The theora encoding will be done with ffmpeg in future release of mediacoder. I've just updated theroa libraries to build into ffmpeg.

Overview

Since the last update, we've released and seen wide adoption of the new Theora 1.1 'Thusnelda' encoder. The Thusnelda project concentrated on code review, cleanup, and improving efficiency of objectively measurable 'low hanging fruit'.

Encoder improvements continue with the upcoming 1.2 release, 'Ptalarbvorm' [Tall' - ar - vorm] (the P is silent, the b is optional). The Ptalarbvorm release continues with substantial subjective and psychovisual improvements to the encoder. Ptalarbvorm also addresses those aspects of Thusnelda encoding that were objective improvements but did not subjectively improve over the heuristic approaches in 1.0.

Ptalarbvorm is currently in a branch at http://svn.xiph.org/experimental/derf/t ... alarbvorm/.

Upcoming for 1.3 (Eyjafjallajökull ...err... Volcano)
Multithreading

At the moment, the main feature mentioned as landing post 1.2 is encoder multithreading.
