struct {
uint16_t   x0
	top-left x coordinate
uint16_t   y0
	top-left y coordinate

Detailed Description

Application-allocated frame buffer for ARGB overlays.

When using application-allocated frame buffer DRAW events are executed by libbluray. Application needs to handle only OPEN/FLUSH/CLOSE events.

DRAW events can still be used for optimizations.

buf

uint32_t* BD_ARGB_BUFFER::buf[4]

[0] - PG plane, [1] - IG plane.

[2], [3] reserved for stereoscopic overlay.

[struct]

struct { ... } BD_ARGB_BUFFER::dirty[2]

Dirty area of frame buffers.

• Updated by library before lock() call.
• Reset after each BD_ARGB_OVERLAY_FLUSH. [0] - PG plane, [1] - IG plane
