i want to start automatically multiple VNC sessions and read capture the
video buffers for each of the X displays being used.
I'm able currently to do this by using Xvfb;
Xvfb :1 -screen 0 1024x768x24 -fbdir vfb_test/fbdir &
run applications in the assigned X display
export DISPLAY=localhost:1.0
firefox &
and directly access the framebuffer.
ifstream file ("vfb_test/screen0_0" , ios::in | ios::binary | ios::ate);
The only downside is that this uses software rendering, so i'm hoping that
virtualGL/turboVNC can help me achieve the same goal without sacrificing
hardware acceleration.
Any ideas how should i approach this problem?
