Telegram VoIP Library for Python

Community | Documentation

PytgVoIP is a Telegram VoIP library written in Python and C++.

It uses libtgvoip (a library used in official clients) for voice encoding and transmission, and pybind11 for simple generation of Python extension written in C++.

It is targeted to MTProto client library developers, detailed usage guide is available here.

An example of usage with Pyrogram is available here (pytgvoip_pyrogram in PyPI), could be used as reference.

Hopefully this module support will be integrated in Pyrogram itself, also @cher-nov has plans to integrate it into Telethon as well

Features

• Python callbacks for sending and receiving audio stream frames allow flexible control
• Pre-built Windows wheels in PyPI

Requirements

• Python 3.5 or higher

Linux, MacOS: (use binary wheels from PyPI for Windows)

• libtgvoip
• CMake, C++11-compatible compiler, Python headers

Installing

pip3 install pytgvoip

Install pytgvoip_pyrogram to use this module with Pyrogram.

Encoding audio streams

Streams consumed by libtgvoip should be encoded in 16-bit signed PCM audio.

$ ffmpeg -i input.mp3 -f s16le -ac 1 -ar 48000 -acodec pcm_s16le input.raw  # encode
$ ffmpeg -f s16le -ac 1 -ar 48000 -acodec pcm_s16le -i output.raw output.mp3  # decode
