libTheora 1.1 alpha 2 release: next-generation 'Thusnelda' encoder

Xiph.Org is pleased to announce the second alpha release of our next generation encoder for the free Theora video format, codename "Thusnelda". The second release incorporates a number of changes which improve both compression efficiency and execution speed.

This release includes working MSVC project files, but the assembly optimization hasn't yet been ported, so performance there will still be slow. We recommend the xmingw32 build (cross compiled with gcc) if performance on Windows is important.
