mplayer can't adjust brightness


I'm using mplayer to view videos. When I try to change the brightness, I get a message: Video attribute 'brightness' is not supported by selected vo & vd. 0 0%

I have a Riva TNT2 Nvidia graphics card

This happened after I upgraded to slackware 10. I have edited the xorg.conf file to use "nv" driver.

When I use xgamma to change the brightness, it works. I have also downloaded the Nvidia drivers from their website. But when I use that driver, I can only change the brightness of the desktop, the video remains unaffected.

So, my question is:
How can I change the brightness in mplayer itself (not using xgamma but using the "3 & 4" keys)

I believe this is a feature of particular video-output drivers from within mplayer. If you go to Preferences, Video, within mplayer (from gmplayer, right-click on the video window) and choose a different video-out driver, it should work. I use "XV" with no problems.

I took me a while to get gmplayer up and running. (I just had mplayer earlier). I went to preferences and Video as u said. These are the options that I have :

1) XV
2) X11
3) gl2
4) xvidix

I can only use the first two, all others give errors, but I cannot adjust brightness with any of them.

Does adjusting xgamma helps? Like, type in a terminal:

xgamma -gamma 2

your screen will get brighter. Go ahead and run mplayer to see if it helps

Good luck!

Yes, Megaman X, I can use xgamma. But that becomes really inconvenient at times. If I want to change the brightness when I'm watching a movie, then I have to pause it, and open a terminal, and then use xgamma. I want to set brightness using mplayer itself. I could do this earlier, in Slack 9.1.

Probably your only option is us a video filter option like here:

mplayer -vf eq=60:50 movie.wmv

using -vf eq=60:50
sets my brightness ratio 60:100 and contrast ratio 50:100... Play with the diff percentages until you get what you like... It's not on the fly but better the xgamma...
