libtheora 1.1 incorporates a substantially improved encoder, codenamed 'Thusnelda'. Compared to libtheora 1.0, the new encoder can produce comparable quality encodings at a lower bitrate, or better quality at the same bitrate.
Over the last year, Mony has produced a series of detailed reports describing the Thusnelda improvements as they have been developed: http://web.mit.edu/xiphmont/Public/theora/demo2.html http://web.mit.edu/xiphmont/Public/theora/demo3.html http://web.mit.edu/xiphmont/Public/theora/demo4.html http://web.mit.edu/xiphmont/Public/theora/demo5.html http://web.mit.edu/xiphmont/Public/theora/demo6.html http://web.mit.edu/xiphmont/Public/theora/demo7.html
Benefit to Fedora
A lot of positive momentum has been building around open video on the web. With this feature, Fedora becomes more attractive as a platform for producing video content in open formats.
libtheora needs to be updated. All video-encoding applications that support theora will transparently benefit from the improvements in Thusnelda.
How To Test
Use a video-encoding application to produce theora-encoded content. Compare the quality with content produced with libtheora 1.0 and notice the improved quality.
Revert to libtheora 1.0.
No specific documentation should be needed, libtheora 1.1 is a transparent replacement for libtheora 1.0.
Fedora 11 comes with libtheora 1.1, including the new 'thusnelda' encoder.
