thats ambigous due to ARGB vs. RGBA
see docs/nut4cc.txt at svn://svn.mplayerhq.hu/nut
for a unambigous variant

should be ok

also feel free to update nut4cc.txt

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
