NTgCalls

NTgCalls is a lightweight open-source library for media streaming in Telegram calls. Built from scratch in C++ with WebRTC & Boost, it prioritizes accessibility to developers and resource efficiency.

Powerful	Simple	Light
Built from scratch in C++ using Boost and libwebrtc	Simple Python, Node.js, Rust, GO, C Bindings and Java for Android SDK	We removed anything that could burden the library, keeping every binding a thin layer over the same native core

Features

Pre-built binaries for macOS (arm64-v8a), Linux (x86_64, arm64-v8a), Windows (x86_64), and Android (x86, 86_64, arm64-v8a, armv7)
Call flexibility: Group and private call support
Media controls: pause/resume and mute/unmute
Codec compatibility: H.264, HEVC (H.265), VP8, VP9, AV1, AAC, MP3, Opus
Content sharing: Screen streaming, Microphone and Camera streaming
Pre-built wheels for Python, npm packages for Node.js, crates for Rust & AAR SDK library for Android

Installing

Prebuilt packages are published for every supported language, so most users never need to compile anything.

Language	Package	Install
Python	ntgcalls	`pip install ntgcalls`
Node.js	ntgcalls	`npm install ntgcalls`
Rust	ntgcalls	`cargo add ntgcalls`
Java (Android)	io.github.pytgcalls:ntgcalls	Gradle dependency
C, C++ and Go	Release archives	Download the shared or static zip

Building from source

Prerequisites are listed in the Build Guide. All commands are run from the root of the repository.

Target	Command	Output
Python	`python3 setup.py install`	Installed in the current environment
Node.js	`python3 setup.py build_lib --target=node`	`targets/node/build/Release/ntgcalls.node`
C and C++	`python3 setup.py build_lib`	`shared-output` and `static-output`

The C target builds both the shared and the static library in a single run. Each output directory also contains an include folder with the headers to add to your project.

The Rust bindings do not build the native library: the ntgcalls-sys build script downloads the matching static libraries from the GitHub release for your platform. Set NTGCALLS_RELEASE_BASE to build against a local release instead.

Using the library from Go

[!WARNING] Static linking for Windows is not supported yet since our library is built with MSVC and Go uses MinGW for static linking. More info can be found here

Go consumes the C bindings through an example project in ./examples/go/:

Download the shared or static release from the Releases page
Copy ntgcalls.h into ./examples/go/ntgcalls/
Copy the remaining files into ./examples/go/
- ntgcalls.dll or ntgcalls.lib on Windows amd64
- libntgcalls.so or libntgcalls.a on Linux amd64
- libntgcalls.dylib or libntgcalls.a on macOS
Run go build or go run . with CGO_ENABLED=1
- $env:CGO_ENABLED=1; go run . on Windows PowerShell
- CGO_ENABLED=1 go run . on UNIX
