 ok , i will check on videosink part , but what about timestamp and duration of video buffers  right now i am using timestamp and duration given by qtdemux   since the decoded data is already in frame buffer , i am just passing fake gstbuffer  with timestamp , duration, and caps but with some fake data   does the timestamp or duration neeeds to be adjusted according to decoder speed (fps), which is quite fast  --- On Sun 08/12, Wim Taymans < wim.taymans at gmail.com > wrote:From: Wim Taymans [mailto: wim.taymans at gmail.com]To: digitaldsp at excite.comCc: gstreamer-devel at lists.sourceforge.netDate: Sun, 12 Aug 2007 17:17:00 +0200Subject: Re: [gst-devel] av sync issue with hardware decoderOn Sun, 2007-08-12 at 11:06 -0400, pritesh wrote:Are you subclassing the videosink from GstVideoSink? if you do this andtimestamp the video buffers correctly all should work fine.Wim> hi all,> on arm board i have a hardware h264 decoder . which has exposed> decode , postprocess ,
