Hi, I am porting my custom frontend to VirtualBox 5.0 and had a couple of questions about how IFramebuffer works now. I see that all the stuff regarding VRAM and implementing it inside the framebuffer is gone, which I was told would happen. What confuses me is usage of notifyUpdate vs notifyUpdateImage. I am launching the machine inside my own process - so then which is the most efficient way to receive notifications about updates? Which one is more efficient? As I understand if I use notifyUpdate (and do not retur the UpdateImage capability) I must get the pointer to the bitmap and all the data from the IDisplaySourceBitmap interface? Is that thread safe? Can I read the pixels without any explicit locking? And what about changes to the pixel format - they are no longer part of the notifications. Does that mean I need to call IDisplaySourceBitmap::queryBitmapInfo() each time i receive a notifyUpdate call?
Best Regards, Rudolfs Bundulis
