/**
 * dash.js HEVC Plugin — Enables HEVC playback in dash.js via WASM transcoding.
 *
 * Patches MSE and registers a capabilities filter so dash.js accepts HEVC
 * representations and transparently transcodes them to H.264.
 *
 * Usage:
 * ```ts
 * import dashjs from 'dashjs';
 * import { attachHevcSupport } from 'hevc.js/dash';
 *
 * const player = dashjs.MediaPlayer().create();
 * const cleanup = await attachHevcSupport(player, { wasmUrl: '/hevc-decode.js' });
 * player.initialize(videoElement, mpdUrl, true);
 * ```
