Player Behavior

This page explains how players consume DP-1 playlists at runtime.

• What this is: runtime behavior guidance for playback clients.
• Why use it: helps debug validation, fetch, and playback issues.
• What to do next: confirm your player behavior against the canonical DP-1 spec.

Version and compatibility note

• Canonical DP-1 spec is currently v1.1.0.
• Some adjacent tooling still centers dpVersion: 1.0.0 payloads and legacy top-level signature behavior.
• Do not assume blanket end-to-end 1.1.0 parity across CLI, validator, and feed operator unless explicitly verified in those repos.

Runtime sequence (player view)

1. Load playlist from URL or feed endpoint.
2. Validate playlist structure for the toolchain version in use.
3. Verify trust metadata (signature or signatures) according to implemented verifier capabilities.
4. Render items in order with item/default display settings.
5. On failure, surface a clear error and continue according to player policy.

FF1 as reference hardware

FF1 is Feral File's art computer and a reference hardware path for DP-1 playback.

Use FF1 behavior as one implementation path, not as the protocol definition.
