Tweaking and HD

So after successfully automating my perfect TV setup with minimal human interaction, I decided to take the next logical step and prepare for more HD content, seeing as how Lost is back, and I’m on the late shift so I always have to watch it after it has aired on cable. I cobbled together a script from a number of different scripts I had for dealing with various media files, and I also wrote a little while loop to prevent my server from having too many instances of ffmpeg running at once. Here is the script, below:

### Transcode 720p H264 mkv files for the Apple TV

if [ -z $1 ]; then
echo “Usage: `basename $0` filename”
exit 0

# Wait while any other ffmpeg processes are running
while [ -n “$(ps -ef | grep ffmpeg | grep -v grep)” ];
echo -e “\n[$(date +%b\ %d\ %Y:\ %H:%M:%S)]\nffmpeg is currently working…”
sleep 300

# Get the beginning time from the date cmd.
START=$(date +%D\ %T)

# Email us that the next process has begun
echo -e “About to start transcoding $1 at $START” > /tmp/emailmessage.txt

# ffmpeg cmd
ffmpeg -y -i $1 -threads 2 -s 1280×720 -aspect 1280:720 -r ntsc-film -vcodec libx264 -g 150 -qmin 8 -b 4500k -level 31 -loop 1 -sc_threshold 40 -partp4x4 1 -rc_eq ‘blurCplx^(1-qComp)’ -refs 2 -qmax 51 -maxrate 4500k -bf 1 -keyint_min 40 -async 1 -acodec libfaac -ar 48000 -ac 2 -ab 384k $1.mp4

# Get the ending time of the transcode process from the date cmd.
END=$(date +%D\ %T)

# Inform us with an email
echo “Transcoding of $1 was started on $START and completed on $END.” > /tmp/emailmessage.txt
mv -v $1 /mkvs


## Look for HD files and mv -v them over to the NFS Share on lunchbox
## Look for the shows we watch, and move files to the right place.


if [[ “$TranscodedFile” =~ lost* ]] || [[ “$TranscodedFile” =~ Lost* ]]; then
LostFile=$(echo $TranscodedFile | sed ‘s/\(.*ost\).\([Ss][0-9]*[Ee][0-9]*\).mkv.*/\2./’)
echo “[*] A new episode of Lost (in HD!) is ready for your enjoyment: $LostFile” > /tmp/emailmessage.txt && sleep 2
mv -v “$TranscodedFile” $HDstorageDir/Lost/$LostFile
exit 0
elif [[ “$TranscodedFile” =~ Heroes* ]] || [[ “$TranscodedFile” =~ heroes* ]]; then
HeroesFile=$(echo $TranscodedFile | sed ‘s/\(.*oes\).\([Ss][0-9]*[Ee][0-9]*\).mkv./\2./’)
echo “[*] A new Episode of Heroes (in HD!) is ready for your enjoyment: $HeroesFile” > /tmp/emailmessage.txt && sleep 2
mv -v “$TranscodedFile” $HDstorageDir/Heroes/$HeroesFile
exit 0
elif [[ “$TranscodedFile” =~ Battlestar* ]] || [[ “$TranscodedFile” =~ battlestar* ]]; then
BattleFile=$(echo $TranscodedFile | sed ‘s/\(.*tica\).\([Ss][0-9]*[Ee][0-9]*\).mkv./\2./’)
echo “[*] A new Episode of Battlestar Galactica (in HD!) is ready for your enjoyment: $BattleFile” > /tmp/emailmessage.txt && sleep 2
mv -v “$TranscodedFile” $HDstorageDir/Battlestar\ Galactica/$BattleFile
exit 0
elif [[ “$TranscodedFile” =~ The.Office* ]] || [[ “$TranscodedFile” =~* ]]; then
OfficeFile=$(echo $TranscodedFile | sed ‘s/\(.*ffice\).\([Ss][0-9]*[Ee][0-9]*\).mkv./\2./’)
echo “[*] A new Episode of The Office (in HD!) is ready for your enjoyment: $OfficeFile” > /tmp/emailmessage.txt && sleep 2
mv -v “$TranscodedFile” $HDstorageDir/iThe\ Office/$OfficeFile
exit 0
elif [[ “$TranscodedFile” =~ 24* ]]; then
TwentyFourFile=$(echo $TranscodedFile | sed ‘s/\(.*4\).\([Ss][0-9]*[Ee][0-9]*\).mkv./\2./’)
echo “[*] A new Episode of 24 (in HD!) is ready for your enjoyment: $TwentyFourFile” > /tmp/emailmessage.txt && sleep 2
mv -v “$TranscodedFile” $HDstorageDir/24/$TwentyFourFile
exit 0
echo “[+] $1 does not match our TV shows, pushing it to /storage/HD Movies on lunchbox” > /tmp/emailmessage.txt
mv -v “$TranscodedFile” “/storage/HD\ Movies/$(echo $i | sed -e ‘s/\(.*\).720.*\(.mkv\)\(.mp4\)/\1\3/’)”

exit 0

Hopefully someone finds this useful for their own media management purposes. Basically the script just waits until ffmpeg isn’t running, emails me that it is starting, transcodes the HD file for playback on the AppleTV, emails me when transcoding is done, and then uses sed (string editor) to chop of the bits of the filename I don’t want showing up, and places it in the correct directory depending on the name of the show. Also, if the filename doesn’t match any show, it goes to the HD Movies directory. In addition, when it’s all over, it emails me to let me know I’ve got some new media to enjoy!
