libTheora 1.1 alpha 1 release: next-generation 'Thusnelda' encoder
Xiph.Org is pleased to announce the first alpha release of the rewrite of the Xiph.Org reference encoder for the Theora video format, codename "Thusnelda".
Please download, test and give us feedback!
This is an alpha release consisting of substantially new code, and so may be unstable. We're making it more widely available at this point to facilitate wider testing and flush out unknown issues. The primary change is a completely rewritten encoder with vastly improved quality vs. bitrate in the default VBR/constant-quality mode, and better tracking of the target bitrate in CBR/ABR modes. There are some minor changes to the decoder and examples, but the new encoder is the reason to try out this release.
As this is an alpha release intended to get new code into the hands of testers as quickly as possible, it is shipping with a few known caveats that are being fixed:
- GNU autotools and scons builds should work on GNU/Linux/BSD systems, including MacOS X
- The Apple xcode project should work, but doesn't build a separate libtheoraenc. Use the legacy libtheora build for now.
- The xmingw32 build only mostly works.
- MSVC project files need updating for source code rearrangement.
- Some minor build fixes haven't been ported from the 1.0 release yet.
Development work for this is still on a separate branch, and will remain so until we have some of the build and code reorganization issues settled. If you're curious to track the ongoing development, please 'svn checkout http://svn.xiph.org/branches/theora-thusnelda/'.
Thanks, and happy hacking!
