Broadcasting & Live Streaming SDK for .NET
Build professional live streaming and broadcasting applications with VisioForge SDKs. Stream to YouTube, Facebook, and custom RTMP servers. HLS adaptive streaming, SRT low-latency transport, NDI network video, DeckLink hardware output — all from C# and .NET.
Broadcasting Development Challenges
Multi-Platform Streaming
Delivering live video to YouTube, Facebook, custom RTMP servers, and HLS endpoints simultaneously requires managing multiple output protocols and encoding pipelines.
Low-Latency Requirements
Professional broadcasting demands sub-second latency for live production, real-time monitoring, and audience interaction — standard HTTP streaming adds unacceptable delay.
Encoding Complexity
Configuring H.264/H.265 encoders with proper GOP size, bitrate control, and keyframe intervals for each streaming platform while maintaining quality and performance.
Hardware Integration
Integrating professional broadcast hardware like Blackmagic DeckLink cards and NDI sources/outputs requires specialized SDI/HDMI pipeline handling.
How VisioForge SDKs Solve These Challenges
VisioForge Media Blocks SDK provides dedicated sink blocks for every major streaming protocol. Build pipelines that encode once and output to multiple destinations simultaneously — YouTube, Facebook, HLS, SRT, NDI, and DeckLink — with a consistent API across platforms.
- YouTubeSinkBlock and FacebookLiveSinkBlock for one-line platform streaming
- HLSSinkBlock with built-in HTTP server for adaptive streaming
- SRT transport for low-latency, reliable streaming over lossy networks
- NDI sink/source blocks for IP-based studio production workflows
- DeckLink output blocks for professional SDI/HDMI broadcast hardware
- Tee blocks enable simultaneous preview, recording, and streaming from a single source
Key Broadcasting Features
YouTube & Facebook Live
Stream directly to YouTube and Facebook Live using your streaming key. H.264 + AAC encoding with configurable quality settings.
HLS Adaptive Streaming
Generate HLS playlists with configurable segment duration, playlist length, and built-in HTTP server. Ready for CDN distribution.
SRT Low-Latency Streaming
Secure Reliable Transport (SRT) for low-latency streaming over unpredictable networks. MPEG-TS encapsulation with H.264/H.265 support.
NDI Network Video
Send and receive video over IP networks using NDI protocol. Zero-configuration discovery for studio production environments.
DeckLink Hardware Output
Output to Blackmagic DeckLink cards for professional SDI/HDMI broadcast. Support for fill-key, multi-output, and HD/4K modes.
RTSP Server & Restreaming
Create RTSP servers to restream any source. Receive RTSP input, add overlays or processing, and re-publish to new endpoints.

C#Pipeline Architecture
VisioForge Media Blocks SDK uses a modular pipeline architecture. Each block handles one task — source, encode, mux, stream — and blocks connect together to form complete broadcasting workflows.
