SmolRTSP is a simple RTSP 1.0 server library tailored for embedded devices, such as IP cameras. It supports both TCP and UDP, allows any payload format, and provides a convenient and flexible API.
- Small. SmolRTSP is designed for use in embedded systems (e.g., IP cameras).
- Unopinionated. You can use SmolRTSP with bare POSIX sockets, libevent, or any other network framework.
- Zero-copy. SmolRTSP does not allocate or copy data while parsing.
- Battle-tested. SmolRTSP is used by Majestic, an IP camera streamer developed by OpenIPC.
- Supported protocols:
- Supported RTP payload formats:

A simple example server that streams H.264 video and G.711 Mu-Law audio can be found at examples/server.c
.
Run it as follows:
$ mkdir examples/build
$ cd examples/build
$ cmake .. && cmake --build .
$ sudo ./server
Then open a new terminal window to start playing:
$ ffplay rtsp:https://localhost
SmolRTSP is agnostic to a network backend: you can run it atop of any network/event loop framework. Currently, we support the following integrations:
Feel free to extend this list with your own integration code.
