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.
Changes in Dirac 0.8.0:
- Support for interlaced coding
- Added support for full-search block matching.
- Improved constant bit-rate coding mode so that quality crashes and rate explosions are reduced.
- Improved motion estimation
- Added support for larger wavelet-depths in non-MMX mode.
- API changes to conform with spec revision 1.0.0.pre9_02. Application using Dirac libraries will need to be recompiled.
- Released patches to MPlayer, FFmpeg to comply with this release. Earlier patch to transcode can be used with release.
- DirectShow Filter released to be able to play back Dirac v0.8.x files in Windows Media Player
- Minor bug fixes.
