Dirac is a prototype video codec, under development by BBC R&D, and initially
released in March 2003.
Dirac is a general-purpose video codec aimed at resolutions from QCIF
(180x144) to HDTV (1920x1080) progressive or interlaced. It uses wavelets,
motion compensation and arithmetic coding and aims to be competitive with
other state of the art codecs.

changes:
This release is a major update on xine-ui.
It comes with a big cleanup of the user interface, including an improved context
menu, and lots of details of the included "xitk" toolkit.
Additionally, this release fixes some security issues (referenced in XSA-2004-2).
Therefore, we recommend you to upgrade as soon as possible, especially if you are
using xine to play URLs/MRLs you obtained from
also fix some pthread_mutex abuse, and use GNU readline for xine-remote
changes:
This release improves playback of some streams, reduces flickering
of OSD and brings a whole bunch of updated libraries.
It does also fix a vulnerability in xine's RTSP streaming code.
See XSA-2004-3 for more information!
XXX powerpc asm stuff needs to be checked
XXX didn't test the "arts" stuff
-properly libtoolize some libraries to get dynamically loadable modules,
use a hack from SDL to make libtool work with nasm (thanks wiz for
the hint)
-run aclocal and autoconf, otherwise the autoconf version skew scews
things up
XXX we shouldn't use autoconf et al for the build but commit
patches to configure and Makefile.in
-make sure we don't get trapped by the X11R6 freetype2 nonsense
This tool creates XviD configuration files. The generated configuration
file is meant to be read by transcode's xvid4 export module. This module
(and the configuration file) is intended to be used with XviD 1.0
(dev-api-4).
Submitted to pkgsrc-bugs by bsd4ever@nospam.lan with some minor
cleanup by me.
Changes:
- explicitly disable wxWindows support
- mark it as using c++
- prepare for mmg import
- delint
0.8.9:
======
- mmg: new feature: mmg will ask for confirmation before overwriting
a file. This can be turned off on the settings tab.
- mmg: new feature: Implement drag'n'drop of files onto the input,
attachment and chapter tabs. For the input and attachment tabs
it works like pressing the 'add' button. On the chapters tab it
works like calling 'Chapter Editor -> Open'.
- mkvinfo/mmg: Enabled compilation with wxWidgets 2.5 and Unicode
enabled builds of wxWidgets.
- all: Increased the precision for timecodes in chapter files to
nanoseconds (optionally, you can still use fewer digits after
the '.').
- mkvmerge: Fixes for compilation with gcc 3.4.
- mkvmerge: bug fix: Some strings read from RealMedia files were not
zero-terminated resulting in broken track recognition for some
files.
gst-plugins-* packages. Generating a description during installation
is not well supported and causes problems when creating the README
files, for example.
Changes:
0.8.8:
======
- mkvtoolnix now depends on libebml 0.7.0 and libmatroska 0.7.0.
- mkvinfo: bug fix: mkvinfo was forcing libmatroska not to handle
unknown elements and crashed on those.
- mmg: new feature: When adding Matroska files the video track's
display dimensions are displayed as well.
- mmg: bug fix: On non-Windows systems some combinations of wxWindows
and GTK caused continuous 100% CPU usage after a special call
to wxExecute.
- mkvmerge: new feature: Implemented reading AAC from AVIs.
- mkvmerge: bug fix: The Flac packetizer was accessing uninitialized
memory resulting in a crash on Windows.
- mkvemrge: bug fix: Fixed the handling of RealMedia files with 'multirate'
tracks (again).
- mkvmerge: bug fix: On some rare occasions chapters were not written
correctly when splitting was active.
- avilib: bug fix: Fixed compilation on big endian systems.
0.8.7:
======
- mkvinfo: new feature: Added a terse output format via '-s'.
- mkvmerge: new feature: If using MPEG4 video and no aspect ratio or display
dimensions are given mkvmerge will extract the aspect ratio
information from the stream and automatically set the display
dimensions accordingly.
- mkvmerge: bug fix: Using audio sync on AC3 tracks read from Matroska files
did not work.
- mkvextract: new feature: Added extraction of RealAudio and RealVideo tracks
to RealMedia files.
- mmg: new feature: Added a 'job queue'. The current settings can be added as
a new job, and all pending jobs can be started for batch processing
without user interaction.
Changes:
- Switch to LGPL license
- Update the copyright years
- Fix minor things in test examples
- Fix a problem when MATROSKA_VERSION is set to 2

- No more new elements for sample accurate seeking
- Added code that allows libmatroska to be built as a DLL on Windows.
- Updated the MinGW build system.
- No more StdInclude
- Add support for SampleScale and BlockSamples
