ZLMediaKit
WebRTC/RTSP/RTMP/HTTP/HLS/HTTP-FLV/WebSocket
...The project is designed for protocol conversion, live streaming, low-latency playback, recording, forwarding, and large-scale client access. Its asynchronous, multithreaded network model makes it suitable for commercial streaming deployments with many concurrent connections. ZLMediaKit can be deployed directly as a complete media server or embedded through its standard C API as an SDK for other languages and systems. It also provides REST APIs and webhooks so businesses can integrate authentication, event handling, and custom streaming logic.
