Detailed Description

Counters and timing measurements used to monitor frame delivery and quality.

Simple atomic frame swap structure

Simplified frame management for basic use cases that don't need statistics. Uses atomic pointer swaps for lock-free frame updates. This is the pattern used by many video streaming services for simple frame delivery.

Note

This is a lighter-weight alternative to video_frame_buffer_t when statistics tracking is not needed.

Uses two pre-allocated frames that alternate on each update.

Atomic pointer swap enables lock-free operation.
