you did?

anyway we support ANSI and soon windows way of handing console colors.
We currently do not support java nor curses/termcap/terminfo for handling
colors.

also a dependancy on such things in libavutil is problematic because
they are all many times larger than libavutil itself.

Incandescent light bulbs waste a lot of energy as heat so the EU forbids them.
Their replacement, compact fluorescent lamps, much more expensive, dont fit in
many old lamps, flicker, contain toxic mercury, produce a fraction of the light
that is claimed and in a unnatural spectrum rendering colors different than
in natural light. Ah and we now need to turn the heaters up more in winter to
compensate the lower wasted heat. Who wins? Not the environment, thats for sure
