## What it is
ZLMediaKit is a high-performance, enterprise-grade streaming media server framework written in C++11, supporting RTSP, RTMP, HLS, HTTP-FLV, WebRTC, GB28181, SRT and more with protocol conversion between them. It ships both a ready-to-deploy MediaServer application and a C API SDK for building custom streaming solutions across Linux, macOS, Windows, iOS, and Android.

## Use cases
- run a self-hosted live streaming server supporting RTMP and HLS
- convert RTSP camera streams to WebRTC for low-latency browser playback
- build a GB28181 video surveillance platform
- serve HTTP-FLV streams to thousands of concurrent viewers
- embed streaming media capabilities into a C++ application via SDK
- bridge IP camera RTSP feeds into a web-based live platform
- record live streams to MP4 files
- set up an SRT ingest server for remote production

## When to choose
- you need a production-proven media server with many protocols and protocol conversion
- you need very low latency streaming (100-500ms) at high concurrency
- you need GB28181 or video surveillance protocol support
- you want a C API SDK to embed streaming into your own application
- you need cross-platform deployment including embedded/ARM devices

## When to avoid
- you only need simple VOD file serving rather than live streaming
- you prefer a managed cloud streaming service over self-hosting
- you need a pure client-side player library rather than a server
- your team cannot work with C++ or license terms (custom NOASSERTION license)
