That writes the status output to a separate file so you can review it
later. This is useful if it has to run for a long time and you want to
see how far it got if it didn't complete. Just leave it off if you don't

You have to run the mplayer and encoder_example lines in separate
xterms. The idea is that one writes to the fifo, and the other reads
from it. Since they're both running at once you don't need room for the
entire uncompressed video, which saves a lot of disk space. The serial
version looks like:
mplayer -vo yuv4mpeg -o stream.yuv "mf://*.png" -mf type=png:fps=30
(wait while it creates stream.yuv)
encoder_example -o output.ogg stream.yuv

It's a simple example included with the theora source. If you've built
libtheora from source, they'll be in the examples subdirectory. Ubuntu
provides them as part of the 'libtheora-bin' package.
