Format identifiers describe the current draft generation, not a stable compatibility promise.

SYSTEM MODEL

Designed for bounded, indexed playback

Avelune container and decoding architectureA front index addresses independent epochs containing audio and video packets. Decoders reconstruct media for presentation.FRONTINDEXEPOCHRANGESPACKETSALV1 / ALA1RANGEFETCHWASMDECODEY′CbCr+ PCM

The container’s CRC-protected front index identifies independently fetchable epochs. The browser demo requests byte ranges, decodes the project’s own bitstreams in WebAssembly, and presents Y′CbCr frames with WebGPU or Canvas2D.
