Introducing AVAL
A new open-source format for interactive video on the web, with a built-in state machine, frame-accurate transitions, and packed-alpha transparency.
Key features
- Deterministic state graph
- Package named states, authored triggers, and latest-wins routing in the asset.
- Frame-accurate routes
- Start transitions on authored content frames using portals, finishes, cuts, and reversals.
- Seekless loops
- Keep the decoder timeline moving forward across loop seams instead of seeking.
- Packed-alpha transparency
- Composite transparent prerendered motion with a packed-alpha WebGL2 renderer.
- Web-native runtime
- Decode with WebCodecs and present with WebGL2, without a mandatory WASM runtime.
- Structured failure
- Raise one bounded error so the application can choose its own response.
