    Casting an iPhone screen with NDI

    Hi,
    I haven't come across the info I'm looking for, maybe someone can help.
    I don't want to use the iPhone as a camera, I want to cast the screen to
    our 460 over NDI, is this possible? What needs to be put on the iPhone to
    Make this work?
    Thanks in advance.

    You have to use the AirPlay feature on the iPhone to get the screen sent out, then take that into a system that will turn it into NDI. There are two solutions I know about.

    The first is NewTek Connect Pro. It has AirPlay receiving built in. https://www.newtek.com/connect/connect-pro/

    The second method is to use NDI Scan Converter with an AirPlay receiving application like AirServer. I've documented this workflow here. http://kanelp7.wixsite.com/kanesworl...into-tricaster

    If you have Mac:
    0) install JustBroadcaster.com ($40)
    1) connect iPhone to Mac by data cable
    2) insert iPhone to JustBroadcaster
    3) turn on "NDI Output ON" in JustBroadcaster.

    example video how to iPhone--data cable-->JustBroadcaster--ndi-->vMix works.

    I just tried this method and it appeared to work.

    Install the NDI Mac Tools
    Connect iOS device via lightning cable to your Mac.
    Start QuickTime Player
    In the menu click File -> New Movie Recording
    A new window will open. Next to the red record button is a little down arrow. Click that and change the source to your iOS device
    Start the NDI Scan Converter. File -> QuickTime Player

    That should start the broadcast.
    I verified on the local machine (Be sure to mute source/receiver if you're on the same machine)

    ***EDIT***
    Alternatively you could of course just record the content you wish using QuickTime and then use whatever to broadcast the saved movie file. Instead of using Scan Converter. Not sure if this would ensure that the captured image isn't scaled down a bit to fit on the screen.

    I'm half developing an iOS app that captures the screen on device and broadcasts the NDI stream directly. Not sure how much demand there is for that solution. If you're interested in that please do let me know.
