[gentoo-user] Adjusting brightness on videos. kmplayer in particular.

[Dale]

Hi,

I downloaded CSI and a NCIS video a while ago.  I'm trying to watch it
but it is really dark.  I am using kmplayer with mplayer for the
backend.  I found where it says you can adjust brightness and contrast
but they don't do anything.  The screen looks fine outside of watching a
show.  Here is some emerge info just in case I missed a USE flag or
something:

I also checked the monitor itself and the brightness is all the way up
to the max.  This is a older system but I have a Nvidia FX-5200 video
card which generally works fine for me.  Am I missing something?

Thanks.

Have you tried changing the gamma?

I tried changing all the things in the menu that pops up.  None of them
do anything at all.  They move and they are not grayed out or anything,
they just don't work.  It reminds me of adjusting the volume when it is
muted. 

Ideas?

Try other output drivers. Run "mplayer -vo help" to see what drivers
are supported. I've just tried it with xv (default) and it didn't work.
x11 driver works, but the brightness of the whole X changes. Using gl
and gl2 output everything works as expected.

You da man !!  I first checked out the command you gave and I have a lot
of options listed.  After reading the man page, should I mention that
thing is HUGE, I then opened kmplayer and checked out the options
there.  I selected the OpenGL driver and it now works.  It goes from
completely black to blindingly white. 

Now I can watch my shows and see something besides the light bulbs.  O_O

THANKS MUCH !!

You can adjust contrast, hue, and saturation as well. Changing the hue
doesn't work here anymore for some reason, though.

I didn't check the hue but the others worked like they should.  I'll try
those in a bit.  I have to make a grocery run for a friend.

Same here.  The others work but not the hue part.  Not sure what it does
but I couldn't see any difference when I changed it.  Isn't that like a
red/green balance thing?

Quite off-topic but:
