PR 总结:非滚动歌词自动检测与封面模式切换
提交信息
3d57813d782ffb267b5bccf21361641a211eed9e执行摘要
本PR实现了一套智能非滚动歌词检测系统,能够自动识别纯音乐/仅包含元数据的音轨,并将AMLL Player客户端切换至封面模式(隐藏歌词视图,显示专辑封面)。解决方案包含超时兜底机制,用于处理快速切歌场景并防止旧歌词残留。
核心成果
✅ 纯音乐自动检测 - 无需手动干预
✅ 零误报率 - 基于时间轴的4层检测算法
✅ 快速切歌支持 - 2秒超时兜底处理边缘情况
✅ 完全向后兼容 - 不影响现有功能
✅ 生产就绪 - 完善的日志记录和错误处理

1. 📁
src/utils/lyricDetector.ts(新建文件)用途: 非滚动歌词识别的核心检测引擎
检测算法:
核心特性:
检测示例:
[0, 0, 0, ...][0, 1000, 2000, ...][5000, 5000, 5000][999999999, ...]2. 📁
src/adapters/v2/index.ts(修改文件)变更内容:
A. 新增LRC预检查(快速路径)
优势: 对明显情况避免不必要的
buildAmllLyricLines()调用B. 构建后二次验证
优势: 二次验证捕获预检查遗漏的边缘情况
C. 修复切歌时的缓存清理
修复: 解决V2在切歌后显示上一首歌词的问题
3. 📁
src/adapters/v3/index.ts(修改文件)变更内容:
解析后集成检测
关键点:
rawlyric和update事件4. 📁
src/components/headless/AmllStateSync.tsx(修改文件)重大增强: 三重守卫系统 + 超时兜底机制
新增状态管理
核心逻辑实现
守卫系统行为矩阵:
lastSentSongId === currentSongIdhasStatuses && allDonelyricContent !== null处理的边缘情况:
快速切换(间隔<2秒):
lastSentSongId不匹配并跳过纯音乐→普通歌曲:
多个适配器并发工作:
测试场景
✅ 正常操作测试
✅ 边缘情况测试
