my attempt at linux-friendly plugin code. cross compiling for win32 should be okay now, just need to add the setting to the buildbot.

#small script to download+install avformat for windows cross compiles.
#linux users are expected to have the library installed locally already. If your version is too old or missing, run the following command to install it (to /usr/local), then delete the gz and directory.
#wget http://ffmpeg.org/releases/ffmpeg-1.2.tar.gz && cd tar xvfz ffmpeg-1.2.tar.gz && cd ffmpeg-1.2/ && ./configure --disable-yasm --enable-shared && make && sudo make install
#we use ffmpeg's version for some reason, as opposed to libav. not sure what the differences are meant to be, but libav seemed to have non-depricated functions defined, docs that say to use them, and these functions missing.
