Typical backends

Caveats

• I/O contractThe bound slot is a directory whose files are decoded in sorted order; pin it at a single file for a deterministic test.
• LimitationPlayback runs at each source's native frame rate with no rate override, so high-FPS or high-resolution files can overwhelm a slow downstream consumer.
• I/O contractFrames are emitted in BGR colour order, and each carries a host monotonic timestamp taken at emission rather than the original presentation timestamp.
• Parameter interactionwidth and height left at the sentinel keep the source resolution on that axis; setting either triggers a rescale that does not preserve aspect ratio on its own.
• State lifetimerepeat loops the playlist when on and stops after one pass when off; the bound slot, width, height, and repeat are hot-swappable, and changing the slot restarts from the new directory.
