adjust brightness and contrast

[GoogleCodeExporter]

Is it possible to adjust the brightness and contrast, either from the menu
or from a config file? I am finding all my ripped copies of Star Trek DS9
and Voyager are very dark, and I have to turn the brightness of the TV to max.

I used to use geexbox alot and used the keyboard for this adjustment. It
would round out what is a really good package!

Thanks for the great development!

MPlayer has the following parameters:

−brightness <−100−100>
Adjust the brightness of the video signal (default: 0). Not supported by all 
video
output drivers.

−contrast <−100−100>
Adjust the contrast of the video signal (default: 0). Not supported by all video
output drivers.

So you can either add fixed settings to your mplayer.conf, add keys to adjust 
these
settings in input.conf or add them as variable preferences to change in 
menu.conf.

What would the specific procedure be if I wanted to replace the volume buttons 
on the 
controller with brightness in increments of 1? I'm not very proficient at this 
kind of 
thing. Thanks!

I am also interested in how to adjust the brightness and/or contrast.  I've 
tried
adding "brightness=50" to mplayer.conf and it doesn't seem to do anything.  
Please help!

Okay this problem has been plaguing me for months now and I finally found the
solution. I am using my Wii on a CRT TV and I think that it may not be a 
problem on
LCD or better televisions. This is known as a Video Filter in Mplayer.

I edited my Mplayer config file by coping this piece of code into it:

# Write your default config options here!
# eq[=brightness:contrast] (OBSOLETE)
# default:0:0
#
# eq2[=gamma:contrast:brightness:saturation:rg:gg:bg:weight]
# default:1.0:1.0:0.0:1.0:1.0:1.0:1.0:1.0
#
# hue[=hue:saturation]
# default:0.0:1.0
vf=hue=0.0:1.0,eq2=1.0:1.0:0.1:1.0:1.0:1.0:1.0:1.0

I have also uploaded a copy of my mplayer.conf if you just want to copy it into 
the
\apps\mplayer_ce\ folder.

I tried editing my input.conf file so I could adjust the brightness and 
contrast but it did not work. I replaced

RIGHT seek +30
LEFT seek -30
DOWN seek -300
UP seek +300

with 

RIGHT contrast 1
LEFT contrast -1
DOWN brightness -1
UP brightness 1

and it did not work. Now the buttons don't do anything at all. Is this the 
proper way to edit the button config? If not, how do I do it?

works perfectly. Thanks!
