Crate hang 

hang: WebCodecs compatible media encoding for MoQ

Media-specific library built on moq_net for streaming audio and video with WebCodecs.

Each hang broadcast consists of:

• Catalog: A JSON track containing codec info and track metadata, updated live as tracks change.
• Tracks: Audio or video, supporting one or more renditions.
• Timeline: A JSON track indexing the broadcast’s aligned segments (one or more groups each), so a consumer can seek (or build indexes/playlists) without downloading media. Advertised by the catalog’s archive entry.

Each track specifies a container format:

• Legacy: A timestamp followed by the codec payload.
• CMAF: Fragmented MP4 container (moof+mdat pair)

See the moq-mux crate for importing existing media formats into hang broadcasts.
