Hi Everyone, OK, I made a trivial hack to pngwriter that dumps 8 bit files. These files are directly convertible by mencoder.
The hack is to go and replace every bit_depth (and bit_depth_) = 16 to bit_depth (and bit_depth_) = 8 Not knowing how libpng works (and that is the purpose of pngwriter - transparency) I don't know what this may break : I'm running on windows and using mingw. I'm using the circle, line and filledtriangle commands from pngwriter and that works fine. I'll post links to some animations, along with what they mean later next week.
