 hi ,yeah i have a custom video sink where i call the display frame api  of hardware decoder  in show_frame function   i have  initilaised the basesink's  render , preroll method to show_frame function  i am also having a get_times function in the videosink for audio i am using  osssink.  ok if the videosink is incorrect  then why the manual pipeline works fine with av sync(if i link the elements by code)one more thing .........       since the video decoder already puts decoded data in hardware frame buffer , so i am just passing fake buffer ( 16 byte fake data)  with timestamp and duration (from qtdemux)  to downstream element from video decoder .      can u help me in resolving this issue       --- On Tue 08/21, Andy Wingo < wingo at pobox.com > wrote:From: Andy Wingo [mailto: wingo at pobox.com]To: digitaldsp at excite.comCc: gstreamer-devel at lists.sourceforge.netDate: Tue, 21 Aug 2007 22:55:01 +0200Subject: Re: [gst-devel] problem in using playbinHello,"pritesh" writes:> 
but av sync is missing in paused state itself some video frames are displayed In the paused state, no audio is played, so sync is not a problem> and when i set state to playing the audio lags video This can only be the case if either (1) your timestamps are incorrect,or (2) you have custom sinks that are not respecting the clocks.> but when i create the pipeline using decodebin only then av sync is> proper is this a preroll problem or videosink problemSeems to indicate problems in your sinks.Regards,Andy.-- http://wingolog.org/
