 Using the overlay filter to overlay video from a webcam onto x11grab
 causes many dropped frames. The frames seem to come in short bursts
 followed by a large number of dropped frames. This is easily seen by
 inserting showinfo into the x11grab stream before it is sent to the
 overlay filter. The attached file shows this behaviour. If the overlay
 filter isn't used, the frames appear to have approximately the correct
 timestamps as shown in the second attachment.
