If you do that you'll loose A/V sync. Whatever sync you choose on the pipeline must receive proper timestamps. It's OK to write a dec+sink elements, that's what we use in Maemo, but they need to act as sinks (inherit from basesink) so that they handle pre-rolling and A/V sink, etc. -- Felipe Contreras ------------------------------------------------------------------------------ This SF.net email is sponsored by: SourcForge Community SourceForge wants to tell your story. http://p.sf.net/sfu/sf-spreadtheword _______________________________________________ Gstreamer-embedded mailing list Gstreamer-embedded@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/gstreamer-embedded
