Dirac is a general-purpose video codec aimed at resolutions from QCIF (176x144) 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.
- Added support for Constant Bit Rate Coding.
- Improved quality of encoded pictures at low bit-rates and for difficult sequences.
- Improved motion vector data partitioning to allow for parallel encoding and decoding of this data especially in hardware.
- Added support for integral motion vector precision.
- Improved Arithmetic coding.
- Solution and Project files for Visual C++ 2005 Express edition.
- Encoder and Decoder API header files have changed so applications using the old API will have to be recompiled.
- Released patches to MPlayer, FFmpeg to comply with this release. Earlier patch to transcode can be used with release.
- DirecShow Filter released to be able to play back Dirac v0.7.0 files in Windows Media Player.
Important Note :
- Directshow Filter for Dirac derived from the Guliverkli's Dirac Splitter. Installation notes are available in INSTALL in the Zip archive. Works with Dirac Version 0.7.0.
