#
#USAGE:######################
#This Sript shall be called as a MythTv user job like the following:
#/path/to/umwandeln.sh "%FILE%" "%SUBTITLE%" "%CHANID%" "%STARTTIME%" "%TITLE%"
#############################
#
#
#REQUIREMENTS################
# U need to have the following programs installed:
# mediainfo: http://mediainfo.sourceforge.net/
# handbrake with dependencies: http://www.handbrake.fr

###Define some basic varibles
scriptstarttime=$(date +%F-%H%M%S)
file="$1"
subtitle="$(echo "$2" | sed 's/(//g' | sed 's/)//g' | sed 's/://g')"
#| sed 's///_/g' | sed 's/?//g' | sed s/"'"//g
chanid="$3"
starttime="$4"
title="$(echo "$5" | sed 's/(//g' | sed 's/)//g' | sed 's/:/_/g' | sed 's%/%_%g')"
#| sed 's/"/"/_/g' | sed 's/?//g' | sed s/"'"/""/g
logdir="/opt/mythtv/transcodelogs"
logfile="$logdir/$scriptstarttime-$title.log"
touch "$logfile"
chown mythtv:mythtv "$logfile"
chmod a+rw "$logfile"
errormail="youremail@adress.com" # this email adress will be informed in case of errors
mythrecordingsdir="/some/path" # specify directory where mythtv stores its recordings
outdir="/where/you/want/it" # specify directory where you want the transcoded file to be placed
filename=$title.mkv" # can be customized
if [ -f "$outdir/$filename" ]
# do not overwrite outfile, if already exists, change name
then
filename="filename-$scriptstarttime"
fi
outfile="$outdir/$filename"

###Do some logging
echo "Transcodejob $title starting at $scriptstarttime" >> "$logfile"
echo "Original file: $mythrecordingsdir/$file" >> "$logfile"
echo "Target file: $outfile" >> "$logfile"
echo "ChanId: $chanid Zeit: $starttime" >> "$logfile"

    then

    echo "Error prior to encoding at $scriptstoptime" >> "$logfile"
