[Bug 32963] Re: Xv movies on 810/i945 gives horrible color, Gamma

[Iain Murray]

I have similar washed out videos under some circumstances with an "Intel
Corporation 82852/855GM Integrated Graphics Device" using the i810
driver. This is a Dell Inspiron 710m. I'm running 6.06 LTS originally
installed from an official CD with whatever updates apt offered me.

My impression is that it is a totem-xine and gxine bug.

If I watch movies with xine (from the xine-ui package) or mplayer after
an X restart then everything is fine. xvattr information (given later)
is not changed by running xine or mplayer.

Movies under totem (totem-xine) are washed out. The values reported by
xvattr change, but are reset after closing totem. Moves subsequently
play ok in xine or mplayer. Totem can also play movies fine if xvattr
values are fixed after starting totem.

Movies under gxine are washed out, xvattr values are changed (although
not to same values as by totem) and stay changed. Movies in xine or
mplayer are washed out until an X restart or xvattr stuff changed back
by hand. Again gxine plays fine if fix xvattr values by hand while gxine
running.

I get the following xvattr output after X restart: and stays the same after running xine(-ui) or totem(-xine):
% xvattr

The values are reset after closing totem, but while it is running I get:
% xvattr

After running (and closing) gxine I get:
% xvattr
Found Xv 2.2

 Port: 73
  Name: XV_COLORKEY
   Flags: XvGettable XvSettable

  Name: XV_CONTRAST

   Current value: 128

I've been fixing color washouts by running:
    xvattr -a XV_CONTRAST -v 48 ; xvattr -a XV_BRIGHTNESS -v -5

Why (with the default settings, which I haven't touched) don't
totem/gxine just leave the xvattr settings alone?
