A pure Python 3 RTMP server.

Project description


Latest version released on PyPi

This repo is part of self-host video streaming project.

No major new function designated for RTMP server will be introduced. However, bugs will still be fixed and features required by the self-host video streaming project will still be developed. Link to the repo created by original author.

Upgrade from the original repo

This repo aims to upgrade the original repo from Python 2 to Python 3, as well as integrate into my self-host video streaming project. Therefore, only and its dependencies will be modified in this repo.

Why am I doing this

I am working on a self-host video streaming project with Python 3 and Flask, hence, I need a Python 3 RTMP server. However, most of the Python RTMP solution do not match what I need (developed using Python 2, no longer maintained etc.), so, I decided to transit a Python 2 solution to Python 3.


This repo has three branches including master, dev and svs (self-host streaming).

  • master: release branch; stable
  • dev: development branch; maybe buggy or even can't run at all
  • svs: customized branch for self-host video streaming project

RTMP server

The main program is Please see the embedded documentation in that file. Some parts of the documentation are copied here. Other modules such as amf, util and multitask are used from elsewhere and contain their respective copyright notices.


Instead of looking at the documentation from the source code, I migrated (or migrating) the embedded documentation from the source code to Wiki of this repo.

Getting Started

Dependencies: Python 3.6+

Tested environment:

  • Windows 10 1803 with Python 3.8.3rc1
  • Ubuntu 18.04.4 LTS with Python 3.6.9.

First, clone all source files from this repo or install rtmplite3 from pip:

# Download from this repo
git clone

# Install from pip
pip install rtmplite3

There are multiple methods for you to run the RTMP server directly

  1. If you install the latest version (0.2.5) from pip, you can now start the RTMP server with the following methods:
$ rtmplite3 -d #or
$ python -m rtmplite3 -d
  1. Typically, an application can launch this server as follows if you clone this repo instead of install from pip:
$ python -d

The -d option enables debug trace so you know what is happening in the server.

There is also a -v option which enables verbose mode so you know all data sent and received in Hex. Please note that verbose mode will hugely affect the performance of the RTMP server

To know the command line options use the -h option:

$ python -h

For your convenience, this repo also provide you a single executable. You may want to check out our release page.

  1. And here is how to use the executable
# in Linux
$ chmod +x rtmp-Linux
$ ./rtmp-Linux

:: in Windows
> rtmp-Windows.exe
or double click the file

Known issues

  1. The program cannot exit with Control+C in Windows
  2. Viewer cannot join the stream after the feed started to broadcast
  3. recording and verbose mode will not enable when run with direct command and run as Python module
