Gamma correction on vdpau+overlay not possible?
I tried to change the gamma while watching an hardware decoded video via vdpau.
Using mplayer it doesn't work, using xgamma doesn't work (all the desktop changes, but the video window).
I read that is possible to disable the usage of the overlay surface to force the blit routines that should follow at least the xgamma settings;
But doesn't that means tearing?
