Comcut + encoding for linux, a start to a linux mediastrink

[Korny]

Please fix my title to Media Shrink


First of all, I'm not a programmer so the following bash script is really quite ugly but it works and I'm using ALL free utilities. This is just a start to the script any input is greatly appreciated I'm basically planning on using this in SJQ It currently uses 1 argument but I'm thinking about adding a second as a bitrate so it would basically be process.sh filename.mpg 2000
As for required software

Project-x - if your using ubuntu I installed it using package manager

Wine via package manager

Comskip I've learned that installing things in "home" directories can be a bad thing for permissions, since SJQ4 client does NOT run as my user account it couldn't access comskip when installed in the ~/.wine directory instead I've installed it in a non restricted folder.

ffmpeg I used a newer version as noted http://ubuntuforums.org/showthread.php?t=786095

HandbrakeCLI https://edge.launchpad.net/~stebbins...brake-releases

I'm currently running Ubuntu 10.10 32bit if you are running another distro you'll have to figure out how to get the required programs yourself.
Anyhow the start of my simple file. I haven't made it start cleaning up after itself so I apologize. Also the copy command and CD command at the start are not needed and can be removed. I use them because Sagetv locks the recording directory.
This thing keeps getting ugglier and uglier

#ffmpeg to remove unwanted audio stream
ffmpeg -i $filename -map $mapvarv -map $mapvara -vcodec copy -acodec copy -f vob ${filename%.*}maped.mpg
rm $filename
mv ${filename%.*}maped.mpg $filename
#rem comskip ensure
wine /media/Array1/TVprocess/comskip/comskip.exe /media/Array1/TVprocess/$filename

# ProjectX cutting
java -jar /usr/share/java/ProjectX.jar $filename -cut ${filename%.*}.mpg.Xcl

# FFmpeg remuxing PJX results
ffmpeg -i ${filename%.*}.m2v -i ${filename%.*}.$audiovar -vcodec copy -acodec copy -f vob ${filename%.*}muxed.mpg
# Encode
HandBrakeCLI -i ${filename%.*}muxed.mpg -e x264 -T -2 -b 2500 -r 29.97 -E copy -o ${filename%.*}.mkv

#clean up

mv ${filename%.*}.mkv ${filename%.*}dnd.mkv
rm ${filename%.*}.*
rm ${filename%.*}muxed.*
mv ${filename%.*}dnd.mkv ${filename%.*}.mkv

Also to get this script running in SJQ4
in executable /path/to/file/bash.sh
in arguments "$SJQ4_LAST_SEGMENT"
Make sure the file is executable
