When using XV with textured video, which ever value I set the two advertised attributes XV_BRIGHTNESS and XV_CONTRAST, the video always looks identical. If I force the usage of video overlay, then those attributes works fine (and the other advertised attributes seem to also have effect). So there is a bug with XV textured video: either the attributes are advertised, and then have some effect, or they should not be proposed. How to reproduce: 1. mplayer my-favourite-video.ogc 2. play with attributes pressing 1, 2, 3, and 4 => nothing happens 1. mplayer -vo xv:port=1 my-favourite-video.ogc 2. play with attributes pressing 1, 2, 3, and 4 => your favourite video gets a hard time Version: intel 2.5.0 xserver 1.4.2 Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller
yep, 915/945 texture video should have support for that, we've done that for 965G yet. It's on TODO, but lack time for now.
sorry we have not done that yet.
give it to haihao as media bug.. let's not to let this bug dead if what needed is a doable fix
The G45 has the same problem, and of course it doesn't have an overlay mode, only textured video.
Any idea when this will be implemented?
Same problem on Arrandale. I first saw this problem on 965 some two years (!) ago but it was tolerable there because there was also the overlay support. However, Arrandale only has textured video support.

This is still an issue nearly three (!!) years later. Also it seems the XV_HUE, XV_SATURATION, and XV_GAMMA video attributes are missing (see bug #39606).

Yeah, I've basically given up on this embarrassing shortcoming ever getting addressed, and have bought a proper HDTV to watch movies. Much more comfortable anyway. For the rare occasion when I need to use Xvideo on my computer, I found the old little "xcalib" utility to be invaluable. It can adjust contrast, brightness, and gamma. It can even be used for lightweight color calibration, e.g., to remove the blue tint common on many cheaper laptop screens. It works on a system-wide basis so it affects not only mplayer or vlc, but also your web browser, including flash videos. <rant> It's kind-of amazing that the same functionality is not integrated into full-blown desktop environments such as KDE. I guess it's simply an indication that hardly anybody in the Linux world cares about these things -- flicker-free boot is clearly *so* much more important. </rant>
