Windows Streaming Libraries

Introduction

VASTreaming's native Windows libraries are written in pure C++ for maximum performance and seamless integration into Visual Studio projects.

For C#/.NET development, see our .NET and MAUI libraries.

Client/Server

Streaming Server—single or multi-protocol server that scales from embedded devices to cloud deployments. Ingest, transcode, and redistribute streams across protocols.

Capture—camera and microphone with built-in encoding. Ready to publish to any supported protocol.

Playback—receive and decode live streams via any modern protocol. Off-screen mode for raw frame access and custom processing.

Protocols

RTMP—the standard for live stream ingestion. Publish to YouTube, Facebook, Twitch, and any RTMP-compatible CDN. Full client, publisher, and server support.

RTSP/RTP—low-latency streaming for IP cameras, surveillance, and VoIP. Publish, play, and serve. UDP, TCP interleaved, multicast, and RTSPS transport modes.

HLS—HTTP-based adaptive streaming. Client playback with multiple renditions.

WebRTC—sub-second browser-native streaming. Publishing and playback.

More Protocols—MJPEG over HTTP and other specialized protocols.

File Formats

MP4—advanced reader and writer with fragmented MP4, crash recovery, progressive download optimization, and live file tailing.

Transport Stream—read, write, multiplex, and stream TS data. Multicast, TS over HTTP, and RTP payload support.

Processing

Video Mixer—real-time compositing of live feeds, files, images, and text overlays. GPU-accelerated via OpenGL. Multi-resolution output for adaptive streaming.

Audio Mixer—multi-source audio mixing with per-source volume control. Built-in echo cancellation for two-way communication.

Codec—hardware-accelerated encoding/decoding via Media Foundation. FFmpeg integration for broader codec coverage.

Implementation

Written in pure C++ for maximum performance and direct integration into Visual Studio projects. The architecture is modular and extensible—custom streaming features and protocol-level extensions can be implemented to meet specific project requirements.
