The important features - * are: - * \li portability: currently supported platforms are GNU/Linux, FreeBSD, - * NetBSD, OpenBSD, BSD/OS, BeOS, Windows 95/98, Windows NT/2000, MacOS X, - * Solaris, HP-UX and OS/2. - * \li 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. - * \li simplicity: a DVD player can be built around the \e libdvdcss API using - * no more than 4 or 5 library calls. - * - * \e libdvdcss is free software, released under the General Public License. - * This ensures that \e libdvdcss remains free and used only with free - * software. - * - * \section api The libdvdcss API - * - * The complete \e libdvdcss programming interface is documented in the - * dvdcss.h file. - * - * \section env Environment variables - * - * Some environment variables can be used to change the behaviour of - * \e libdvdcss without having to modify the program which uses it. These - * variables are: - * - * \li \b DVDCSS_VERBOSE: sets the verbosity level. - * - \c 0 outputs no messages at all. - * - \c 1 outputs error messages to stderr. - * - \c 2 outputs error messages and debug messages to stderr. - * - * \li \b DVDCSS_METHOD: sets the authentication and decryption method - * that \e libdvdcss will use to read scrambled discs. Can be one - * of \c title, \c key or \c disc. - * - \c key is the default method. \e libdvdcss will use a set of - * calculated player keys to try and get the disc key. This can fail - * if the drive does not recognize any of the player keys. - * - \c disc is a fallback method when \c key has failed. Instead of - * using player keys, \e libdvdcss will crack the disc key using - * a brute force algorithm. This process is CPU intensive and requires - * 64 MB of memory to store temporary data. - * - \c title is the fallback when all other methods have failed. It does - * not rely on a key exchange with the DVD drive, but rather uses a - * crypto attack to guess the title key. On rare cases this may fail - * because there is not enough encrypted data on the disc to perform - * a statistical attack, but in the other hand it is the only way to - * decrypt a DVD stored on a hard disc, or a DVD with the wrong region - * on an RPC2 drive. - * - * \li \b DVDCSS_RAW_DEVICE: specify the raw device to use. Exact usage will - * depend on your operating system, the Linux utility to set up raw devices - * is \c raw(8) for instance. Please note that on most operating systems, - * using a raw device requires highly aligned buffers: Linux requires a - * 2048 bytes alignment (which is the size of a DVD sector). - * - * \li \b DVDCSS_CACHE: specify a directory in which to store title key - * values. This will speed up descrambling of DVDs which are in the - * cache. The DVDCSS_CACHE directory is created if it does not exist, - * and a subdirectory is created named after the DVD's title or - * manufacturing date.
