  4. Hi all of you, i am developing video-audio record as a module in my app. before i used ffmpeg (this free, open source) to do. but the output contains video and audio can not be synchronize .

I would like to use another sample (Record Video_Audio with synchronize), anyone can give me sample? Or, if i still use MPEG Record from sourceforge, has any way to replace XVID codec by codec support from ffmpeg.??? Many thank for any help. [Edited by - toan1982 on May 29, 2007 9:19:56 PM]
