+	  Enables a virtual video driver. This driver emulates a webcam,
+	  TV, S-Video and HDMI capture hardware, including VBI support for
+	  the SDTV inputs. Also video output, VBI output, radio receivers,
+	  transmitters and software defined radio capture is emulated.
+
+	  It is highly configurable and is ideal for testing applications.
+	  Error injection is supported to test rare errors that are hard
+	  to reproduce in real hardware.
+
+	  Say Y here if you want to test video apps or debug V4L devices.
+	  When in doubt, say N.

+ * video output buffer that is and which part of the video capture buffer
+ * so we can scale the video straight from the output buffer to the capture
+ * buffer without any intermediate steps.
+ *
+ * If we need to deal with an output overlay, then there is no choice and
+ * that intermediate step still has to be taken. For the output overlay
+ * support we calculate the intersection of the framebuffer and the overlay
+ * window (which may be partially or wholly outside of the framebuffer
+ * itself) and the intersection of that with loop_vid_copy (i.e. the part of
+ * the actual looped video that will be overlaid). The result is calculated
