Ok, i am just a little upset since i haven't received any response in other forums about a brightness/contrast issue. The problem is as follows:

When i run a video through mplayer and try to set the brightness, i get this:

"Video attribute 'brightness' is not supported by selected vo & vd."

Same error comes up for hue, or saturation. I tried playing many videos with kaffeine (xine) as well, and they won't let me change any such settings either. I did try other output drivers in mplayer (gl, gl2, etc), and none let me change the settings.

A few things that have changed in my system recently:

1) X.org was installed through debian Sid repo.
2) Video card was upgraded to a Geforce 6600GT Pci-E.

I am using the latest nvidia drivers (1.0-7667), and the Antialiasing/Antistrophic setting are set to "application control".

A google search said to look into the 'xvinfo' output, so here is that:

Like i said, i am not really sure when the trouble started...it could have been when i upgraded to X.org or installed the video card.

I also posted the same problem here:

But no responses, so i really don't know where to turn for help now...its like i haven't even gotten a hint as to what might be wrong.

Thx.

Did you try "-vo X11" ? It *should* work...

I get this after doing that (-vo X11):

-----------------

I'm sorry, There is a small x in "-vo x11"

Try using a video filter like this:

mplayer -vf eq=20:50 your_movie.mpg

the 20:50 is a ratio of brightness to contrast... the default is 100:100 which is saturated... start with 50:50 and adjust the ratio until you have it like you want...

ok, that works but how do i make it so that it will work with kaffeine(xine)/gmplayer? I don't wanna have to run a command everytime, and rather use a gui to change the brightness and such.

I mean, i used to be able to until last week when i upgraded to xorg from xfree.

Thx.

Well, I only use Mplayer from the command line but here is a snippet of my keyboard command file /etc/mplayer/input.conf:

1 contrast -1
2 contrast 1
3 brightness -1
4 brightness 1
5 hue -1
6 hue 1
7 saturation -1
8 saturation 1

Yes, i have those too in my input.conf, but they only work if i use the command that you posted. So, i have to run the command first, then the mapped keyboard keys function. I want it so that i don't have to run the command first or "it just works."

Thx.

The default arguments can be added in your ~/.mplayer/config file

For example, if I want to use "alsa" for audio, then I'll put the line "ao=alsa" (without quotes) in the ~/.mplayer/conf file.

In your case, you might have to use "vf=<something>" I'm not sure what the exact statement would be.

ok, i tried using kplayer, and in its settings, i was able to pass additional paramaters to mplayer, so i just put in ' -vf eq=20:50' and hit apply/ok. That worked! It would be nice to know how to send mplayer the saturation/hue paramaters, but i am happy for now.

Now, the problem is that i use the kaffeine plugin for all the web embedded movies. But kaffeine is based on xine and i have a ~/.xine/config file as well. Anyone know what to change in there so i could get brightness/contrast?

Alright, i messed everything up and completly broke my install (don't ask, i did something really stupid). So i had to reinstall debian sid and xorg using the debian installer. I reinstalled mplayer-386 from the marrilett repo, and tried running it without any paramaters to see what would happen. Well, the brightness, etc work now. However, when i change the brightness in mplayer while its playing a movie, my entire desktop changes the brightness as well. Why is it doing it to the entire desktop? Any way to make it so it does it only to itself?

Sorry you had to re-install... Strange problem, would not think Mplayer could change bright/contrast on the entire DT, unless in fs (full-screen) mode...

Is Mplayer displayed in a window when this happends? Wish I had a answer for you but seems really strange...

Hmm, looks like its back to how it was before...i dunno why it was doing that. Maybe i rebooted
and it fixed itself? Not sure....however, i am back to where i started from:

Video attribute 'contrast' is not supported by selected vo & vd. 0 47%
Video attribute 'brightness' is not supported by selected vo & vd. 47%
Video attribute 'hue' is not supported by selected vo & vd. 1.1% 0 0 47%
Video attribute 'saturation' is not supported by selected vo & vd. 0 48%
