Custom shaders in MPC?

[PhakeDC]

Hello, I was wondering whether some clever coder out there has mananged to utilise the shader editor in MPC to write new useful shaders (e.g. luminance fix) to use during playback? I searched the web, to no avail. Thanks for any help!

PS - I want shaders to use with "rogue" video formats like RMVB which don't conform to MPC Directshow standards (and thus aren't subjected to external filters like FFDShow or AviSynth.

You mean something like this:

sampler s0 : register(s0);

#define Const_1 (16.0/255.0)
#define Const_2 (255.0/219.0)

float4 main(float2 tex : TEXCOORD0) : COLOR
{
return( ( tex2D( s0, tex ) - Const_1 ) * Const_2 );
}

Thanks, that's nice. Did you code that just for us or do you have a secret stash? What'll it take to bribe you?

Yep it's nice alright.. Care to share more? ;)

I've wrote some filters here : http://www.homecinema-fr.com/forum/viewtopic.php?t=29814317

I'm going to check those out right now, thank you. I find the INVERT filter included in the k-lite pack (or from MPC itself) kinda sucky. I've tried to edit it but I can't seem to make it darker (there is a line that reads something like -1, -1, -1, -1 and if you change those you get diff colors and such)

PS. Is the MPC ini file the best way to add shaders?

by default, MPC store setup ( and shaders ) in registry ... but if you askit, it can use an ini file ...

The "classic" way to add/edit shaders in MPC is to use the Shader Editor ... you can see in real time the result of your change, and you have the result of the shader compiler ... :p

What kind of effect do you want ?

NB: INVERT is include in MPC by default ... whith some others : wave, spotligh, sharpen, invert, contour, deinterlace, emboss, grayscale, letter box ...ect...
