The Ripinator!!!

Motivation:
My fiance and I have a stack of DVDs. They’re dusty and inconvenient. I wanted to rip them to my network storage so I can easily watch them from my Boxee Box. It’s not that I’m lazy, but I hate doing repetative things if I can automate it.

Overview:
I’m using Perl with Win32::SerialPort to control the autoloader. I’m using Win32::DriveInfo to get the volume name of the DVD. I’m using TMDB on the off chance the volumename will pull up the movie. I’m using DVDFab 8 to rip mainmovie to an ISO file. I’m using Handbrake to encode to iPad preset. In my testing, this looks just as good as the ISO file and uses only 20-30% of the space.

To use I batch together either all movies, or all TV shows. I rip my movies into my mapped network drive, V:\queue\ and my TV shows into V:\TV_queue\
I have my faster computers actually do the encoding. Multiple computers. I map the V:\ drive to the same fileshare. I encode my movies to V:\Encoded\ and my TV shows to V:\TV_Encoded\

ripinator.pl
Main program. It requires gripper, ripper, and traycmds. I broke this into multiple pieces to make it easier for me to keep track of.
Enumerates all CD/DVD drives attached to the computer and iterates through them probing the gripper arm to each tray. If a tray is detected, the drive number and drive letter are noted.
It then checks the levels of the bins.
If there are discs in the desginated input bin, it will load them into the drives and start the ripper.pl script
If there are discs done ripping, it will unload them into either the reject bin, or the output bin, depending on the exit code
This will continue until either something crashes, a disc is completely unreadable, or there are no more discs left to rip.

Back Story:
A few years ago, we had a Rimage DVD production robot at work. I dubbed it Trogdor the Burninator. Rimage had some pretty scummy practices… The ink cartridges are standard HP cartridges, but had a little tag in the label that will keep the software from loading if you don’t buy the Rimage branded cartridges. I’m sure they would have gouged even more if they could think of a way to do it. So we replaced it with a newer, nicer one from Primera. It was an improvement in pretty much every way. I got the old one since no one else wanted it. SCORE!

I took it up as a project again. I had saved the old software from Rimage and was able to get it to run for 30 days between wiping and reloading the computer it was attached to. This was enough time to determine that the connection between the printer and the RAS 13 autoloader was RS232 serial. I sniffed the traffic between long enough to figure out which commands did what, and what replies meant. This is by no means definitive, but it’s enough to use an otherwise useless piece of equipment.
