Post subject:  Export NUV To KVCD
Here's a script that I've modified a bit. I've customized it so it can be used to generate KVCD compatible mpeg files. Using this script you can fit about an hour and a half of really good quality video on ONE CD --which then can be played in most? standalone DVD players.

In order to use this script for NUV files you need to have a patched version of mplayer.
The patched version of mplayer that comes with knoppmyth isn't recent enough so you'll need to apply this patch:

http://dijkstra.csh.rit.edu:8088/~mdz/mythtv/

to a recent version (I used MPlayer 1.0pre4-3.3.3)

Once you have patched (I got a couple of errors when patching --the patch is for an older version of mplayer, but still worked) , compiled and installed mplayer you invoke the script like this:

./movie output movie.nuv (I called it movie, guess you can call it whatever you want...)

or if you install the movie script in /usr/bin just:

movie output movie.nuv


the script does a lot of other stuff --stuff I disabled during testing. If you get it working good you might think about re-enabling some of these things.

anyway, here's the script:
#!/bin/bash
#
# Copyright (C) 2003-2038 russiansexpat
#
# script: mpeg(1,2,3,4) conversion to (S,X)VCD with quantisation matrix
# and auto-splitting into multiple CDs and writing them.
#
# requires: mencoder(1.0pre3) mplayer mplex vcdimager cdrdao
# optional: normalize sox toolame(0.2k)
#
# does not require: microsoft. This script has not been tested on animals.
#
# further modified by dtm (#mplayer)
# and even further modified by DogBoy (#knoppmyth)
#
# use of this script with knoppmyth or mythtv _requires_ a version of mplayer that
# has been patched for .nuv
# patch available here: http://dijkstra.csh.rit.edu:8088/~mdz/mythtv/
# since this script also requires the use of at least mencoder(1.0pre3)
# and the patch was written for an older version of mplayer,
# you will have to apply the patch to the newer version
# this _does_ result in a couple of errors while patching but
# the resulting patched version of mplayer _did_ compile and was able to play .nuv
# it also installed in /usr/local/bin/mplayer so if used with knoppmyth you'll have two versions of mplayer
# and mencoder installed as the normal mplayer for knoppmyth resides at /usr/bin/mplayer
# anyway, the path in this script reflects this
# again... this script will only work with a recent version of mplayer patched for .nuv

for exe in mencoder mplayer mplex vcdimager cdrdao; do
if [ -z "`which $exe`" ]; then
echo "ERROR: $exe must be in your path $PATH"
exit 1
fi
done
