## What it is
A JavaScript/WebAssembly media decoder and player for Ogg Vorbis, Opus, Theora, and WebM VP8/VP9/AV1 video, built by compiling native codec libraries with Emscripten. It enables playback of these formats in browsers that lack native support.

## Use cases
- play Ogg Theora video in a browser without native support
- decode Vorbis and Opus audio in JavaScript
- play WebM VP8/VP9/AV1 video via WebAssembly
- add fallback media playback for legacy codecs on the web
- stream and decode video files client-side in the browser

## When to choose
- you need to play Ogg/Theora or other codecs the browser doesn't support natively
- you want a pure client-side decoder with no server transcoding
- you need WebAssembly-based media decoding with streaming support

## When to avoid
- the browser natively supports your media formats
- you need low-power or low-latency playback where native decoding is far faster
- you need IE or legacy browser support
