Ok, here's a couple of scripts I have been using very successfully.
Make sure you have run ProjectX once and have the X.ini file.
This first one was mostly another's work, I forget who! (THANK YOU). I
added a command-line option which I use exclusively (-m) because I want
just a mpg file that I can use in DVDStyler later.
-------------nuv2dvd.sh--------------
#!/bin/bash
# Just a sample script. Use at your own risk!
#
# Usage: nuv2dvd [-m] [-d] [-r<N>] <file1> [<file2> <file3>...]
#
# -d Only make a dvd directory structure: do not burn. Resulting
# file structure can be found in ./dvd.tempdir/dvd
# -r<N> Requantize video only using tcrequant with requantization
# factor N. This will reduce the space taken for video by a
# factor of N. E.g. -r2.0 will result in video that takes
# about half the original space. Does not affect audio.
#
# -m mplex only - do not create the DVD structure
DEVICE="/dev/sr0" # DVD burner device. Make sure it's umounted!
STREAM_BASE="stream"
PROJECTX_BIN="/myth/burn/ProjectX.jar" # Compiled ProjectX.jar
PROJECTX_INI="/myth/burn/X.ini" # Use an unchanged default X.ini!
TEMP_DIR="/myth/burn/temp"
FINAL_DIR="/myth/video" # only for just mplexing
function Error ()
{
echo "ERROR: $1"
exit 1
}
mkdir $TEMP_DIR || Error "Could not make tempdir: $TEMP_DIR"
COUNT=0; RVAL=""; BURN="yes"; JUSTMPLEX="no"
for ARG in $*
do
echo "Argument: $ARG"
case $ARG in
-r*) # Requantize
RVAL=${ARG##*-r}
echo "Requantization factor: $RVAL"
;;
-d) # Just write dvd file structure
BURN="no"
echo "Burn: $BURN"
;;
-m) # Just mplex
BURN="no"
JUSTMPLEX="yes"
echo "Just mplex: $JUSTMPLEX"
;;
*) # Process the file
./getcutlist.sh $ARG
if [ -s $ARG ]; then
echo "Demultiplexing file: $ARG"
let "COUNT=$COUNT+1"
java -jar $PROJECTX_BIN -c $PROJECTX_INI -p cutlist2.txt
-n "$STREAM_BASE$COUNT" -o $TEMP_DIR $ARG
BNAME="$TEMP_DIR/$STREAM_BASE$COUNT"
if [ ! -z $RVAL ]; then
mv "$BNAME.mpv" "$BNAME.tmp.mpv"
mkfifo "$BNAME.mpv"

if [ $JUSTMPLEX = "no" ]; then

else
outname="$TEMP_DIR/$(basename $ARG).mpg"
mplex -f 8 -V -o "$outname" "$BNAME.mpa" "$BNAME.m2v"
fi
else
Error "Not a good file: $ARG"
fi
;;
esac
done
if [ $JUSTMPLEX = "no" ]; then
echo "Creating dvd file structure with dvdauthor..."
dvdauthor -o "$TEMP_DIR/dvd" -f "$TEMP_DIR/$STREAM_BASE"*.mpg
dvdauthor -o "$TEMP_DIR/dvd" -T
if [ $BURN = "yes" ]; then
echo "Burning file structure to dvd device: $DEVICE"
growisofs -Z $DEVICE -dvd-video "$TEMP_DIR/dvd"
fi
echo "Cleaning up temporary files..."
rm -v "./$TEMP_DIR/$STREAM_BASE"*
if [ $BURN = "yes" ]; then
rm -rv "$TEMP_DIR/dvd"
rmdir -r "$TEMP_DIR"
fi
else
echo "$outname"
mv "$outname" "$FINAL_DIR"
rm -r "$TEMP_DIR"
fi
--------------------------------
This next one is called by the above. It gets the cutlist. It could
theoretically be inline...
---------getcutlist.sh---------
#!/bin/sh
infile=$1
mysqluser='mythtv'
mysqlpass='mythtv'
# I definitely want to use pretty links, so...
if [ -L $infile ]; then
infile=$( basename $( readlink $1 ))
fi
# Strip stuff out of the filename
channel=$( echo $infile | cut --delimiter="_" -f 1 )
starttime=$( echo $infile | cut --delimiter="_" -f 2 )
endtime=$( echo $infile | cut --delimiter="_" -f 3 | cut --delimiter="_"
-f 1 | cut --delimiter="." -f 1 )
echo "(2) use Frame number for cuts" > cutlist.txt
mysql -u$mysqluser -p$mysqlpass mythconverg -s -B --exec \
"select IFNULL(recorded.cutlist,'') from recorded where
recorded.chanid=$channel and recorded.starttime=$starttime and
recorded.endtime=$endtime;" >> cutlist.txt
sed -e "s/\\\n/\n/g; s/ - /\n/g; s/^0\n//g" cutlist.txt > cutlist2.txt
--------------------------------
I wonder if the MythBurn invertcutlist.pl file would be a better
solution than using the ^0\n edit as above... I haven't investigated.
Comments? Improvements?
