[MPlayer-users] Re: TV Tuner - howto invert colors?

[Toddmilliner]

Hello again,.

to be honest i am a pretty slack coder.

What i need to do is invert the colors of mplayer when it uses the
tvtuner input

it would bo cool if i could do something like

mplayer -vop invert  ......  I have tried all the other output filters
but none seem to work.

I had a look at the libmpcodecs/vf_*.c code but I really don't have any
idea what is going on.  :(

Here is some code that i have found inverts the colors in the way i
need.  I have no idea how to port this code to mplayer

if anyone could help it would be greatly appreciated

#include <stdio.h>
#include <effecto_machine.h>

static void *negative_effecto (int w, int h, unsigned char *image, void
*private_data)
{
        unsigned char *p = image;
     unsigned int i = w * h * RGB_COMPONENTS;

     while (--i) *p++ = ~(*p);

        return image;
}

this is from a GPL program known as Grabbo

I hope it helps

this code i can understand, the mplayer code is a little beyond me.

anyway if anyone can drop me an email and/or give me some help it would
be greatly appreciated
