Per discussion in #5018, this adds a reference sample for hevc.js, an HEVC software fallback plugin for dash.js.
The sample shows how to play HEVC (H.265) DASH streams in dash.js on browsers without native HEVC support (Firefox, Chrome on Linux/Windows, etc.). The @hevcjs/dashjs-plugin package patches MSE so that HEVC samples are transcoded to H.264 inside a Web Worker (WASM H.265 decoder + WebCodecs H.264 encoder). The underlying
<video>element keeps playing a standard H.264 stream, so ABR, audio sync, and seeking all work unchanged.A new
hevc.jssection is added tosamples.json(alongside the existing LCEVC section). The sample HTML is self-contained and pulls the plugin from esm.sh (ESM, no build step) plus the WASM / Worker assets from unpkg.cc @dsilhavy
