i've been looking how to encode vob files into divx avi files, and
without fail following any of the howto's i google resulted in failure.
i have mencoder installed, vobcopy. i have the vob files and they play
perfectly. what do i need to execute to convert them into mpeg4 avi files?
So you need to fit a DVD onto a CD;)
Here's what I did. For each .vob file
mencoder -oac lavc -ovc lavc -lavcopts \
acodec=mp3:abitrate=192:vcodec=mpeg4:vbitrate=800 -vf scale=512:384 \
-o your.avi your.vob \
then concatenate the avi's
cat your1.avi your2.avi ... yourn.avi > all.avi
and then fix the resulting avi with
mencoder -idx all.avi -ovc copy -oac copy -o result.avi
HTH,
it doesn't have to fit on a cd, just a single layer dvd. so only a small
reduction in size is needed.
initally when i tried your command it errored whinging about not having
a subfont.tff, so i just pointed it to a generic ttf i had, it then
bombed out with this
mencoder -oac lavc -ovc lavc -lavcopts \
acodec=mp3:abitrate=192:vcodec=mpeg4:vbitrate=800 -font
/usr/X11R6/lib/X11/fonts/bitstream-vera/Vera.ttf \
-o 1.avi the_video_you_wanted1-1.vob \
