Hi, I am having mpeg2 file.My mpeg2 file is of 29.97 fps with 720*480 with mp2 audio of 192Kbps and 48KHz from h/w encoder.
I want to convert to DVD-video format.Since my mpeg2 does not contain NAV stream. So i used mplex. Intially i demuxed mpeg by using mpeg2desc (which comes with dvdauthor tool) to separate video and audio. Then i tried with 1- mplex -V -f 8 -O $OFFSET'mpt' -o myvideo.mpg myvideo.m2v myvideo.mp2 OFFSET i got from mpeg2desc by using -m option. I could able to play it. But after sometime A/V is not synced. Seems audio comes bit earlier than video. 2- Tried with OFFSET/90 mpt (I found Mr. Scott told precission is lost link: http://sourceforge.net/mailarchive/message.php?msg_id=6583939 ) But with this also a/v is not synced. 3- By making equal Video delay and Audio delay also same problem Could anyone suggest me, what i have to do ? Manoj Here is output of mplex.
