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
and add a new helper target and script, "show-buildlink3", that outputs
a listing of the buildlink3.mk files included as well as the depth at
which they are included.
For example, "make show-buildlink3" in fonts/Xft2 displays:
zlib
fontconfig
iconv
zlib
freetype2
expat
freetype2
Xrender
renderproto
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.
RECOMMENDED is removed. It becomes ABI_DEPENDS.
BUILDLINK_RECOMMENDED.foo becomes BUILDLINK_ABI_DEPENDS.foo.
BUILDLINK_DEPENDS.foo becomes BUILDLINK_API_DEPENDS.foo.
BUILDLINK_DEPENDS does not change.
IGNORE_RECOMMENDED (which defaulted to "no") becomes USE_ABI_DEPENDS
which defaults to "yes".
Added to obsolete.mk checking for IGNORE_RECOMMENDED.
I did not manually go through and fix any aesthetic tab/spacing issues.
I have tested the above patch on DragonFly building and packaging
subversion and pkglint and their many dependencies.
I have also tested USE_ABI_DEPENDS=no on my NetBSD workstation (where I
have used IGNORE_RECOMMENDED for a long time). I have been an active user
of IGNORE_RECOMMENDED since it was available.
As suggested, I removed the documentation sentences suggesting bumping for
"security" issues.
As discussed on tech-pkg.
I will commit to revbump, pkglint, pkg_install, createbuildlink separately.
Note that if you use wip, it will fail! I will commit to pkgsrc-wip
later (within day).
developer is officially maintaining the package.
The rationale for changing this from "tech-pkg" to "pkgsrc-users" is
that it implies that any user can try to maintain the package (by
submitting patches to the mailing list). Since the folks most likely
to care about the package are the folks that want to use it or are
already using it, this would leverage the energy of users who aren't
developers.
[ 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
in the process. (More information on tech-pkg.)
Bump PKGREVISION and BUILDLINK_DEPENDS of all packages using libtool and
installing .la files.
Bump PKGREVISION (only) of all packages depending directly on the above
via a buildlink3 include.
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.
