Building a DVD player/ripper

[swappo]

Hello,

I am working on a project where I am building a DVD player/ripper to rip movies onto my hard drive to play them on my computer as well as my home theater. I code in C/C++ and am building the gui with gtk+. The problem I am having is finding background information on how to write the code to remove the encryption from a DVD. When I search google, all I am coming up with are programs like anydvd and dvd decrypter. I need background info on how to write the algorithms that do the decryption. Does anybody know where I can find more info on this? Thanks.

Have you thougth of using MEncoder / MPlayer as the ripper/player engine for your program and just write front end for them your self? Might save a lot of trouble.

Yeah, I could do that. However, I would still need to figure out how to handle the encryption on the disk. I don't believe that MEncode/MPlayer handles encryption.

MEncoder can use libdvdcss to get the content from the disc. I have used it myself few times. I'm not sure what kind of encryption you are talking about but I guess there's only one way to find out if it does the job for you. Google rip DVD MEncoder and try it.

Well, it uses libdvdcss, so you might want to to look into how to use libdvdcss. I've never had any problem with a DVD that I've ripped with it.

On the other hand, MEncoder is already an extremely powerful application, and extremely scriptable. There was at least one gtk front-end for it I can remember called "acidrip" and there's another Win32 program that uses it called MeGUI. Perhaps your efforts might be better spent developing a an up-to-date GTK gui for MEncoder, as acidrip is pretty out-of-date.
