## What it is
A complete web-based H.265 (HEVC) video player solution built in JavaScript. It uses JS-based stream demuxing, WebAssembly (FFmpeg) video decoding, Canvas rendering for video frames, and AudioContext for audio playback, since browsers lack native H.265 support.

## Use cases
- play H.265/HEVC video in the browser
- build a custom web video player with H.265 support
- decode HEVC video using WebAssembly and FFmpeg
- render YUV video frames on a canvas
- stream HLS content with H.265 codec in a web app
- learn how web video players and WASM decoding work internally

## When to choose
- you need to play H.265/HEVC video in browsers that lack native support
- you want a customizable, open-source player foundation to build business logic on
- you prefer software decoding via WASM without native plugins
- you want to study player architecture (demuxing, decoding, rendering)

## When to avoid
- you only need H.264/AVC playback, which browsers support natively
- you need hardware-accelerated decoding for low-power devices
- you require a production-ready player with extensive business features out of the box
- you need broad protocol support beyond HLS
