You complain at 1 bpp data being converted to another pixel format when 
doing just "ffmpeg -i in.avi -c:v rawvideo out.avi". But you won't get 
any 2 bpp or 4 bpp video in the output file either. It will be 8 bpp 
(albeit without a palette, for some inexplicable reason). But that seems 
perfectly OK...
