hybrid-dump for VDPAU accelerated video playing on Ubuntu 11.10 with bumblebee 3.0?

Watching videos with hardware acceleration enabled gives me sound but no image

I have managed to successfully compile and run hybrid-windump both from gebart and harp1n. I am using Bumblebee 3.0.1 with x-swat drivers 304.64 under Xubuntu 12.04 with Nvidia GT 525M.


DISPLAY=:8 optirun mplayer -vo vdpau videofilename

In another window

DISPLAY=:8 metacity --replace

And in yet another window

./windump :8 :0.0

Regardless if I compile either of the windump sources with or without included xorg.conf (using respectively gcc and make) The result is always the same. The displayed windump screen is entirely black.

Mplayer reports the following

I get the following image There seems to be a window inside of that area, although I am unable to move, resize or close it. The same happens when running glxspheres, but the invisible window has different size and takes up the whole black area.

Can anyone help me out with getting the image display correctly?
