video eq can be implemented at many places:
- codec (see divx4linux, maybe xvid too)
- yuv<->rgb conversion code (vf_scale)
- eq filters (vf_eq, vf_eq2, vf_hue)
- vo driver (think sdl, directfb)
- hardware (think xv, vidix, mga_vid, xgamma)

video eq can be controlled at many ways:
- codec/filter/vo parameters
- -brightness -contrast etc options
- VFCTRL_SET_EQUALIZER control() call (used for 1..8 keys for runtime control)
