This sounds like a great project.  Maybe it would be helpful for you to
look at the existing Verilog/FPGA implementation of a Theora encoder:

http://sourceforge.net/projects/elphel/files/elphel333/6.3.9/elphel_6.3.9.tar.gz/download

http://www3.elphel.com/linuxtag/talks_2005/paper-11081

This encoder from Elphel only implements a very small subset of Theora
(for example, it does not use motion vectors), so it is not very useful.
You may be able to save some time by reusing some of its code while
producing a more advanced encoder.
