NDI over Aruba Wireless

  • 1.  NDI over Aruba Wireless

    Posted Dec 13, 2020 07:59 PM
    I'm trying to set up a NDI camera for a livestream that we're doing using OBS.  I can use NDI over a wired network, but OBS can't see the NDI feed from our wireless camera.  I can take the cam to another network, and it works fine, so it's something specific to the Aruba AP's.  I've inherited this system, so I'm still not totally familiar with it.  Any help on how I can troubleshoot this would be greatly appreciated.  Thanks!

    From what I can see, NDI uses mDNS for the discovery between the camera and the PC. If the devices are in the same vlan (ip subnet), you can disable broadcast filtering as a quick workaround. Disabling broadcast filtering can result in overall performance degradation. The better solution is to enable and configure AirGroup to proxy the mDNS discovery packets and optionally filter them.

    Yes, creating an AirGroup is exactly what I want to do.  I saw references to it, and I've found instructions on every part of it but creating the service IDs for the AirGroup.  How do I find the specific strings for that service?  A quick search hasn't turned up any information on where the information for that comes from.  Thanks!

    Hi John,

    Did you ever solve your issue and find the specific strings for that service? I found one class service as  _ndi._tcp. so far.


    I am in the same exact boat with an NDI camera. 

    Thank you.

    No, not at this point, and it's weird because it worked a while back on an older revision of the firmware.  I hadn't thought about that because it's been a while.  At that point, I was able to do AllowAll, and it worked.  Now, that's not even letting it through, so something else must have changed.

    Well, I did figure something out recently on my issue, but not sure what it means.  I think part of what I was seeing with NDI was that I was going from an iPhone to a Mac originally.  That's when it worked before, and that still seems to work  Though, when I try to use NDI to or from Windows over the Aruba wireless, it doesn't work.  At least, it worked in testing.  I don't have a spare Mac that I can just put in for the Windows machine I'm using.  I'd love to figure out what's going on.

    I'm seeing a similar issues and have basically allowed every service in the aruba console but still can't get it working, we're going between an iPhone and a Windows device (actually a windows VM on an Android OS.... don't ask).​  The 2 devices are on the same SSID & vlan & subnet so by my understanding there should be no issues with mDNS but we can't get the 2 to talk.
    As a work around we have enabled the windows device to act as a hotspot and connected the phone to this and the NDI works perfectly.  Not an ideal configuration and would like to get this fixed

    Have you tried to disable the broadcast/multicast filtering? If it works then, you are not allowing all services (note that you may need to add services to allow everything, by default if you select all, it is just what is preconfigured).

    Yes, and it still doesn't work.  Unless you're going to a MacOS machine.  Whatever is going on, Macs and iOS devices can see the NDI signal through the Aruba IAPs, so it's just an issue with Windows not seeing it.  However, on a non-Aruba system, the Windows machine can see the NDI signal just fine as well.

    Hard to tell in that case what is the issue. Unless someone recognized the issue, best would be to open a support ticket.
