## What it is
Jessibuca is an open-source pure HTML5 live-streaming video player built on MediaSource, WebCodecs, and WebAssembly, with WebGL rendering and WebAudio playback. It decodes H.264/H.265 with AAC/G711 audio in the browser without plugins, achieving sub-second latency across PC, Android, and iOS webviews.

## Use cases
- play live video streams in the browser without plugins
- play http-flv or websocket-flv streams in H5 pages
- achieve sub-second low-latency live streaming in browsers
- play H.265 video in browsers that lack native HEVC support
- embed surveillance camera streams (GB28181) in a web page
- autoplay live video inside WeChat H5 webviews
- record live streams to MP4 or WebM in the browser
- render multiple live video tiles with multi-instance playback

## When to choose
- you need plugin-free live streaming playback in mobile or desktop browsers
- you must play H.265/HEVC or G711 streams where native browser codecs fail
- you need very low latency (under 1 second) for live monitoring or surveillance
- you want wasm soft-decode fallback plus MediaSource/WebCodecs hard-decode acceleration
- you need many simultaneous player instances with worker-based decoding

## When to avoid
- you only need VOD playback of standard MP4/HLS files, which native video elements handle
- you need a full streaming server rather than a client-side player
- your project cannot accept GPL-3.0 licensing terms
- you require guaranteed support for Pro features without a commercial license
- you target environments without WebAssembly or modern browser APIs
