- 按 URL 扩展名自动识别插件(.m3u8→hls.js,.flv/.ts/.m2ts→mpegts.js),iOS 上 m3u8 仍走原生 HLS - flv 播放改由 mpegts.js 承担,移除 flv.js 依赖,plug:'flv.js' 保留兼容别名 - 修复 plug:'dash.js' 调用不存在函数的死代码 bug - mpegts 能力判断由 mseLivePlayback 放宽为 isSupported()(修复部分浏览器点播被误杀) - 移动端:iOS 原生全屏状态同步、iPad/iPod UA 识别、X5 同层播放属性、进度/音量条触摸拖动、触摸坐标滚动偏移修正 - 新增 Playwright 冒烟测试(npm test)与支持 Range 的本地服务器(npm run serve) - 文档说明:测试禁用 python http.server(不支持 Range,mp4 无法 seek)
