When I play videos in Totem or VLC using XVideo, the picture is too light and colorful. I have to reduce contrast and saturation manually to get the proper picture.
Used package versions:
- linux 3.1
- libdrm 2.4.26-1
- xf86-video-intel 2.16.0
- xorg-server 18.104.22.1681
It was already happened with an older kernel and xorg. I tried to make a screenshot to showing the difference between with and without XVideo, but XVideo's area doesn't saved to image file (shows only a black box).
Steps to reproduce:
1. Start playing a video with default settings in an XVideo-based media player.
2. Start playing an another video in an another media player window.
3. Compare the two picture.
The values are passed through unmolested to the hw, so I think this is a case of wontfix...
How can I fix it? Do you think that it's a hardware error?
Probably it is the hardware fault. It does not behaves correctly, even when it receives the right values.
I found that I have the same problem that was reported 5 years ago: https://bugs.launchpad.net/totem/+bug/32963
It happens only after I launch Totem 3.0. However there is no problem with Totem 3.2, which uses 3D acceleration instead of XVideo. But it's extremely slow due ShadowFB, which I have to enabled to avoid the random GPU hangs.
Ok, it's a bug only with Totem 3.0, no problem with Totem 2.32. It's not a driver problem, so I marked this problem as not our bug.
