Announcing TK Dynamic Delay v1.0

TK Dynamic Delay v1.0 brings dynamic buffer control (0–180s), a web dashboard, REST API, Windows services, and an MSI installer for Twitch streamers.

We’re excited to announce the first stable release of TK Dynamic Delay — a production-ready buffer and replay system for OBS Studio that enables Twitch streamers to capture and replay past moments during live streaming.

What’s in v1.0?

Live + Buffered Streaming

Stream live to Twitch while simultaneously building a delayed buffer in the background. The system uses OBS’s Multiple Output plugin to send an SRT copy to a local MediaMTX server, which creates HLS segments for buffering.

Dynamic Buffer Control

Adjust the buffer depth from 0 to 180 seconds in real-time using the web dashboard slider or preset buttons. Changes apply within 4–6 seconds.

Web Dashboard

An intuitive browser-based control interface at http://localhost:8080 with:

• Real-time status updates every 2 seconds
• Delay slider with instant feedback
• Quick preset buttons (30s, 60s, 90s, 120s, 180s)
• Buffer visualization and service status indicators

REST API

Full programmatic control via REST endpoints — perfect for StreamDeck integration:

POST /api/delay/set        {"delay": 60}
POST /api/delay/preset/30s
GET  /api/delay/current
GET  /api/status

Windows Services

Two Windows services (StreamDelayController and StreamDelayInput) auto-start on boot and run in the background. No manual process management required.

MSI Installer

A professional Windows installer built with WiX Toolset handles service registration, file placement, and Start Menu shortcuts. Silent installation supported.

System Requirements

• Windows 11 23H2+
• OBS Studio 28.0+ with Multiple Output plugin
• 4 GB RAM minimum (8 GB recommended)
• Localhost ports: 8080, 8888, 9000, 9997
