Converting DVD to x264 w/ Mencoder out of sync?


hi
i'm trying to backup my dvd to x264 with ac3 sound however sound become out of sync by 5 seconds

Is the a better way?

Code:
#here i export to the ac3 sound
mplayer k9-1.vob -aid 129 -dumpaudio -dumpfile k9-1.vob.ac3

#my first encoding pass
mencoder -v\
        k9-1.vob\
        -vf pullup,softskip,crop=720:448:0:16\
        -ovc x264 -x264encopts subq=4:bframes=3:b_pyramid:weight_b:turbo=1:pass=1:psnr:bitrate=1200\
        -nosound\
        -of rawvideo\
        -o k9-1.vob.264

#my second encoding pass
mencoder -v\
        k9-1.vob\
        -vf pullup,softskip,crop=720:448:0:16\
        -ovc x264 -x264encopts subq=4:bframes=3:b_pyramid:weight_b:turbo=1:pass=2:psnr:bitrate=1200\
        -nosound\
        -of rawvideo\
        -o k9-1.vob.264

#the MP4 container doesnt support ac3 so just the video is added to an MP4 video container below
MP4Box -add k9-1.vob.264 k9-1.vob.264.mp4

#Matroska supports Mp4 video and x264 in the same file 
#below is where i create the final Audio Video file.
mkvmerge -o k9-1.vob.264.mp4.mkv k9-1.vob.264.mp4 k9-1.vob.ac3

Hmm - I don't know what is causing your problem, but if you are willing to try MP3 encoding, try this commandline with MEncoder to rip the DVD and see if the resulting file has better audio performance (this is a single pass type setup, and requires LAME):

mencoder dvd://1 -alang en -o output.avi -oac mp3lame -lameopts vol=8 -ovc lavc -ffourcc DX50 -lavcopts vcodec=mpeg4:aspect=1.78/1:vbitrate=1800:vrc_eq=tex:naq:ilme:trell:cbpreme=2:subq=8:keyint=132:mbd=1:qns=3:vme=4:dia=3 -noskip

If you find that the resulting file is too "loud" make -lameopts vol=8 something less (like -lameopts vol=6) or if it is too "soft" make vol = 8 something even higher.

I'm willing to bet the above has a good change of solving your audio problem. I've never used two pass ripping or splitting off of the audio track - why exactly do you want to do it that way?
