d'oh, baka me!
sry, of course I have the IA32 driver 4191, messed up a bit with the versions..
here's my output with xvinfo (is the same on 4191 and previous 3123, though) :
Code:
number of attributes: 4
"XV_DOUBLE_BUFFER" (range 0 to 1)
client settable attribute
client gettable attribute (current value is 1)
"XV_COLORKEY" (range 0 to 16777215)
client settable attribute
client gettable attribute (current value is 66046)
"XV_AUTOPAINT_COLORKEY" (range 0 to 1)
client settable attribute
client gettable attribute (current value is 1)
"XV_SET_DEFAULTS" (range 0 to 0)
client settable attribute
as you see, no XV_BRIGHTNESS (and to speak of it, neither XV_SATURATION nor XV_HUE)
sry again, hope anybody knows something about it...
bye
