<table cellpadding=3 cellspacing=0 border=0 width=100% bgcolor=white><tr valign=top><td width=100%> ok , if am using playbin in the application code , i can only get the clock used by playbin after setting its state to PLAYING. so i tried to : g_object_set(G_OBJECT(playbin),"video-sink",videosink,NULL); g_object_set(G_OBJECT(playbin),"audio-sink",osssink,NULL); gst_element_set_state(playbin , GST_STATE_PLAYING); GstClock *clock = gst_element_get_clock(playbin); gst_element_set_clock(videosink,clock); gst_element_set_clock(audiosink,clock); but still video is ahead of audio . in case of manually linking the elements(without using playbin) , av sync is ok any ideas --- On Wed 08/22, Stefan Kost < ensonic@hora-obscura.de > wrote: <BLOCKQUOTE style="PADDING-LEFT: 7px; MARGIN-LEFT: 7px; BORDER-LEFT: orange 2px solid">From: Stefan Kost [mailto: ensonic@hora-obscura.de] To: gstreamer-devel@lists.sourceforge.net Date: Wed, 22 Aug 2007 16:17:38 +0200 Subject: Re: [gst-devel] problem in using playbin hi, can you please ensure that your mail get send in a readable format. Regarding the topic - I you have a/v sync issues then check which clock is used and ensure that your sinks render based on the same time information.
