Description:

libdvdcss is a simple library designed for accessing DVDs like a block device
without having to bother about the decryption. The important features are:
* Portability: currently supported platforms are GNU/Linux, FreeBSD, NetBSD,
OpenBSD, BSD/OS, BeOS, Windows 95/98/ME, Windows NT/2000/XP, MacOS X,
Solaris, HP-UX and OS/2.
* Adaptability: unlike most similar projects, libdvdcss doesn't require the
region of your drive to be set and will try its best to read from the disc
even in the case of a region mismatch.
* Simplicity: a DVD player can be built around the libdvdcss API using no
more than 6 library calls.
