It's a standalone package (includes libogg2, optimized Y'CbCr to RGB15 code,
and an ARM optimized Tremor port that Robin Watts also made) and builds
without much effort inside a Maemo development scratchbox. Grab the code
from http://wss.co.uk/pinknoise/theorarm/, mkdir build and run make.
You can test decoding and run benchmarks with the 'testtheora' program that
is built. It won't work for playback--the display code tries to use /dev/fb
(or similar, maybe it was omapfb) which a user can open and write to on the
N900 but will just cause the machine to crash. It probably wouldn't be too
difficult to rewrite the display code to use SDL.
