While high-end professional IP multiviewers are often proprietary, there are several open-source and free software options that provide flexible monitoring for IP streams. Open-Source Options
OTT-Multiview: A web-based multiview screen specifically for HLS and MPEG-DASH streams. It is built on hls.js and Shaka Player, allowing you to create a mosaic of OTT feeds directly in a browser .
OBS Studio: While primarily for streaming, its "Multiview" feature (found under the View menu) is a powerful, free way to monitor multiple IP sources (like SRT, RTMP, or NDI) in a single grid .
MotionEyeOS: An open-source OS for the Raspberry Pi that specializes in monitoring multiple IP security cameras in a grid layout. It is widely used for self-hosted surveillance setups . Free & Specialized Versions ip multiviewer software open source exclusive
JMultiViewer Free: A free version of professional software designed for small production teams. It supports up to 4 channels and can monitor NDI, SDI, and IP sources for signal loss or frozen frames .
MultiViewer for F1: A community-driven, specialized app that lets you view multiple live streams (timing, driver cams, main feed) simultaneously. While niche, it is a leading example of "exclusive" multiviewer software for specific content . Key Features to Look For
When selecting an IP multiviewer, consider these technical requirements found in professional-grade tools like Stirlitz Media or TAG Video Systems: Community & Contribution
Protocol Support: Ensure it handles UDP, RTP, SRT, NDI, and HLS .
Alarms: Visual or email alerts for "black" or "frozen" frames .
Hardware Acceleration: GPU decoding (NVIDIA) is often required to monitor many 4K or HD streams at once without taxing the CPU . GitHub: Report issues, fork, and submit PRs
Any free multiviewer software for web video? : r/VIDEOENGINEERING
Here’s a feature concept for an open-source IP multiviewer software with an “exclusive” angle—meaning a capability not commonly found in free tools (or even some paid ones), designed to give your project a competitive edge.
