Hi, This is with reference to OMAP3530 platform which has video window and OSD window. SurfaceFlinger uses OSD window for rendering UI - /dev/fb0 or /dev/ graphics/fb0 Overlay module uses Video window to rendering video - /dev/video1 or / dev/video2
When overlay module is initialized using the Surface information it accordingly renders video in the region defined by the Surface. i.e like punching a hole in the surface and render the video. Overlay module makes direct V4L2 calls. Is my understanding correct ?
