Additional Protocol Libraries

Introduction

Beyond the major streaming protocols, VASTreaming offers specialized protocol libraries that solve specific problems—ultra-low latency, local network production, next-generation transport, and legacy compatibility. Each targets a distinct use case where general-purpose protocols fall short.

NDI (Network Device Interface)

NDI is the standard for high-quality, low-latency video over local networks. It powers live production workflows—switching, mixing, and routing video between devices on the same LAN with virtually no delay.

VASTreaming's NDI library lets you send and receive NDI streams programmatically. Ideal for broadcast automation, virtual production, and multi-camera setups where every frame counts.

Capabilities:

• NDI source discovery and stream reception
• NDI stream publishing from any video/audio source
• Full-resolution, low-latency transport over standard Ethernet

WebTransport over QUIC

WebTransport over QUIC is the next evolution in real-time media delivery. Built on HTTP/3 and QUIC, it combines the low latency of UDP with the reliability and security of TLS—all through a single, multiplexed connection.

VASTreaming's WebTransport library enables ultra-low-latency streaming directly to modern browsers without plugins or WebRTC complexity. It supports both reliable and unreliable data channels, making it suitable for live video, real-time telemetry, and interactive media applications.

Capabilities:

• QUIC-based media transport with 200-300ms latency on LAN
• Reliable and unreliable data streams over a single connection
• Native browser support—no plugins or extensions required
• TLS 1.3 encryption by default

MJPEG over HTTP

MJPEG over HTTP delivers the lowest possible video latency at the cost of higher bandwidth and no audio channel. When frame-by-frame immediacy matters more than compression efficiency, MJPEG is the right tool. Client and server modes supported.

TS over HTTP

Transport Stream over HTTP provides simple, reliable streaming using the TS container over standard HTTP infrastructure. See the TS library page for full details. Client and server modes supported.

Custom PCM Streaming

For the absolute lowest audio latency, VASTreaming provides a custom PCM streaming protocol over WebSocket. A JavaScript client is included for browser-based playback. PCM streaming trades bandwidth for zero encoding delay—ideal for LAN-based audio monitoring, intercom systems, and real-time audio processing pipelines.

Platforms

Available for all major platforms (availability varies by protocol):

• C# / .NET: .NET 6/7/8/9/10+ (cross-platform), .NET Framework 4.5+
