Independent Adjustment of Brightness in BTTV inputs
Description of Patch
Hack to allow you make independent adjustments of the brightness, contrast, saturation and hue of each inputs of a BTTV board, single chip.
This is useful for accessing cams of different manufacturers or in different environments.
Still it has bugs to be solve: when we make adjust the contrast (or brightness, or saturation, or hue) for 0 and after that we make the same in another input occurs the interference in the adjustment of the first one.
Modifications only in the archive video.c (video_freebsd.c not yet)…
