12 * Update for libdvdcss documentation.
13 * Reworked Keith Packard's raw device patch. The name of the raw device
14 is in the environment variable DVDCSS_RAW_DEVICE.
15 * Fixed a bug in libdvdcss: the key wasn't searched when it had to.

20 * Got rid of DVDCSS_SEEK_INI.
21 * Removed the i_flags argument to dvdcss_open. Everything is done through
22 environment variables now.
23 * Fixed a buffer overflow in CSSAuth().
24 * libdvdcss port to OpenBSD.
25 * Fixed NetBSD (and probably OpenBSD) libdvdcss compilation.
26 * Fixed undefined KEY_SIZE compile bug mentioned by Dave Thorup.
27 * Fixed CSS ioctl for Darwin/OSX - still might need tweaking of 'dataLength'
29 * Added ReadTitleKey ioctl for Darwin/OSX.
30 * When using title cracking method in libdvdcss, the key is only checked at
31 title start, not before each chapter.
32 * Use of an environment variable to choose libdvdcss method.
33 * New features for libdvdcss: we have three ways now to decode a title key.
34 * 1) Crack the title key (the method that was here before). The only change
35 here is that we search the key for the exact chapter we are seeking with
36 DVDSetArea (in case the key has changed within a title). It is maybe not a
38 * 2) Crack the disc key, which allows us to decode instantly all title keys.
39 I've used an algorithm from Frank Stevenson ; it eats much memory (64MB),
40 and takes about 15 s at launch time.
41 * 3) Decode the disc key with player keys (libcss method). However, you need
42 licensed player keys at build time for this to work.
43 * Darwin ioctl, courtesy of ej0.
44 * If we see 3000 unencrypted blocks assume that the title is unencrypted.
45 * If we have not seen any encrypted block and then discover that the block
46 just read is not a valid block of an MPEG2 Program stream, assume that the
48 * Empty keys (for unscrambled sectors) are now cached as well.
49 * We try to decrypt the file even if DVD ioctls are not available.

54 * Added BSD/OS libdvd by Steven M. Schultz <sms@TO.GD-ES.COM> in
55 extras/BSDI_dvdioctl after he suggested us to do so. License is GPL.
56 * ./configure now checks for an installed libdvd under BSD/OS and
57 falls back to ours if not found.
58 * Fixed harmless typos in yesterday's Solaris libdvd patches.
59 * Bumped libdvdcss version number up to 0.0.3.
60 * Solaris DVD decryption support by HÃ¥kan Hjort <d95hjort@dtek.chalmers.se>.
61 * BSD/OS 4.3beta1 fixes by Steven M. Schultz <sms@TO.GD-ES.COM>.
62 * libdvdcss* packages are now a bit more policy-compliant.
63 * Fixed a Win32 bug in libdvdcss. This bug was appearing on title change.
66 Wed, 22 Aug 2001 15:18:01 +0200
68 * Fix in libdvdcss in the key caching code.
69 * Changed libdvdcss API to force binary incompatibility. Yeah, this is
70 evil, but if we don't do it now we'll have to do it when more people
72 * Fixed minor libdvdcss stuff such as the soname and compilation flags.
73 * dvdcss_readv() optimisations for Win32.
74 * Fixed _win32_dvdcss_aread() to work around the WinASPI32 64kb transfer
76 * libdvdcss segfault fixes.
77 * Fixed 2 Win32 bugs in libdvdcss (in _win32_dvdcss_readv), one of them
78 should have prevented the Win9x dvd input from working.
79 * Moved the "if(Win2k)" out of the loop in _win32_dvdcss_readv.
80 * libdvdcss enhancements by Billy Biggs <vektor@dumbterm.net>. This breaks
81 vlc's DVD input (looks like decoders are expecting data too early and
82 DVD input can't cope with it due to decryption). Needs to be investigated.
83 * Removed unnecessary translations in the win32 code from block offsets to
84 byte offsets. This was overflowing some variables.
85 * Reduced the complexity of the Win9x ASPI functions because we only need
86 to handle DVD drive access.
87 * Win32 code now handles seeking in areas above 2.1 Go on DVDs.
88 * Additional MacOS X DVD ioctl work by Eugenio Jarosiewicz
92 Tue, 19 Jun 2001 08:53:16 +0200
94 * First libdvdcss version (0.0.1).
95 * Fully working Windows DVD ioctl support by Jon Lech Johansen.
96 * Merged dvdcss_init and dvdcss_open into dvdcss_open, and dvdcss_close
97 and dvdcss_end into dvdcss_close. libdvdcss API now has 7 functions.
98 * Exported the CSS part of the dvd plugin into a library.
