NDI — NewTek NDI

NDI is the de-facto standard for video over the local network — plug-and-play, auto-discovered. Phrame ingests NDI sources and publishes discoverable NDI outputs, so it drops straight into an NDI-based facility.

• Library: libphramendi.so (+ runtime libndi.so*) · Implementation: C++
• Direction: read (receive) and write (send)

Configuration

{
  "ndi": {
    "adapters": { "allowed": ["10.28.2.10", "10.28.2.11"] },
    "networks": { "discovery": "172.25.0.254" },
    "unicast": {
      "send": { "enable": true },
      "recv": { "enable": true }
    }
  }
}

• adapters.allowed — restrict to specific local NICs.
• networks.discovery — discovery server address.
• unicast.send / unicast.recv — enable unicast send/receive.

Source / output names are typically supplied by the host config (e.g. output-processor’s url: ndi://0.0.0.0/Name). NDI discovery relies on mDNS/avahi being available in the container.

Notes

NDI discovery uses mDNS, so sources appear only where multicast reaches. On a segmented network, name the source explicitly rather than relying on discovery.
