I think libvisual should handle this. Many X11 installations also
have 32 bit BGR XImages by default. This colorspace thing will
show up everywhere.

gavl does runtime autodetection, and on non mmx platforms, it won't try to
compile the mmx stuff at all. The accelleration modi can be selected
using individual flags (like in libvisual) or with
simple speed<->quality sliders.

In principle, gavl can also support (slow) high quality conversions.
Up to now, I could not find any visible errors due to the lack of
interpolating, so I didn't write them yet.
