I am working on a Linux based embedded system. It uses Qt for windowing and there is no x-server. My aim is to take screen shot of the screen. I have tried using FBgrab. It failed since i don't have a /dev/fb0 since the frame buffer is not enabled in the kernel. We are running a qt based application to show ui on the screen (hdmi).
When I try to take a screen shot on my tablet by pressing power and volume down button simultaneously for 1 full second, U get the screen shot of everythin except youtube video that is playing on the screen. Anyone know why the creen shot is blanked out on the youtube video. and how to get around this. I had another tablet where this was not a problem.
