SRT Gateway for
Live Broadcast Contribution
Route, transcode, and distribute live streams with automatic failover and sub-50ms switchover. Already running 40+ routes 24/7 in sports broadcast. Now open to 30 pilot teams.
The Flow
Three stages. Deterministic. Predictable.
Process
Optional transcoding with FFmpeg. Audio matrix routing for complex channel mapping (7.1→stereo). Format conversion. Or zero-copy passthrough when processing isn't needed.
Video Stream Failover
Multi-input redundancy with automatic switchover under 50ms.
Sub-50ms Switchover
UDP selector switches between inputs at the frame level. Downstream decoders stay locked.
Auto-Failover
Up to 8 redundant inputs per route. Detects signal loss and switches automatically. Manual override available.
Hot-Add Inputs & Outputs
Add or remove sources and destinations while streaming. No route restart, no interruption to the live feed.
Mixed Protocols
Combine SRT, RTMP, HTTP sources in one failover group. Each with independent settings.
Video Routing Features
Infrastructure-grade reliability for live broadcasting.
Crash Recovery
Server restarts? No problem. Automatic process adoption rebuilds all routes from running processes. Zero manual intervention.
Hardware Transcode
VAAPI and Intel QSV for H.264 and HEVC/H.265. Auto-fallback QSV→VAAPI on Linux. 10x faster than CPU at a fraction of the power.
Zero-Copy Distribution
Internal multicast routing means adding outputs costs zero CPU. Route one stream to 50 destinations with the same overhead as one.
Hot Management
Add, remove, enable, disable, move outputs—all while streams are live. No route restart required. Zero interruption to other outputs.
VMAF Quality Analysis
Automated video quality scoring (VMAF 0-100, PSNR) on every active route. One-click quality check with full history and trends.
Prometheus & Grafana
Full /metrics endpoint: bandwidth, connections, CPU/RAM per process, Intel QSV GPU load. Pre-built Grafana dashboards included.
Diagram View
Interactive route visualization (inputs→outputs) built with React Flow. Real-time stats overlay without slowing down, even at scale.
Audio Matrix
Complex channel routing. Downmix 7.1→stereo. Extract specific channels. Per-channel gain control. Mix multiple sources.
Docker & Kubernetes
Containerized deployment with K8s orchestration and Terraform infrastructure-as-code. PostgreSQL support for multi-instance production.
REST API
Full CRUD on routes, inputs, outputs. JWT authentication. OpenAPI documentation. Automate everything, integrate anywhere.
SRT, RTMP, NDI, ST 2110 Protocol Support
Native protocol conversion. IP streams to NDI and ST 2110.

Live Stream Routing Use Cases
From field contribution to studio distribution.
Live Broadcast
Contribution feeds from field to studio. SRT bonding for mobile reporters. Automatic failover between primary and backup. Real-time quality monitoring.
Live Events
Multi-camera routing for concerts, sports, conferences. Fan-out to broadcast, web, social simultaneously. Add destinations on the fly as needs change.
OTT / Streaming
Ingest from any source, transcode with hardware acceleration, distribute via HLS or TS over HTTP. Built-in HLS player with latency indicator.
Remote Production
SRTLA bonding for unreliable networks. Works with BELABOX and mobile encoders. Starlink-ready. Automatic failover keeps the feed alive.
In Production
Teams running Vajra Cast in broadcast environments.
"We run 40+ routes 24/7. Hardware transcoding dropped our server costs by 60%. The visual routing diagram makes training new ops trivial."
"We handle live contribution across US, Europe and Asia. The multi-input failover saved our broadcast twice already. Reliable and cost-effective."
