Overview

The VASTreaming libraries provide a comprehensive .NET and C++ framework for building professional media streaming applications. Whether you need to capture video from cameras, stream content over RTSP/RTMP/HLS, transcode between formats, or build a complete multi-protocol streaming server, VASTreaming offers the tools to accomplish these tasks with minimal code and maximum performance.

What You Can Build

With VASTreaming libraries, developers can create:

Streaming Servers - Multi-protocol servers supporting RTSP, RTMP, SRT, HLS, MPEG-DASH, WebRTC and WebTransport simultaneously
Media Players - Custom video players with support for various streaming protocols and codecs
IP Camera Integrations - Connect to and manage IP cameras via RTSP and ONVIF protocols
Recording Solutions - Record live streams to MP4, transport stream, or other container formats
Transcoding Pipelines - Convert between codecs and formats with hardware acceleration support
Live Broadcasting - Capture from cameras, screens, or applications and broadcast to streaming platforms
Video Conferencing - Low-latency two-way communication using WebRTC

Key Features

Cross-Platform - Supports Windows, Linux, macOS, Android, and iOS
Multiple Protocols - RTSP, RTMP, SRT, HLS, LL-HLS, MPEG-DASH, WebRTC, WebTransport, multicast UDP
Extensive Codec Support - H.264, H.265/HEVC, AAC, MP3, Opus, and many more
Hardware Acceleration - Leverage NVIDIA CUDA, Intel Quick Sync, and platform-native APIs
Low Latency - Optimized for real-time streaming with typical latencies of 200-300ms on LAN, down to under 100ms in special cases
High Performance - Handle thousands of concurrent connections on server applications
Easy Integration - Clean API design with comprehensive documentation and samples

Getting Started

If you are new to VASTreaming, we recommend reading the documentation in the following order:

Terminology - Familiarize yourself with common terms and abbreviations used throughout the documentation
Supported Platforms - Understand which platforms and .NET versions are supported
List of Libraries - Learn about the available assemblies and their purposes
Basic Principles - Understand the source/sink architecture and data flow concepts
Core Primitives - Deep dive into the fundamental interfaces and classes

Quick Example

Here is a simple example that demonstrates recording from an RTSP camera to an MP4 file:

// Create a source from an RTSP camera
var source = VAST.Media.SourceFactory.Create("rtsp://camera-ip/stream");

// Create an MP4 sink for file writing
var sink = VAST.Media.SinkFactory.Create("/path/to/file.mp4");

// Use MediaSession to connect source to sink
var session = new VAST.Media.MediaSession();
session.AddSource(source);
session.AddSink(sink);

// Start streaming and recording
session.Start();
