2001-11-29 19:03  hh

	* dvdread/: bswap.h, dvd_reader.c, dvd_reader.h, dvd_udf.c,
	dvd_udf.h, ifo_print.h, ifo_read.h, ifo_types.h, nav_print.h,

2001-11-28 20:16  hh

	* dvdread/: ifo_print.c, ifo_read.c: Handle mastering error on
	Enemy of the State region 2 (de).

2001-10-15 20:16  hh

	* NEWS, configure.in, dvdread/bswap.h, dvdread/dvd_reader.c,
	dvdread/ifo_read.c: Bump version to 0.9.2 for release (2001-10-11).
	 Add support for BSD/OS. Make sure that the raw device is used on
	all BSD variants for the CSS ioctls to work correctly.	Small bug
	fix for access to mounted DVD via soft-links and a malloc/free
	mistake.  Increase an assert level for pgcn numbers in the part of
	title list.

2001-09-28 20:25  hh

	* dvdread/ifo_read.c: Allow Titles with 0 PTTs.  Allow a ptt_srpt
	with an empty title.  Allow empty Cell Address tables.	Allow an
	empty VOBU Address Map. This is to get "Magic Knight Rayearth:
	Daybreak" to work, it might be master wrong.  Hard to se how a VTS
	without any PGCs, Cells or VOBUs can be correct.

2001-09-28 20:11  hh

	* dvdread/: bswap.h, dvd_reader.c: Add NetBSD support.	Change the
	code to use /dev/rcd* rather than /dev/cd* for all *BSD, this is
	apparently needed to use the CSS ioctls.  Extend bswap with NetBSD
	header.

2001-09-18 03:53  hh

	* dvdread/Makefile.am, dvdread/bswap.h, dvdread/dvd_reader.c,
	dvdread/ifo_read.c, NEWS, configure.in: Change the way the endian
	swaps are defined and make sure Solaris x86 works.  Fix from
	Juergen Keil for a bug that caused libdvdread to close random fds. 
	Update the limit on the number of pgcs in the pgcit to 10000.
	Correct bug in 0.9.0 that made using a DVD located on a normal
	filsystem impossible.  Bump the version in confgure.in to 0.9.1 and
	the library revision number for the release.

2001-09-18 02:36  hh

	* Makefile.am, NEWS, configure.in, dvdread/Makefile.am,
	dvdread/dvd_reader.c, dvdread/dvd_reader.h, dvdread/dvdcss.h,
	dvdread/ifo_read.c, src/play_title.c: Include the bootstrap script
	in the dist.  Change the package name to libdvdread (was dvdread). 
	Use stat64 so that using an image file of a DVD should work. 
	Change some more types in the interface to use int rather than
	int32_t, also some internal changes of types.  Make it crack the
	keys for all titles when opening the first as to not pause later
	during playback.  Make sure to use the raw device name for access
	under Solaris as using the CSS calls does not work on the block
	device.  Make sure to get an absolute path for the directory name
	used to search the mount table with.  Update/correct some error
	messages.  This is what was released as libdvdread-0.9.0.

2001-09-02 23:45  hh

	* dvdread/Makefile.am, dvdread/dvd_udf.c, dvdread/dvd_udf.h,
	src/play_title.c: Add some header files to the dependencies of
	libdvdread so that they are included in the dist. Change the types
	of UDFFindFile.  Update the partiotion handling in the UDF code. 
	Correct play_title for the new incterface (expect blocks not bytes
	read).

2001-08-28 21:40  hh

	* dvdread/ifo_read.c: Do not assume a pgci_ut has been
	read/allocated. Check ponter before dereferring it to free
	sub-componets.

2001-08-28 21:34  hh

	* dvdread/dvd_udf.c: Handle files with length 0. It faild and
	reported the location and size of the director that a file was
	located in if it didn't have any block allocated for it content.

2001-08-27 02:13  vektor

	* dvdread/: dvd_reader.c, dvd_reader.h:  - Added a GetFileSize
	style call.
	 - Made the close calls a bit more robust.
	 - Removed an annoying printf.

2001-08-22 23:59  hh

	dvdread/dvd_reader.h, dvdread/dvd_udf.c, dvdread/ifo_print.c,
	dvdread/ifo_read.c, dvdread/nav_print.c, dvdread/nav_read.c,
	dvdread/nav_read.h, src/play_title.c: Some API changes, sorry for
	this, but now the interface nolonger has any reference to off64_t. 
	Remove unused length parameter to the nav functions.  Return blocks
	read rather than bytes read for the DVDReadBlocks function.  Added
	switch to enable lots of gcc waring flags. Correct lots of warnings
	discoverd by the new flags.

2001-08-18 01:22  hh

	* README, configure.in, dvdread/dvd_reader.c, dvdread/dvd_reader.h:
	Change _all_ occurrences of libcss to libdvdcss this time.

2001-08-02 02:09  hh

	* dvdread/dvdcss.h: Add the libdvdcss's header file so we compile
	without it beeing installed.

2001-08-02 02:05  hh

	* TODO, configure.in, dvdread/Makefile.am, dvdread/bswap.h,
	dvdread/dvd_reader.c, dvdread/dvd_reader.h, dvdread/dvd_udf.c,
	dvdread/dvd_udf.h, dvdread/ifo_print.c, dvdread/ifo_read.c,
	src/Makefile.am: Changed to use libdvdcss (from the VideoLAN guys)
	by vektor.  FreeBSD fixes from Marc van Woerkom and OpenBSD fixes
	from Bj鰎n Sandell.  Small configure fixes to work better on *BSD
	and other systems.  Fix src/Makefile.am thinko/typo.  Convert
	dvd_udf to use uint[8|16|32]_t types.

	src/title_info.c: libdvdread provides a simple foundation for
	reading DVD-Video discs and images.
	
	It offers DVD applications:
	
	1. A simple abstraction for reading the files on a DVD	 
	(dvd_reader.h).  2. A simple library for parsing the information
	(IFO) files    (ifo_read.h/ifo_types.h).  3. A simple library for
	parsing the navigation (NAV) packets	(nav_read.h/nav_types.h).
