libtheora 1.0rc1
- Merge x86 assembly for forward DCT from Thusnelda branch.
- Update 32 bit MMX with loop filter fix.
- Check for an uninitialized state before dereferencing in propagating
decode calls.
- Remove all TH_DEBUG statements.
- Rename the bitpacker source files imported from libogg to avoid
confusing simple build systems using both libraries.
- Add VS2008 project files.
- Add explicit casts as a work-around for Solaris's cc ignoring the
signedness of bitfield types.
- Set quantization parameters to default values when an empty buffer is
passed with TH_ENCCTL_SET_QUANT_PARAMS.
- Split encoder and decoder tests depending on configure settings.
- Return lstylex.sty to the distribution.
- Disable inline assembly on gcc versions prior to 3.1.
- Remove extern references for OC_*_QUANT_MIN.
- Make various data tables static const so they can be read-only.
- cpuid assembly fix for MSVC.
- Remove ENCCTL codes from the old encoder API.
- Implement TH_ENCCTL_SET_KEYFRAME_FREQUENCY_FORCE ctl.

libtheora 1.0beta3 (2008 April 16)
- Build new libtheoradec and libtheoraenc libraries
supporting the new API from theora-exp. This API should
not be considered stable yet.
- Change granule_frame() to return an index as documented.
This is a change of behaviour from 1.0beta1.
- Document that granule_time() returns the end of the
presentation interval.
- Use a custom copy of the libogg bitpacker in the decoder
to avoid function call overhead.
- MMX code improved and ported to MSVC.
- Fix a problem with the MMX code on SELinux
- Fix a problem with decoder quantizer initialization.
- Fix a page queue problem with png2theora.
- Improved robustness.
- Updated VS2005 project files.
- Dropped build support for Microsoft VS2003.
- Dropped build support for the unreleased libogg2.
- Added the specification to the autotools build.
- Specification corrections.

libtheora 1.0beta2 (2007 October 12)
- Fix a crash bug on char-is-unsigned architectures (PowerPC)
- Fix a buffer sizing issue that caused rare encoder crashes
- Fix a buffer alignment issue
- Build fixes for MingW32, MSVC
- Improved format documentation.
libtheora 1.0beta1 (2007 September 22)
- Granulepos scheme modified to match other codecs. This bumps
the bitstream revision to 3.2.1. Bitstreams marked 3.2.0 are
handled correctly by this decoder. Older decoders will show
a one frame sync error in the less noticable direction.
It also includes the changes done for alpha8, which was short lived and
is only interesting for historical reasons:
libtheora 1.0alpha8 (2007 September 18)
- Switch to new spec compliant decoder from theora-exp branch.
Written by Dr. Timothy Terriberry.
- Add support to the encoder for using quantization settings
provided by the application.
- more assembly optimizations
|

changes:
- Enable mmx assembly by default
- Other build fixes
- time testing mode (-f) for the dump_video example

libtheora 1.0alph6 (2006 May 30)
* Merge theora-mmx simd acceleration (x86_32 and x86_64)
* Major RTP payload specification update
* Minor format specification updates
* Fix some spurious calls to free() instead of _ogg_free()
* Fix invalid array indexing in PixelLineSearch()
* Improve robustness against invalid input
* General warning cleanup
* The offset_y member now means what every application thought it meant
(offset from the top). This will mean some old files (those with a
non-centered image created with a buggy encoder) will display differently.

[ 2005 August 20 - libtheora 1.0 alpha 5 release ]
We're pleased to announce a new release of the libtheora reference
implemenation. This is an incremental update over alpha 4, to draw
a line under recent work before we start adding optimization work.
There are two important bugfixes as well, so we recommend upgrading
to everyone. This release is source and binary compatible with 1.0
alpha 4.

Changes since the alpha3 release:
* first draft of the Theora I Format Specification
* API documentation generated from theora.h with Doxygen
* fix a double-update bug in the motion analysis
* apply the loop filter before filling motion vector border in the reference frame
* new utility functions: theora_packet_isheader(), theora_packet_iskeyframe(), and
theora_granule_frame()
* optional support for building without floating point
* optional support for building without encode support
* various build and packaging fixes
* pkg-config support
* SymbianOS build support

All library names listed by *.la files no longer need to be listed
in the PLIST, e.g., instead of:
lib/libfoo.a
lib/libfoo.la
lib/libfoo.so
lib/libfoo.so.0
lib/libfoo.so.0.1
one simply needs:
lib/libfoo.la
and bsd.pkg.mk will automatically ensure that the additional library
names are listed in the installed package +CONTENTS file.
Also make LIBTOOLIZE_PLIST default to "yes".

Theora is Xiph.Org's first publicly released video codec, intended for
use within the Ogg's project's Ogg multimedia streaming system. Theora
is derived directly from On2's VP3 codec; currently the two are nearly
identical, varying only in encapsulating decoder tables in the bitstream
headers, but Theora will make use of this extra freedom in the future to
improve over what is possible with VP3.
