    NDI DAT

    Summary

    The NDI DAT lists in a table and monitors all NDI sources and streams found on the network. Callbacks are provided to trigger actions when sources are added/removed/changed and when streams start/stop.

    See NDI, NDI In TOP and NDI Out TOP.

    Parameters - Monitors Page

    Callbacks DAT callbacks - Script callbacks for events relating to NDI sources and streams.

    Extra Search IPs extraips - By default NDI searches using mDNS, which is usually limited to locate networks. To find sources available on machines not reachable by mDNS, this parameter can be filled with a space-separated list of one or more IP address.

    Persistence (ms) persistence - Persistence affects how long an entry in the DAT stays present even after the source has disappeared. This allows for a source to disappear for a bit and then reappear without being removed from the list.
