You know when I didn't get help for some time, I had lost my hope and abandon it. 2 second is considerable time. Anyway, I am sorry for my sily question, but I don't understnad what you mean by "narrow it down"? Also how can I "Check if you receive the material properly timestamped"?. Thank you again for your help. - Zelalem S. > Date: Sat, 18 Jul 2009 19:03:10 +0300 > From: ensonic@hora-obscura.de > To: gstreamer-devel@lists.sourceforge.net > Subject: Re: [gst-devel] How can I synchronize video and audio > > Zelalem Sintayehu schrieb: > > Hi guys, I wanted to record video coming from network into avi file, > > and wrote some code.
