- README for libdvdcss, a portable abstraction library for DVD decryption
- $Id$
-
-
- 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.
- 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.
- This is the default method,
- DVDCSS_VERBOSE={0|1|2}: libdvdcss verbosity
- 0: no error messages, no debug messages (this is the default)
- 1: only error messages
- 2: error and debug messages
-
-
- Troubleshooting
- ===============
-
- A mailing-list has been set up for support and discussion about
- libdvdcss. Its address is :
-
- <libdvdcss@videolan.org>
-
- To subscribe, send a mail to <listar@videolan.org> with the following
- words in the mail body :
-
- subscribe libdvdcss
-
- To unsubscribe, do the same with the words :
-
- unsubscribe libdvdcss
-
-
- 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.
