  • 双传输模式支持：
    • RTP over UDP（标准模式）
    • RTP over TCP（适用于受限网络环境）
  • 智能会话管理：自动处理 RTSP 会话生命周期，包括超时重连和资源清理
  • 时区兼容性：新增完整的时区处理模块，支持 IPTV 时移回看功能
  • 应用场景：
    • 将 IPTV RTSP 时移源转换为 HTTP 流进行回看
    • 将家庭网络摄像机的 RTSP 流转换为 HTTP 流，方便在 IPTV 播放器中观看
    • 统一各类流媒体源到 HTTP 协议

⚡ 性能优化与现代化

  • 优化编译标志：新增 -O3 优化选项支持，显著提升运行效率
  • 缓冲区管理：引入 buffer_config.h 统一管理各类缓冲区配置

v2.0.0 is a milestone release with a comprehensive architecture refactoring and major feature updates. Compared to v1.1.1, this version represents a quantum leap — adding RTSP protocol support, introducing a modern testing framework, significantly optimizing performance, and enhancing code quality and maintainability.

AI played a crucial role in the development of this project.

🎯 Major New Features

🌟 RTSP Stream Support (Core Feature)

The highlight of v2.0.0 is the complete implementation of the RTSP/RTP protocol stack, making rtp2httpd a true multi-protocol streaming media gateway:

  • Complete RTSP client implementation: supports standard RTSP methods including DESCRIBE, SETUP, PLAY, TEARDOWN
  • Dual transport mode support:
    • RTP over UDP (standard mode)
    • RTP over TCP (for restricted network environments)
  • Intelligent session management: automatic RTSP session lifecycle handling, including timeout reconnection and resource cleanup
  • Timezone compatibility: new timezone processing module supporting IPTV time-shifted playback
  • Use cases:
    • Convert IPTV RTSP time-shifted sources to HTTP streams for catchup playback
    • Convert home IP camera RTSP streams to HTTP streams for viewing in IPTV players
    • Unify various streaming sources to HTTP protocol

⚡ Performance Optimization & Modernization

  • Optimized compiler flags: added -O3 optimization support for significantly improved runtime efficiency
  • Buffer management: introduced buffer_config.h for unified buffer configuration
  • Memory optimization: refactored data structures to reduce memory usage and fragmentation
  • Network optimization:
    • Enabled TCP_NODELAY for lower latency
    • Optimized multicast binding logic for improved stability

🧪 Testing & Quality Assurance

Established a comprehensive automated testing system, significantly improving code quality.
