 # 默认视频播放问题修复
 ## 问题描述
 在性能优化过程中，发现默认视频 `d-3s.mp4` 和 `s-1.mp4` 没有正常播放的问题。
 ## 问题原因
 1. **缓存策略过于激进**: 将缓存数量从3个减少到2个，导致重要视频被过早清理
 2. **缺少默认视频启动调用**: 在 `startCall()` 方法中没有调用 `startDefaultVideoStream()`
 3. **重要视频保护不足**: 没有区分重要视频和普通视频的清理策略
 ## 修复措施
 ### 1. 优化缓存策略
 ```javascript
 // 修复前
 if (this.videoStreams.size >= 2) { // 缓存数量过少
    const firstKey = this.videoStreams.keys().next().value;
    // 直接清理第一个视频，可能包括重要视频
 }
 // 修复后
 if (this.videoStreams.size >= 4) { // 增加缓存数量
    const importantVideos = [this.defaultVideo, 's-1.mp4', 'd-3s.mp4'];
    const videoToRemove = cachedVideos.find(video => !importantVideos.includes(video));
    // 只清理非重要视频
 }
 ```
 ### 2. 添加默认视频启动调用
 ```javascript
 async startCall() {
    // ... 其他代码 ...
    // 启动默认视频流
    await this.startDefaultVideoStream();
    // 通知服务器通话开始
    this.socket.emit('call-started');
 }
 ```
 ### 3. 改进预加载策略
 ```javascript
 async preloadCommonVideos() {
    const videosToPreload = new Set([]);
    // 添加重要视频（默认视频和常用视频）
    videosToPreload.add(this.defaultVideo); // 默认视频
    videosToPreload.add('s-1.mp4'); // 常用视频
    videosToPreload.add('d-3s.mp4'); // 默认视频的另一个版本
    // 添加视频映射中的所有视频
    Object.values(this.videoMapping).forEach(video => {
        videosToPreload.add(video);
    });
 }
 ```
 ### 4. 优化性能监控清理
 ```javascript
 // 如果缓存过多，清理一些（但保护重要视频）
 if (this.videoStreams.size > 5) {
    const importantVideos = [this.defaultVideo, 's-1.mp4', 'd-3s.mp4'];
    // 只清理非重要视频
    const videosToRemove = cachedVideos.filter(video => !importantVideos.includes(video));
    videosToRemove.slice(0, 2).forEach(key => {
        this.cleanupVideoResources(key);
    });
 }
 ```
 ### 5. 调整性能测试阈值
 ```javascript
 // 检查视频流数量
 if (testResults.metrics.videoStreamsCount > 5) { // 从3增加到5
    // 报告问题
 }
 // 检查动画帧数量
 if (testResults.metrics.animationFramesCount > 3) { // 从2增加到3
    // 报告问题
 }
 ```
 ## 重要视频列表
 以下视频被标记为重要视频，不会被自动清理：
 - `d-3s.mp4` - 默认视频
 - `s-1.mp4` - 常用视频
 - 当前默认视频（`this.defaultVideo`）
 ## 测试功能
 添加了测试功能来验证默认视频播放：
 1. **测试按钮**: "测试默认视频" 按钮
 2. **测试方法**: `testDefaultVideoPlayback()`
 3. **测试流程**:
   - 检查默认视频文件是否存在
   - 创建默认视频流
   - 设置到视频元素并播放
   - 5秒后自动停止测试
 ## 验证步骤
 1. 启动应用
 2. 点击"开始音频通话"
 3. 观察默认视频是否开始播放
 4. 点击"测试默认视频"按钮验证功能
 5. 查看性能监控面板确认视频流数量
 ## 预期效果
 修复后，默认视频应该能够：
 1. **正常播放**: 通话开始时自动播放默认视频
 2. **不被清理**: 重要视频不会被自动清理机制删除
 3. **快速切换**: 预加载确保切换时响应迅速
 4. **稳定运行**: 性能监控不会误报重要视频为问题
 ## 监控指标
 - **视频流数量**: 正常范围 1-5 个
 - **重要视频保护**: 确保 `d-3s.mp4` 和 `s-1.mp4` 不被清理
 - **默认视频状态**: 通话开始时应该显示默认视频
