That's me; I'm usually on IRC too

For ARM7 there aren't really any special optimizations beyond adding  
the appropriate -mcpu to your cflags, so you'll have to configure x264  
with --disable-asm.

For libx264 usage documentation, x264.h is pretty much it. The x264  
commandline is more than just an example program, but you could use it  
as a reference in using libx264 or simply use it via pipes, depending  
on what you need to do.
