## What it is
A browser-based HEVC/H.265 (and H.264/AV1) video player SDK supporting live and VOD playback over HTTP-FLV, HLS, MP4, TS, WebSocket, and WebRTC. It uses WebCodec, WASM (with SIMD), and MSE for software and hardware-accelerated decoding.

## Use cases
- play h265 video in the browser
- hevc live streaming web player
- play http-flv h265 stream
- hls m3u8 h265 playback
- webrtc h265 playback in browser
- wasm video decoder for hevc
- play mp4 h265 with hardware decoding
- embed h265 player in web app

## When to choose
- you need to play H.265/HEVC video in browsers that lack native support
- you need broad protocol coverage (HTTP-FLV, HLS, TS, WebSocket, WebRTC) for live and VOD
- you want hardware decoding via WebCodec with WASM fallback
- you need snapshots, MediaInfo probing, or multi-instance playback

## When to avoid
- you only need H.264 playback, which native HTML5 video handles
- you need a native/mobile player rather than a web SDK
- you require a permissively licensed library (GPL-3.0 / custom license)
- you need server-side transcoding rather than client playback
