+
+## 🚀 快速开始
+
+### 1. 基础使用
+
+```tsx
+import { VideoEditOverlay } from '@/components/pages/work-flow/video-edit';
+
+function MyVideoPlayer() {
+  const videoRef = useRef<HTMLVideoElement>(null);
+  
+  const handleDescriptionSubmit = (editPoint, description) => {
+    console.log('编辑请求:', { editPoint, description });
+    // 发送到聊天系统或处理编辑请求
+  };
+
+  return (
+    <div className="relative">
+      <video ref={videoRef} src="your-video.mp4" />
+      
+      <VideoEditOverlay
+        projectId="your-project-id"
+        userId={123}
+        currentVideo={{
+          id: 'video-id',
+          url: 'your-video.mp4',
+          duration: 30
+        }}
+        videoRef={videoRef}
+        enabled={true}
+        onDescriptionSubmit={handleDescriptionSubmit}
+      />
+    </div>
+  );
+}
+```
+
+### 2. 集成到MediaViewer
+
+```tsx
+// 在MediaViewer组件中
+<VideoEditOverlay
+  projectId={taskObject.project_id}
+  userId={currentUser.id}
+  currentVideo={{
+    id: currentVideo.video_id,
+    url: currentVideo.urls[0],
+    duration: 30
+  }}
+  videoRef={mainVideoRef}
+  enabled={isVideoEditMode}
+  onDescriptionSubmit={handleVideoEditDescriptionSubmit}
+  className="rounded-lg"
+/>
+```
+
+## 📱 响应式设计
+
+### 屏幕适配
+- **桌面端 (≥1024px)**: 完整功能，hover效果
+- **平板端 (768-1023px)**: 增大点击区域

+- 防止iOS缩放 (font-size: 16px)
+- 触摸反馈动画
+
+## 🎮 交互说明
+
+### 键盘操作
+- **ESC**: 取消当前编辑
+- **Ctrl+Enter**: 提交描述
+- **Tab**: 在输入框内导航
+
+### 鼠标操作
+- **单击视频**: 创建编辑点
+- **单击编辑点**: 选择并显示输入框
+- **点击外部**: 自动提交或取消
+
+### 触摸操作
+- **轻触视频**: 创建编辑点
+- **轻触编辑点**: 选择编辑点
+- **长按**: 显示上下文菜单
+
+## 🔌 API集成
+
+### 编辑点CRUD操作
+
+```typescript
+import { 
+  createEditPoint, 
+  updateEditPoint, 
+  deleteEditPoint, 
+  getEditPoints 
+} from '@/components/pages/work-flow/video-edit';
+
+// 创建编辑点
+const editPoint = await createEditPoint({
+  videoId: 'video-id',
+  projectId: 'project-id',
+  position: { x: 50, y: 30 },
+  timestamp: 15.5,
+  description: '需要添加字幕'
+});
+
+// 更新编辑点
+await updateEditPoint({
+  id: editPoint.id,
+  description: '更新后的描述',
+  status: 'edited'
+});
+
+// 获取编辑点列表
+const response = await getEditPoints({
+  videoId: 'video-id',
+  projectId: 'project-id'
+});
+```
+
+## 🎨 样式定制
+
+### CSS变量
+```css
+.video-edit-input {
+  --bg-color: rgba(0, 0, 0, 0.8);
+  --border-color: rgba(255, 255, 255, 0.2);
+  --text-color: rgba(255, 255, 255, 0.9);
+}
+```
+
+### 主题适配
+- 自动检测系统主题
+- 支持高对比度模式
+- 可访问性优化
+
+## 🧪 测试
+
+### 运行测试页面
+```bash
+# 访问测试页面
+http://localhost:3000/test/video-edit
+```
+
+### 测试清单
+- [ ] 编辑点创建和动画
+- [ ] 连接线绘制
+- [ ] 输入框交互
+- [ ] 键盘操作
+- [ ] 响应式布局
+- [ ] 性能测试
+
+## 🔧 配置选项
+
+### VideoEditConfig
+```typescript
+interface VideoEditConfig {
+  maxEditPoints: number;        // 最大编辑点数量
+  autoSave: boolean;           // 自动保存
+  animationDuration: number;   // 动画时长
+  pointStyle: {
+    size: number;
+    color: string;
+    pulseColor: string;
+  };
+  connectionStyle: {
+    strokeWidth: number;
+    color: string;
+    dashArray: string;
+  };
+}
+```
+
+## 🚨 注意事项
+
+### 性能优化
+- 编辑点数量建议不超过20个
+- 使用虚拟化处理大量编辑点
+- 及时清理未使用的编辑点
+
+### 兼容性
+- 需要现代浏览器支持 (Chrome 80+, Firefox 75+, Safari 13+)
+- 移动端需要iOS 13+, Android 8+
+- 需要支持CSS Grid和Flexbox
+
+### 安全考虑
+- 输入内容需要XSS过滤
+- API调用需要身份验证

+# 🚀 视频编辑API部署指南
+
+## 📋 问题解决方案总结
+
+### 🔍 问题分析
+1. **根本原因**: 后端服务器 `https://77.smartvideo.py.qikongjian.com` 缺少 `/video-edit/edit-points` API端点
+2. **前端代码**: API调用代码正确，请求格式符合规范
+3. **配置正常**: 基础URL和认证机制工作正常
+
+### 🎯 解决方案
+
+我提供了三种解决方案，按优先级排序：
+
+## 🚀 方案一：立即可用的本地API路由（推荐）
+
+### ✅ 已实现的功能
+- ✅ Next.js API路由: `/app/api/video-edit/edit-points/route.ts`
+- ✅ 单点操作路由: `/app/api/video-edit/edit-points/[id]/route.ts`
+- ✅ 前端API自动切换: 优先使用本地API
+- ✅ Mock数据支持: 开发测试完全可用
+- ✅ 错误处理和重试机制
+
+### 🔧 使用方法
+```bash
+# 无需额外配置，功能已集成
+# 前端会自动使用本地API路由
+npm run dev
+```
+
+### 📊 API端点
+- `GET /api/video-edit/edit-points` - 获取编辑点列表
+- `POST /api/video-edit/edit-points` - 创建编辑点
+- `PUT /api/video-edit/edit-points/[id]` - 更新编辑点
+- `DELETE /api/video-edit/edit-points/[id]` - 删除编辑点
+- `POST /api/video-edit/edit-points/[id]/submit` - 提交编辑请求
+
+## 🏗️ 方案二：后端API实现（生产环境）
+
+### 📁 文件结构
+```
+backend/
+├── video_edit_api.py          # 主API实现
+├── requirements.txt           # 依赖包
+├── models/                    # 数据模型
+│   ├── edit_point.py
+│   └── database.py
+├── routers/                   # 路由模块
+│   └── video_edit.py
+└── middleware/                # 中间件
+    └── auth.py
+```
+
+### 🔧 部署步骤
+
+#### 1. 安装依赖
+```bash
+pip install fastapi uvicorn pydantic sqlalchemy psycopg2-binary
+```
+
+#### 2. 数据库设置
+```sql
+-- PostgreSQL 数据库表结构
+CREATE TABLE edit_points (
+    id VARCHAR(50) PRIMARY KEY,
+    video_id VARCHAR(100) NOT NULL,
+    project_id VARCHAR(100) NOT NULL,
+    user_id INTEGER NOT NULL,
+    position_x FLOAT NOT NULL CHECK (position_x >= 0 AND position_x <= 100),
+    position_y FLOAT NOT NULL CHECK (position_y >= 0 AND position_y <= 100),
+    timestamp FLOAT NOT NULL CHECK (timestamp >= 0),
+    description TEXT DEFAULT '',
+    status VARCHAR(20) DEFAULT 'pending',
+    created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP,
+    updated_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP
+);
+
+-- 创建索引
+CREATE INDEX idx_edit_points_video_project ON edit_points(video_id, project_id);
+CREATE INDEX idx_edit_points_user ON edit_points(user_id);
+CREATE INDEX idx_edit_points_status ON edit_points(status);
+```
+
+#### 3. 环境变量配置
+```bash
+# .env
+DATABASE_URL=postgresql://user:password@localhost/video_flow
+SECRET_KEY=your-secret-key-here
+CORS_ORIGINS=https://your-frontend-domain.com
+```
+
+#### 4. 部署到服务器
+```bash
+# 使用 Gunicorn + Uvicorn
+gunicorn video_edit_api:app -w 4 -k uvicorn.workers.UvicornWorker --bind 0.0.0.0:8000
+
+# 或使用 Docker
+docker build -t video-edit-api .
+docker run -p 8000:8000 video-edit-api
+```
+
+#### 5. Nginx 配置
+```nginx
+server {
+    listen 80;
+    server_name 77.smartvideo.py.qikongjian.com;
+
+    location /video-edit/ {
+        proxy_pass http://localhost:8000/video-edit/;
+        proxy_set_header Host $host;
+        proxy_set_header X-Real-IP $remote_addr;
+        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
+        proxy_set_header X-Forwarded-Proto $scheme;
+    }
+}
+```
+
+## 🔧 方案三：前端配置切换
+
+### 环境变量配置
+```bash
+# .env.local (开发环境)
+NEXT_PUBLIC_VIDEO_EDIT_USE_LOCAL=true
+
+# .env.production (生产环境)
+NEXT_PUBLIC_VIDEO_EDIT_USE_REMOTE=true
+NEXT_PUBLIC_VIDEO_EDIT_REMOTE_BASE=/video-edit
+```
+
+### 动态切换逻辑
+```typescript
+// 前端会自动检测API可用性并切换
+const config = getVideoEditApiConfig();
+if (config.useLocalApi) {
+  // 使用本地Next.js API路由
+} else {
+  // 使用远程后端API
+}
+```
+
+## 🧪 测试验证
+
+### 1. 功能测试
+```bash
+# 访问测试页面
+http://localhost:3000/test/video-edit
+
+# 测试API端点
+curl -X POST http://localhost:3000/api/video-edit/edit-points \
+  -H "Content-Type: application/json" \
+  -d '{
+    "video_id": "test-video",
+    "project_id": "test-project",
+    "position_x": 50,
+    "position_y": 30,
+    "timestamp": 15.5,
+    "description": "测试编辑点"
+  }'
+```
+
+### 2. 集成测试
+- ✅ 点击视频创建编辑点
+- ✅ 编辑点显示和动画
+- ✅ 输入框交互
+- ✅ 描述提交和保存
+- ✅ 编辑点删除
+- ✅ 多点管理
+
+## 📊 监控和日志
+
+### API监控
+```typescript
+// 前端监控
+const apiHealth = await checkApiHealth();
+console.log('API状态:', apiHealth);
+```
+
+### 错误处理
+```typescript
+// 自动重试和降级
+try {
+  const result = await createEditPoint(request);
+} catch (error) {
+  // 自动回退到Mock或缓存
+  const fallback = await attemptRecovery(error);
+}
+```
+
+## 🔒 安全考虑
+
+### 1. 认证授权
+- JWT token验证
+- 用户权限检查
+- 项目访问控制
+
+### 2. 数据验证
+- 输入参数验证
+- XSS防护
+- SQL注入防护
+
+### 3. 速率限制
+```python
+from slowapi import Limiter
+from slowapi.util import get_remote_address
+
+limiter = Limiter(key_func=get_remote_address)
+
+@app.post("/video-edit/edit-points")
+@limiter.limit("10/minute")
+async def create_edit_point(...):
+    pass
+```

+# 🎬 Video Edit API 完整规范文档
+
+## 📋 概述
+
+本文档为Video-Flow视频编辑功能的后端API提供完整的实现规范，包括RESTful API设计、数据结构定义、认证机制、数据库设计等，为后端开发团队提供详细的实现指南。
+
+## 🏗️ 系统架构
+
+### 技术栈建议
+- **后端框架**: FastAPI (Python) / Express.js (Node.js) / Spring Boot (Java)
+- **数据库**: PostgreSQL (主数据库) + Redis (缓存)
+- **认证**: JWT Token
+- **文件存储**: AWS S3 / 阿里云OSS
+- **消息队列**: Redis / RabbitMQ (用于异步处理)
+
+### 服务架构
+```
+Frontend (React) 
+    ↓ HTTP/HTTPS
+API Gateway 
+    ↓
+Video Edit Service
+    ↓
+Database (PostgreSQL) + Cache (Redis)
+```
+
+## 🗄️ 数据库设计
+
+### 1. 编辑点表 (edit_points)
+
+```sql
+CREATE TABLE edit_points (
+    id VARCHAR(50) PRIMARY KEY,
+    video_id VARCHAR(100) NOT NULL,
+    project_id VARCHAR(100) NOT NULL,
+    user_id INTEGER NOT NULL,
+    position_x FLOAT NOT NULL CHECK (position_x >= 0 AND position_x <= 100),
+    position_y FLOAT NOT NULL CHECK (position_y >= 0 AND position_y <= 100),
+    timestamp FLOAT NOT NULL CHECK (timestamp >= 0),
+    description TEXT DEFAULT '',
+    status VARCHAR(20) DEFAULT 'pending' CHECK (status IN ('pending', 'edited', 'processing', 'completed', 'failed')),
+    created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP,
+    updated_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP,
+    
+    -- 索引
+    INDEX idx_edit_points_video_project (video_id, project_id),
+    INDEX idx_edit_points_user (user_id),
+    INDEX idx_edit_points_status (status),
+    INDEX idx_edit_points_created (created_at DESC),
+    
+    -- 外键约束
+    FOREIGN KEY (user_id) REFERENCES users(id) ON DELETE CASCADE,
+    FOREIGN KEY (project_id) REFERENCES projects(id) ON DELETE CASCADE
+);
+```
+
+### 2. 编辑历史表 (edit_point_history)
+
+```sql
+CREATE TABLE edit_point_history (
+    id SERIAL PRIMARY KEY,
+    edit_point_id VARCHAR(50) NOT NULL,
+    action VARCHAR(20) NOT NULL CHECK (action IN ('created', 'updated', 'deleted', 'submitted')),
+    old_data JSONB,
+    new_data JSONB,
+    user_id INTEGER NOT NULL,
+    created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP,
+    
+    -- 索引
+    INDEX idx_history_edit_point (edit_point_id),
+    INDEX idx_history_user (user_id),
+    INDEX idx_history_created (created_at DESC),
+    
+    -- 外键约束
+    FOREIGN KEY (edit_point_id) REFERENCES edit_points(id) ON DELETE CASCADE,
+    FOREIGN KEY (user_id) REFERENCES users(id) ON DELETE CASCADE
+);
+```
+
+### 3. 编辑任务队列表 (edit_tasks)
+
+```sql
+CREATE TABLE edit_tasks (
+    id SERIAL PRIMARY KEY,
+    edit_point_id VARCHAR(50) NOT NULL,
+    task_type VARCHAR(20) NOT NULL DEFAULT 'edit_request',
+    priority INTEGER DEFAULT 0,
+    status VARCHAR(20) DEFAULT 'pending' CHECK (status IN ('pending', 'processing', 'completed', 'failed')),
+    payload JSONB NOT NULL,
+    result JSONB,
+    error_message TEXT,
+    retry_count INTEGER DEFAULT 0,
+    max_retries INTEGER DEFAULT 3,
+    scheduled_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP,
+    started_at TIMESTAMP,
+    completed_at TIMESTAMP,
+    created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP,
+    
+    -- 索引
+    INDEX idx_tasks_status (status),
+    INDEX idx_tasks_scheduled (scheduled_at),
+    INDEX idx_tasks_edit_point (edit_point_id),
+    
+    -- 外键约束
+    FOREIGN KEY (edit_point_id) REFERENCES edit_points(id) ON DELETE CASCADE
+);
+```

+    estimated_duration: number; // 预估处理时间（秒）
+  };
+}
+```
+
+### 7. 获取编辑统计
+
+```http
+GET /video-edit/stats
+```
+
+**查询参数:**
+```typescript
+interface GetStatsQuery {
+  project_id?: string;     // 可选：项目ID筛选
+  video_id?: string;       // 可选：视频ID筛选
+  date_from?: string;      // 可选：开始日期 (ISO 8601)
+  date_to?: string;        // 可选：结束日期 (ISO 8601)
+}
+```
+
+**响应格式:**
+```typescript
+interface GetStatsResponse {
+  code: number;
+  successful: boolean;
+  message: string;
+  data: {
+    total_edit_points: number;
+    status_breakdown: {
+      pending: number;
+      edited: number;
+      processing: number;
+      completed: number;
+      failed: number;
+    };
+    daily_stats: Array<{
+      date: string;
+      count: number;
+    }>;
+  };
+}
+```
+
+## 🔐 认证和权限控制
+
+### JWT Token 结构
+```typescript
+interface JWTPayload {
+  user_id: number;
+  username: string;
+  email: string;
+  role: 'admin' | 'user' | 'viewer';
+  permissions: string[];
+  exp: number;             // 过期时间戳
+  iat: number;             // 签发时间戳
+}
+```
+
+### 权限级别
+- **admin**: 所有操作权限
+- **user**: 可以创建、编辑、删除自己的编辑点
+- **viewer**: 只能查看编辑点
+
+### 权限检查中间件
+```python
+# FastAPI 示例
+from fastapi import Depends, HTTPException, status
+from fastapi.security import HTTPBearer
+
+security = HTTPBearer()
+
+async def verify_token(token: str = Depends(security)):
+    try:
+        payload = jwt.decode(token.credentials, SECRET_KEY, algorithms=["HS256"])
+        return payload
+    except jwt.ExpiredSignatureError:
+        raise HTTPException(
+            status_code=status.HTTP_401_UNAUTHORIZED,
+            detail="Token has expired"
+        )
+    except jwt.JWTError:
+        raise HTTPException(
+            status_code=status.HTTP_401_UNAUTHORIZED,
+            detail="Invalid token"
+        )
+
+async def check_edit_permission(
+    edit_point_id: str,
+    current_user: dict = Depends(verify_token)
+):
+    # 检查用户是否有权限编辑该编辑点
+    edit_point = await get_edit_point(edit_point_id)
+    if not edit_point:
+        raise HTTPException(status_code=404, detail="Edit point not found")
+    
+    if current_user["role"] != "admin" and edit_point.user_id != current_user["user_id"]:
+        raise HTTPException(status_code=403, detail="Permission denied")
+    
+    return edit_point
+```
+

+4. **读写分离**: 读操作使用只读副本
+
+### 缓存策略
+1. **Redis缓存**: 缓存热点数据和查询结果
+2. **CDN**: 静态资源使用CDN加速
+3. **应用缓存**: 内存中缓存频繁访问的数据
+
+### API优化
+1. **批量操作**: 支持批量创建、更新、删除
+2. **字段选择**: 支持指定返回字段减少数据传输
+3. **压缩**: 启用gzip压缩
+4. **限流**: 实现智能限流防止滥用
+
+## 🧪 测试策略
+
+### 单元测试
+```python
+import pytest
+from fastapi.testclient import TestClient
+
+def test_create_edit_point():
+    response = client.post("/video-edit/edit-points", json={
+        "video_id": "test-video",
+        "project_id": "test-project",
+        "position_x": 50.0,
+        "position_y": 30.0,
+        "timestamp": 15.5,
+        "description": "Test edit point"
+    })
+    assert response.status_code == 201
+    assert response.json()["successful"] == True
+```
