Displaying Hardware Accelerated Video on X Window Systems

摘要

Multiple planes may be used to enhance the video experience in hardware accelerated video in X window systems. A composite window manager, cursor theme, and more than two ARGB format planes may be used. The window manager handles a transparent area. The area that shows the video is defined as a cutout area. Before the window manager redraws a specific window with the cutout area, the area is set to be transparent or translucent. Then the video can be seen through the cutout with or without overlaid translucent graphics. The cursor theme provides opaque cursors.
