[mythtv-users] Automatically Transcoding the Commercials Away

Hash: SHA1

I've been reading the code provided in the wiki and I just wanted to 
make sure I was doing things correctly before potentially messing up my 
files and/or database.  I have a row of hashes (#) where I'm going to 
change up the script.


#!/bin/sh
VIDEODIR=$1
FILENAME=$2
# Sanity checking, to make sure everything is in order.
if [ -z "$VIDEODIR" -o -z "$FILENAME" ]; then
~        echo "Usage: $0 <VideoDirectory> <FileName>"
~        exit 5
fi
if [ ! -f "$VIDEODIR/$FILENAME" ]; then
~        echo "File does not exist: $VIDEODIR/$FILENAME"
~        exit 6
fi
# The meat of the script. Flag commercials, copy the flagged commercials to
# the cutlist, and transcode the video to remove the commercials from the
# file.

#I want to delete this section since I already commercial flag all of my 
recordings and will only
#transcode certain ones
#######################################################################################3
mythcommflag -f $VIDEODIR/$FILENAME
ERROR=$?
if [ $ERROR -gt 126 ]; then

mythtranscode --honorcutlist --showprogress -i $VIDEODIR/$FILENAME -o

~               SELECT
~                       CONCAT( chanid, starttime )
~               FROM
~                       recorded
~               WHERE
~                       basename = '$FILENAME'
~       );
#############################################################################
SET
~        cutlist = 0,
~        filesize = $(ls -l $VIDEODIR/$FILENAME | awk '{print $5}')
WHERE
~        basename = '$FILENAME';
EOF
~        exit 0
else
~        echo "Clearing cutlist failed for ${FILENAME} with error $ERROR"
~        rm /usr/video/$FILENAME.tmp
~        exit $ERROR
fi



Also, once this is all put into a file - do I put it into /usr/local/bin 
?  And how do I run it as a user job?

Thanks!
