项目描述

Schrödinger is an implementation of the Dirac video codec, a modern wavelet-based video codec. It features both an encoder and a decoder and GStreamer plugins. Mappings have also been developed for putting Dirac into both the Ogg container format and the MPEG Transport stream container format.

1.0.7

编码器默认改为稳定的质量，质量= 5.0。几个编码和解码错误固定在GStreamer的元素和基类。开始/停止工作线程是固定的。最近线程变化移植到所有后端。在序列头无效的清洁区，现在消毒。保护增加了对一些意想不到的图片向后跳过。在奥斯悬空领域将被丢弃。此外，还有各种其他修补程序。
The encoder default was changed to constant quality, quality=5.0. Several encoding and decoding bugs were fixed in the GStreamer elements and base classes. Starting/stopping of worker threads was fixed. Recent threading changes were ported to all backends. Invalid clean areas in the sequence header are now sanitized. Protection was added against unexpected backwards skips of the picture number. Dangling fields at EOS are discarded. There were also various other fixes.

1.0.3

编码器速度已经提高3倍，图像质量的编码器生产也得到了改进。
标签: Major feature enhancements
The encoder speed has been increased 3x, and the image quality produced by the encoder has also been improved.

1.0

这是第一次ABI的稳定和100％的比特流规范的版本。
标签: Major bugfixes
This is the first ABI stable and 100% bitstream specification compliant version.

0.9.0

此版本是同步大部分是最新的狄拉克规范版本。编码参数的默认值也得到了改善，使一个更好的结果时，转换文件格式。大量的工作已经完成，以便到指定的编码比特率。请注意，狄拉克流规格仍在调整，所以这个版本中创建的文件没有可能与这一事件和其他狄拉克解码器的未来版本。
标签: Major feature enhancements
This release is mostly in sync with latest version of the Dirac specification. The encoding parameter defaults have also been improved to give a much better result when transcoding files. A lot of work has been done to allow encoding to a specified bitrate. Be aware that the Dirac bitstream specification is still being revised, so the files created with this version are not likely to work with future versions of this and other Dirac decoders.

0.6.0

这是第一个版本，应该完全与狄拉克流规范。随着包括GStreamer的插件用户应该可以较容易地进行编码和解码狄拉克媒体。
标签: Major feature enhancements
This is the first release that should be fully compliant with the Dirac bitstream specification. With the included GStreamer plugins users should be easily able to encode and decode Dirac media.
