Detailed Description

Theora encoder using libtheora.

Paul Richards paul..nosp@m.rich.nosp@m.ards@.nosp@m.gmai.nosp@m.l.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.
