Py3AMF is fork of PyAMF to support Python3

Why Py3AMF

By states of issues and PR in PyAMF, it dosen’t seems to be under developing. And another PR that supports Py3 has been discontinued for over two years. This is the only Python AMF Project which trying to support Py3 under developing on GitHub.


Pass test But, adapters were not tested


This project isn’t completed. If you want to make it fast, please send PR.


This was tested on Ubuntu 16.04.2 and macOS 10.12.4

To install, you can use pip3 on your environment.

pip3 install Py3AMF

Or, you can use to develop.

git clone
cd Py3AMF
# python3 test
python3 install

Simple example

Everything is same with PyAMF, but you have to concern str and bytes types.

import pyamf
from pyamf import remoting
from pyamf.flex import messaging
import uuid
import requests

msg = messaging.RemotingMessage(operation='retrieveUser',
req = remoting.Request(target='UserService', body=[msg])
ev = remoting.Envelope(pyamf.AMF3)
ev['/0'] = req

# Encode request
bin_msg = remoting.encode(ev)

# Send request; You can use other channels like RTMP
resp ='',
                     headers={'Content-Type': 'application/x-amf'})

# Decode response
resp_msg = remoting.decode(resp.content)


  • Check adapters

PyAMF provides Action Message Format (AMF) support for Python that is compatible with the Adobe Flash Player. It includes integration with Python web frameworks like Django, Pylons, Twisted, SQLAlchemy, web2py and more.

The Adobe Integrated Runtime and Adobe Flash Player use AMF to communicate between an application and a remote server. AMF encodes remote procedure calls (RPC) into a compact binary representation that can be transferred over HTTP/HTTPS or the RTMP/RTMPS protocol. Objects and data values are serialized into this binary format, which increases performance, allowing applications to load data up to 10 times faster than with text-based formats such as XML or SOAP.

AMF3, the default serialization for ActionScript 3.0, provides various advantages over AMF0, which is used for ActionScript 1.0 and 2.0. AMF3 sends data over the network more efficiently than AMF0. AMF3 supports sending int and uint objects as integers and supports data types that are available only in ActionScript 3.0, such as ByteArray, ArrayCollection, ObjectProxy and IExternalizable.
