11 Some video output devices can overlay a framebuffer image onto the
35 Framebuffer section in Video Output Overlay Interface
38 Contrary to the *Video Overlay* interface the framebuffer is normally
40 accessible as a framebuffer device (``/dev/fbN``). Given a V4L2 device,
41 applications can find the corresponding framebuffer device by calling
43 other information, the physical address of the framebuffer in the
45 The framebuffer device ioctl ``FBIOGET_FSCREENINFO`` returns the same
51 The width and height of the framebuffer depends on the current video
53 (or any other ioctl which would imply a framebuffer size change) with an
54 ``EBUSY`` error code until all applications closed the framebuffer device.
