Hi,
for colorkeying did not work with the following onboard graphic:
00:02.0 VGA compatible controller: Intel Corporation 82852/855GM Integrated
Graphics Device (rev 02)
Softdevice OSD was only shown in that area where no video was drawn.
Base thread of this discussion (in german) is here:
http://www.vdr-portal.de/board/thread.php?threadid=54640
Allthough it is still unresolved for original reporter, the attached patch
solves the issue for me.
Changes are similar to code from Xorg:
http://webcvs.freedesktop.org/xorg/driver/xf86-video-i810/src/i830_video.c?annotate=1.22
line 508 .
