Check out the new simplified licensing option that enables unlimited royalty-free distribution of the report engine for externally facing server and web deployment. <a href="http://p.sf.net/sfu/businessobjects" target="_blank">http://p.sf.net/sfu/businessobjects</a> _______________________________________________ gstreamer-devel mailing list <a href="mailto:gstreamer-devel@lists.sourceforge.net">gstreamer-devel@lists.sourceforge.net</a> <a href="https://lists.sourceforge.net/lists/listinfo/gstreamer-devel" target="_blank">https://lists.sourceforge.net/lists/listinfo/gstreamer-devel</a> </blockquote></div>
