hi there !
I got a little problem, I’m trying to control contrast and brightness (and maybe also saturation) on a video stream coming from the VideoIn node but I didn’t manage to do it propoerly.
In fact I tried to do it with the VideoTexture Node (the one with additional options , It works, but not as was expected.
Here is a little schema of my patch :
VideoIN
|
|
|
ColorTracker
|
|
|
Contour
|
|
|
VideoTexture (and Renderer)
And so, I would like to add more contrast and brightness to the videostream from VideoIN before Colortracker work on it (to clean the tracking in fact) but (logically) when I modify contrast on videoTexture, It don’t change anything on the tracking ( because VideoTexture is at the end of the chain I think)
So I would like to know how I can modify videostream’s contrast and brightness before colortracking ? (Maybe with some shaders, but I’m not familiar with pixelshaders, so I don’t know where to look at)
So If anyone has an idea, it would be very nice to tell me about it ^^
