Detailed Description

Theora encoder using libtheora.

Author:
Paul Richards <paul.richards@gmail.com>
A lot of this is copy / paste from other output codecs in libavcodec or pure guesswork (or both).

I have used t_ prefixes on variables which are libtheora types and o_ prefixes on variables which are libogg types.
