Default Why no xv_brightness etc?

Why isn't xv_brightness, xv_contrast etc not supported in the drivers? Do I really need to change the settings for the whole screen with xgamma or nvidia-settings when watching videos with xine or mplayer? Or should I use another driver for video instead of xv? (The one's I've tested seem slow or not working at all)

NVIDIA drivers 1.0-6106 & Fedora Core 2.

I have the same problem only when I am using twinview.

This is one of the reasons I prefer using Xinerama intead of twinview.

In case of twinview it is quite normal that you can't adjust Xv settings. In short the problem is that the videocard only has one video overlay which can only be used for one output, so because of that the drivers default to blitting. For plain blitting Xv doesn't do anything, normal gamma settings help in that case. In recent drivers it might be possible again as the 3d part is now used to do the overlay work (on recent cards).

Also note that old tnt/tnt2 are limited in Xv control options.

I forgot to tell that I use Twinview and my card is a GF4 Ti 4200. So it's possible to use Xinerama instead of Twinview and the xv_brightness would work?

I think so. But you only get OpenGL on the first screen. Which is not that bad, since many OpenGL apps (including games) behave rather erratic in twinview.

And this way I can use the "1", "2", "3", "4" keys to set Brightness and Contrast in MPlayer.

PS: I have attached my xorg.conf (a.k.a. XF86Config) if you were wondering on how to get Xinerama working.
