libdvdcss

libdvdcss is a simple library designed for accessing DVDs like a block device without having to bother about the decryption.

Features

Portability. Currently supported platforms are GNU/Linux, FreeBSD, NetBSD, OpenBSD, Haiku, Mac OS X, Solaris, QNX, OS/2, and Windows NT 4.0 SP4 (with IE 5.0) or later.
Simplicity. A DVD player can be built around the libdvdcss API using no more than 4 or 5 library calls.
Freedom. libdvdcss is released under the General Public License, ensuring it will stay free, and used only for free software products.
Just better. Unlike most similar projects, libdvdcss does not require the region of your drive to be set.

The latest version of libdvdcss is 1.4.3.

On Debian and Ubuntu, you can install libdvdcss via libdvd-pkg helper package:

sudo apt install libdvd-pkg

And by running the following command, which will download, build and install the latest libdvdcss source to your machine:

sudo dpkg-reconfigure libdvd-pkg
