+
+## Project Overview
+
+RenderWorker is a Python-based video processing service that renders video content using FFmpeg. It operates as both a Flask web service and a standalone worker process, processing video rendering tasks with templates, effects, and various transformations.
+
+## Architecture
+
+The project uses a modern layered architecture with clear separation of concerns:
+
+### Core Components
+
+- **Services Layer** (`services/`): Main business logic with dependency injection
+  - `RenderService`: Handles video rendering operations
+  - `TemplateService`: Manages video templates and resources
+  - `TaskService`: Orchestrates the complete task lifecycle
+  
+- **Entity Layer** (`entity/`): Data models and domain logic
+  - `RenderTask`: Core data model for rendering tasks
+  - `FFmpegCommandBuilder`: Generates FFmpeg commands from tasks
+  - `effects/`: Pluggable effect processing system (zoom, speed, skip, tail, cameraShot)
+
+- **Configuration** (`config/`): Centralized configuration management
+  - Environment-based configuration with dataclasses
+  - FFmpeg, API, Storage, and Server configurations
+
+- **Utilities** (`util/`): Common utilities for API, OSS, FFmpeg operations
+
+### Entry Points
+
+- **Web Service**: `app.py` - Flask application serving HTTP endpoints
+- **Worker Process**: `index.py` - Long-running task processor that polls for work
+- **Legacy Compatibility**: Maintains backward compatibility with older `entity/ffmpeg.py` and `biz/` modules
+
+## Common Commands
+
+### Running the Application
+
+```bash
+# Web service mode (Flask API)
+python app.py
+
+# Worker mode (background task processor)  
+python index.py
+
+# Worker with template redownload
+python index.py redownload
+```
+
+### Development Setup
+
+```bash
+# Install dependencies
+pip install -r requirements.txt
+
+# Environment setup
+cp .env.example .env
+# Edit .env with your configuration
+```
+
+### Building
+
+```bash
+# Build standalone executable
+pyinstaller index.spec
+
+# Build updater
+pyinstaller updater_helper.spec
+```
+
+## Key Environment Variables
+
+Required configuration (see `.env.example`):
+- `API_ENDPOINT`: Backend API endpoint
+- `ACCESS_KEY`: Authentication key
+- `TEMPLATE_DIR`: Directory for template storage
+- `ENCODER_ARGS`: FFmpeg encoder arguments (default: "-c:v h264")
+- `VIDEO_ARGS`: Video processing arguments
+- `OTLP_ENDPOINT`: OpenTelemetry endpoint for monitoring
+
+## Architecture Patterns
+
+### Service Layer Pattern
+All new code should use the service layer:
+
+```python
+from services import DefaultRenderService, DefaultTemplateService, DefaultTaskService
+
+# Dependency injection
+render_service = DefaultRenderService()
+template_service = DefaultTemplateService()
+task_service = DefaultTaskService(render_service, template_service)
+
+# Process tasks
+success = task_service.process_task(task_info)
+```
+
+### Effect Processing System
+Video effects use a pluggable architecture:
+
+```python
+from entity.effects import registry
+from entity.effects.base import EffectProcessor
+
+# Get existing effect
+processor = registry.get_processor('zoom', '0,2.0,1.5')
+
+# Register new effect
+class MyEffect(EffectProcessor):
+    def validate_params(self) -> bool:
+        return True
+    
+    def generate_filter_args(self, video_input: str, effect_index: int):
+        return filter_args, output_stream
+        
+    def get_effect_name(self) -> str:
+        return "myeffect"
+
+registry.register('myeffect', MyEffect)
+```
+
+### Task Processing Flow
+
+1. **Task Reception**: API receives task via HTTP endpoint or polling
+2. **Template Resolution**: Template service downloads/loads video templates
+3. **Task Creation**: Task service creates RenderTask with effects and resources
+4. **Command Building**: FFmpegCommandBuilder generates FFmpeg commands
+5. **Execution**: RenderService executes FFmpeg with monitoring
+6. **Cleanup**: Temporary files cleaned, results uploaded
+
+## Backward Compatibility
+
+The codebase maintains compatibility with legacy components:
+- `biz.task.start_task()` - Main task entry point
+- `entity.ffmpeg.FfmpegTask` - Legacy task object (now simplified)
+- `template.get_template_def()` - Template access
+
+These should work but new development should use the service layer.
+
+## FFmpeg Integration
+
+The system generates complex FFmpeg commands for video processing:
+- Supports effects chaining (zoom, speed changes, cropping)
+- Handles multiple input files and concatenation
+- Manages audio processing and overlays
+- Supports LUT color grading and subtitle embedding
+
+## Monitoring and Telemetry
+
+- **OpenTelemetry**: Distributed tracing for request monitoring
+- **Structured Logging**: Detailed logs for debugging
+- **Error Handling**: Custom exception types (`RenderError`, `FFmpegError`, `TemplateError`)
+
+## File Organization
+
+- Configuration and environment variables → `config/`
+- Business logic and services → `services/`
+- Data models and domain objects → `entity/`
+- HTTP API and external integrations → `util/`
+- Legacy compatibility layer → `biz/`
+- Application entry points → `app.py`, `index.py`
+
+## Working with Templates
+
+Templates define video processing workflows:
+- Downloaded from remote API and cached locally
+- Support video parts, effects, overlays, and audio
+- Use placeholder system for dynamic content
+- Managed by `TemplateService` with automatic updates
+
+## Development Notes
+
+- The project recently underwent major architectural refactoring from monolithic to layered design
+- New features should use the services layer and effect processor system
+- Legacy code is maintained for compatibility but simplified
+- All video processing ultimately uses FFmpeg with generated command lines
+- The system supports both synchronous (web) and asynchronous (worker) operation modes

+
+## 快速开始
+
+### 1. 安装测试依赖
+
+```bash

+```
+
+### 2. 运行测试
+
+使用测试运行器脚本：
+
+```bash
+# 运行所有测试
+python run_tests.py all --coverage
+
+# 只运行单元测试
+python run_tests.py unit --coverage --html-report
+
+# 只运行集成测试
+python run_tests.py integration
+
+# 运行特定特效测试
+python run_tests.py effects --effect zoom
+
+# 运行压力测试
+python run_tests.py stress
+```
+
+或直接使用 pytest：
+
+```bash
+# 运行所有测试
+pytest tests/ -v --cov=entity --cov=services
+
+# 只运行单元测试
+pytest tests/test_effects/ tests/test_ffmpeg_builder/ -v
+
+# 只运行集成测试
+pytest tests/test_integration/ -v -m integration
+
+# 生成覆盖率报告

+
+## 测试类型说明

+
+### 环境变量
+

+
+## 特效测试详解
+
+### 缩放特效 (ZoomEffect)
+
+测试用例：
+- 有效参数验证：`"0,2.0,3.0"`（开始时间，缩放因子，持续时间）
+- 无效参数处理：负值、非数字、参数不足
+- 静态缩放：持续时间为 0
+- 动态缩放：指定时间段内的缩放
+- 位置 JSON 解析：自定义缩放中心点
+
+生成滤镜格式：
+```
+# 静态缩放
+[0:v]trim=start=0,zoompan=z=2.0:x=iw/2:y=ih/2:d=1[v_eff1]
+
+# 动态缩放
+[0:v]zoompan=z=if(between(t\,0\,3.0)\,2.0\,1):x=iw/2:y=ih/2:d=1[v_eff1]
+```
+
+### 变速特效 (SpeedEffect)
+
+测试用例：
+- 加速效果：`"2.0"`（2倍速）
+- 减速效果：`"0.5"`（0.5倍速）
+- 无效参数：零值、负值、非数字
+- 默认处理：空参数或 1.0 倍速
+
+生成滤镜格式：
+```
+[0:v]setpts=2.0*PTS[v_eff1]
+```
+
+## FFmpeg 命令构建测试
+
+### 测试场景
+
+1. **单文件复制**：直接复制无需编码
+2. **多文件拼接**：使用 concat 滤镜
+3. **特效处理**：复杂滤镜链构建
+4. **错误处理**：缺失文件、无效参数
+
+### 命令验证
+
+使用 `FFmpegValidator` 验证：
+- 命令结构完整性
+- 输入输出文件存在
+- 滤镜语法正确性
+- 流标识符格式
+
+## 集成测试详解
+
+### 真实 FFmpeg 执行
+
+测试流程：
+1. 创建测试视频文件
+2. 构建 FFmpeg 命令
+3. 执行命令并检查返回码
+4. 验证输出文件存在且有效
+
+### 测试用例
+
+- 简单复制操作
+- 单特效处理
+- 多特效组合
+- 视频拼接
+- 错误情况处理
+
+### 性能测试
+
+监控指标：
+- 执行时间
+- 内存使用
+- 文件大小
+- 处理速度
+
+## 代码覆盖率
+
+目标覆盖率：≥ 70%
+
+覆盖范围：
+- `entity/` 目录下的所有模块
+- `services/` 目录下的所有模块
+
+报告格式：
+- XML 格式：用于 Jenkins CI/CD
+- HTML 格式：用于本地查看
+- 终端输出：实时查看缺失覆盖
+
+## CI/CD 集成
+
+### Jenkins Pipeline
+
+配置文件：`Jenkinsfile`
+
+阶段：
+1. 环境准备
+2. 代码质量检查
+3. 单元测试
+4. 集成测试
+5. 完整测试套件
+6. 性能测试
+
+报告生成：
+- JUnit XML 测试报告
+- Cobertura 覆盖率报告
+- HTML 测试和覆盖率报告
+
+### 自动化触发
+
+- 代码提交时运行单元测试
+- PR 创建时运行完整测试
+- 主分支更新时运行包含性能测试的完整套件
+
+## 故障排除
+
+### 常见问题
+
+1. **FFmpeg 未找到**
+   ```bash
+   # 安装 FFmpeg
+   sudo apt-get install ffmpeg  # Ubuntu/Debian
+   brew install ffmpeg          # macOS
+   ```
+
+2. **测试视频创建失败**
+   ```bash
+   # 手动创建测试视频
+   python run_tests.py setup
+   ```
+
+3. **覆盖率过低**
+   - 检查是否有未测试的代码路径
+   - 添加边界条件测试
+   - 验证测试是否实际运行
+
+4. **集成测试超时**
+   - 增加超时时间：`--timeout=600`
+   - 使用更小的测试文件
+   - 检查系统资源使用情况
+
+### 调试技巧
+
+1. **查看详细输出**：
+   ```bash
+   pytest tests/ -v -s
+   ```
+
+2. **只运行失败的测试**：
+   ```bash
+   pytest tests/ --lf
+   ```
+
+3. **停在第一个失败**：
+   ```bash
+   pytest tests/ -x
+   ```
+
+4. **查看覆盖率详情**：
+   ```bash
+   pytest tests/ --cov=entity --cov-report=term-missing
+   ```
+
+## 贡献指南
+
+### 添加新测试
+
+1. 在相应目录创建测试文件
+2. 使用描述性的测试函数名
+3. 添加适当的测试标记
+4. 更新文档说明
+
+### 测试最佳实践
+
+1. **独立性**：每个测试应该独立运行
+2. **可重复性**：测试结果应该一致
+3. **清晰性**：测试意图应该明确
+4. **完整性**：覆盖正常和异常情况
+
+### 代码质量
+
+- 遵循 PEP 8 代码风格
+- 使用类型注解
+- 添加适当的文档字符串
+- 使用有意义的变量名
