Data Structures
struct	video_frame_t
	When code needs to work with simple frame swap, it keeps current_frame, frame_a, frame_b, use_frame_a here instead of scattering it across globals. Initialization establishes the handles and sizes; teardown must release any allocation, lock, thread, or callback context recorded in those fields. More...
struct	video_frame_buffer_t
	One captured, decoded, or rendered video frame and its timing metadata. More...
struct	video_frame_stats_t
	Counters and timing measurements used to monitor frame delivery and quality. More...
struct	simple_frame_swap_t
	Counters and timing measurements used to monitor frame delivery and quality. More...

Macros
#define	VIDEO_FRAME_BUFFER_SIZE   MAX_FRAME_BUFFER_SIZE
	Video frame buffer size (2MB per frame).
#define	MAX_FRAME_BUFFERS   2
	Maximum number of frame buffers (double buffering).
