@moq/hang

Core media library for Media over QUIC (MoQ). Provides shared primitives used by @moq/watch and @moq/publish, built on top of @moq/lite.

Features

• Catalog — JSON track describing other tracks and their codec properties (audio, video, chat, location, etc.)
• Container — Media framing in two formats: CMAF (fMP4) and Legacy (varint-timestamp + raw codec bitstream)
• Utilities — Hex encoding, Opus audio polyfill (libav), latency computation, browser detection workarounds

Browser support detection is provided by <moq-watch-support> and <moq-publish-support>.

npm add @moq/hang
# or
pnpm add @moq/hang
