Hi all
This is my c++ code which I use to capture screen:
Display* display = XOpenDisplay(NULL);
Window root = DefaultRootWindow(display);
XWindowAttributes attributes = {0};
XGetWindowAttributes(display, root, &attributes);
int width, height;
width = attributes.width;
height = attributes.height;
XImage* img = XGetImage(display, root, 0, 0 , width, height, AllPlanes,
ZPixmap);
...
XDestroyImage(img);
XCloseDisplay(display);
When I run it without Xvfb I get a normal screen picture. However, when I use
it in Xvfb is not not normal. For example I tried to capture youtube in firefox
as a result I see some green/blue image with you tube pieces.
This question was asked on stackoverflow
http://stackoverflow.com/questions/42110050/xlib-and-xvfb-capture-screen
and there can be seen the result image.
How to fix it?
