You can use HTML overlays with StageVideo to display UI elements in the Flash display list video plane. This plane is above the StageVideo plane, so StageVideo always displays behind any Flash display list elements.
HTML overlays are UI elements that you can display in the Flash display plane on video that is rendered by
StageVideo on its own plane. Before Flash 15, you could not use HTML overlays when hardware acceleration was not available. Starting in Flash 15, HTML overlays display when
StageVideo falls back to software rendering.
Depending upon your system’s capabilities, performance can degrade to a greater or lesser degree when you use HTML overlays.
