LM-Monitor

LM-Monitor is a live video monitor for iPhone that receives two professional broadcast protocols: NDI® and SRT.

Use it to confirm video and audio arrival on set, in the control room, or during streaming rehearsals — without firing up a laptop or a dedicated monitor.

Highlights:

• Automatic discovery of NDI® sources on the local network, one tap to full-screen preview
• Distraction-free black-background monitoring with a toggleable source-name overlay
• SRT receive in Caller, Listener, and Rendezvous mode
• Passphrase, Stream ID, latency, and I-frame interval are all configurable
• Simultaneous AAC audio with mute toggle
• Protocol picker on launch — pick NDI® or SRT for the current job
• Built-in "Licenses" screen that lists every third-party component (HaishinKit.swift, libsrt, NDI® SDK) and its attribution

Use cases:

• Verifying that a camera or switcher feed has actually reached the venue or the cloud
• Mixed NDI® + SRT environments where one device should cover both
• Validating NDI® Bridge or contribution feeds traveling over the public internet
• Multi-camera rehearsal checks before doors open

LM-Monitor is an NDI® compatible application. NDI® is a registered trademark of Vizrt NDI AB. SRT is a protocol created, open-sourced, and maintained by Haivision Systems Inc. SRT support is implemented using HaishinKit.swift (BSD-3-Clause) and libsrt (Mozilla Public License 2.0). See the in-app "Licenses" screen for full attribution and source links.
