README for libdvdcss, a portable abstraction library for DVD decryption
|
|
|
|
|
|
Introduction
|
|
============
|
|
|
|
libdvdcss is part of the VideoLAN project, a full MPEG2 client/server
|
|
solution. The VideoLAN Client can also be used as a standalone program
|
|
to play MPEG2 streams from a hard disk or a DVD.
|
|
|
|
|
|
Building and Installing libdvdcss
|
|
=================================
|
|
|
|
See the INSTALL or INSTALL.libdvdcss file for this.
|
|
|
|
Running lidvdcss
|
|
================
|
|
|
|
The behaviourof the library can be affected by changing two environment
|
|
variables:
|
|
DVDCSS_METHOD={title|disc|key}: method for key decryption
|
|
title: decrypted title key is guessed from the encrypted sectors of
|
|
the stream. Thus it should work with a file as well as the
|
|
DVD device. But it sometimes takes much time to decrypt a title
|
|
key and may even fail. With this method, the key is only checked
|
|
at the beginning of each title, so it won't work if the key
|
|
changes in the middle of a title.
|
|
This is the default method,
|
|
disc: the disc key is first cracked ; then all title keys can be
|
|
decrypted instantly, which allows us to check them often,
|
|
key: the same as "disc" if you don't have a file with player keys at
|
|
compilation time. If you do, the decryption of the disc key
|
|
will be faster with this method. It is the one that was used by
|
|
libcss.
|
|
DVDCSS_VERBOSE={0|1|2}: libdvdcss verbosity
|
|
0: no error messages, no debug messages,
|
|
1: only error messages (this is the default)
|
|
2: error and debug messages
|
|
|
|
|
|
Troubleshooting
|
|
===============
|
|
|
|
A mailing-list has been set up for support and discussion about vlc and
|
|
libdvdcss. Its address is :
|
|
|
|
<vlc@videolan.org>
|
|
|
|
To subscribe, send a mail to <listar@videolan.org> with the following
|
|
words in the mail body :
|
|
|
|
subscribe vlc
|
|
|
|
To unsubscribe, do the same with the words :
|
|
|
|
unsubscribe vlc
|
|
|
|
|
|
When reporting bugs, try to be as precise as possible (which OS, which
|
|
distribution, what plugins you were trying, and so on).

Resources
|
|
=========
|
|
|
|
The VideoLAN web site at http://www.videolan.org/ is a good start for
|
|
information about MPEG and DVD playing. Have a look at the documentation
|
|
section, as well as the bookmarks.
