No mature, production-ready, open-source, IP-exclusive multiviewer exists today.
MosaicTV is the closest but is unmaintained. For practical use, accept either a hybrid open-source tool (OBS) or a free proprietary one (NDI Studio Monitor).

This shifts the tool from just monitoring to intelligent visual orchestration — something usually found in high-end broadcast control rooms (e.g., Evertz, Imagine Communications), not open source. | Feature | Typical OSS Multiviewers | This
For engineers dealing with remote contributions (SRT - Secure Reliable Transport), standard multiviewers fail. SRT Multiviewer (community builds on GitHub) is exclusive because it refuses to handle anything except SRT streams. For engineers dealing with remote contributions (SRT -

The exclusivity of open source software comes at a cost: complex dependency hell. Unlike a Blackmagic hardware box that "just works," open source IP multiviewers require:
GStreamer is a pipeline-based multimedia framework. Building a multiviewer means writing a pipeline like compositor to mix video sinks.
