Thanks Robert for the suggestion.
I implemented the feature based on osgscreencapture.cpp for the case
"--pbuffer-only".
However the code still has two problems:
1) I get the following warning
PixelBufferX11::init(), pbuffer created with different size then requsted
Requested size (800,600)
Pbuffer size (0,0)
Pixel buffer has been created successfully.
If I let it pass the video creation works fine, but I get weird
drawings on my screen (on the whole desktop, independent of any
window). If I add a check for the pixel buffer size after creation,
well it is always empty. Without the pbuffer feature the application
works fine.
2) Independent of the previous issue, if I run the application in a
console (out of X) I get the following error
Error: Unable to open display ":0.0".
GraphicsWindow has not been created successfully.
Error: Unable to open display ":0.0".
std::exception was raised: ColladaRenderer::ColladaRenderer failed to
create the pixel buffer
so it seems that the viewer still tries to create the GraphicsWindow.
Where in the code can I check if the viewer will try to create a
GraphicsWindow ?
What do you think I am doing wrong ?

rodrigob.
