For the high-end broadcaster using SMPTE ST 2110, (developed by the BBC R&D and community) is an exclusive HTML5-based multiviewer. It utilizes WebRTC and WebAudio to de-packetize RTP flows directly in a browser. It is not a traditional grid, but it is the only open source tool that truly listens to separate video, audio, and ancillary essence flows.
Deploying an open-source software multiviewer requires careful hardware planning. Decoding multiple high-definition IP video streams simultaneously is computationally expensive. Hardware Acceleration (GPU Decoding)
While not fully open source (SDK is proprietary), the by Vizrt is often the first stop. It functions as a basic multiviewer, but it lacks advanced layouts.
An efficient software-based IP multiviewer performs four core tasks:
Through a VLM (VideoLAN Manager) configuration script, VLC can launch a single instance that listens to dozens of IP streams, scaling and positioning them into a unified display window.
Implement strict presentation timestamps (PTS). Use GStreamer's synchronization clock features ( GstClock ) to force the audio analysis filters and video rendering elements to evaluate data based on identical packet timestamps. 3. Resource Exhaustion and Thread Interlocking
You can launch multiple VLC instances via command line or use "VLC Mosaic" configurations (VLM) to combine streams into a single window. 🛠️ Key Open-Source Components for Custom Builds
Most tools are free to acquire, allowing budgets to be redirected toward hardware or specialized development.
