[MPlayer-dev-eng] [PATCH] vf_eq2 extensions

[Hampa Hug]

Hello

(I sent this message a few hours ago using a wrong email address.
Hope it doesn't show up twice)

I've been working a bit on the eq2 filter. I intended to test this
a little more, but since the issue came up in another thread here
I decided to post what I have so far

- Brightness / contrast / gamma adjustment is unchanged
- Saturation adjustment is new. It uses two LUT's for the U and
  V channel
- Hue adjustement is new as well. This is implemented as a simple
  rotation in U-V space.

The filter does these three types of adjustments independantly
and only if necessary.

The patch is pretty big as this is basically a rewrite of the
entire filter.

Daniel: I think it should be possible to combine vf_eq2 and your
gamma patch into a single filter. This would then be a pretty
complete equalizer.

cheers
Hampa
