Containing NDI in dedicated VLANs

Par agrosjea
Hello everyone,

With NDI 3.8

We are encountering on several projects an issue that can't be solved without Newtek's insight.
We work on multimedia installations that include many feeds : Dante audio, DMX, sensors... and are used to defining one VLAN per type of feed in order to manage our broadcast domains properly.

The following drawing shows a typical configuration that we use (note that we have most of the time 1x 10Gb adapter dedicated to NDI)

We do want to contain NDI in its own VLAN. This is for a reason : We do not want NDI automatic load-balance to take 100% of the Audio or ArtNET link, leaving nothing behind...
The general question is : how can we control NDI so that it will only use the adapters that we specify (as Dante does) ?

What we already tried :

- We already asked NewTek's support about this and they indicated that access manager could help... but it looks like this tool is not meant for that.
- We tried to understand how the network adapter is elected by playing with the metrics and other type of parameter... no way to understand clearly and that only solves partially the problem.
- We wrote ACL in our switches :
- first version was pretty drastic and was to deny NDI feeds (UDP 5960-5970) on any VLAN other than NDI. It turned to NDI receivers not receiving the feeds anymore : the teaming algorithm seems not resilient enough to consider using an alternate network interface if the connection fails on the selected interface. With these ACL enabled : only the machines that (for an unknown reason) slected the NDI NIC by "default" could receive the feeds.
- we also worked on the discovery itself by denying mDNS on all VLANs except NDI. In this situation, a tool like NDI Analysis tool now clearly lists only IPs in the NDI subnet. But when we do connect the feeds, the "magic" behind NDI makes the feed going again through any of the other VLAN that the sender and receiver have in common... Moreover, no way for us to disable mDNS as a long term solution...

We would like to know :
- For a sender/receiver, is there a secret menu/config-file/network-adapter-naming-convention to tell NDI SDK not to use one or several Network Adapters ?
- If not, is there an official recipe for ACL that we could apply to our network so that NDI is contained in one single VLAN without creating side-effects?
- Could someone share detail about how a complete NDI handshake works (ex : sequence diagram) ? We could maybe have a better understanding of where the sender and receiver agrees on a specific network link to transport a feed ?

Previous verison of Tools still available?

Par SJ_TC_User
Is there any place to download an older version of NDI Tools? I see that the latest version of Scan Converter won't work or even install on a Windows 7 pc. Thanks!

NDI to 12G OpenGear Card?

Par simond83
Does anyone make one? And vice versa, 12G to NDI?

There's a lot of boxes that do this, but i'd really like an OpenGear interface.

NDI 4.0 and Panasonic HN-130 cameras

Par DStoneburner
I'm running NDI 3.8 on my TC 8000 and have no issues with my new Pansonic HN-130 cameras. If I update the NDI tools to 4, will that cause issues with my cameras? Just wondering if I have to wait for Panasonic to make a firmware update for compatibility. Thanks.

Scan Converter crashing!!

Par JCorreia
Hello,
Recently I've got some problems with the scan converter because it only stays up like 5 seconds and then it shuts automatically with no error or crash note. I've done some research but it seems like no one is having the same issue, at least on Windows machines but I've seen some posts about it on mac.
Any suggestion?


BTW I'm using windows 10 version 1903.

Recommended network topology

Par Meekel
What's the recommended network topology for NDI nowadays? We initially set our network up in a star topology, with our 2 x VMC1 on our core switch, with 20Gb connectivity to each node switch where we would have various other devices plugged in.

We believe it made sense at the time as almost all traffic was going to the VMC1's on the core switch.

I'm now wondering whether it's worth stacking our switches in a ring topology instead?

audio dropping out since NDI4...

Par rokestah
I have a TC410 all latest updates and AE3.
I have scan converter running on a pc and need to grab the desktop and audio for a broadcast on Monday but the audio is intermittent.
Been doing this for 2 years without issue and now this.

Why do I need to be a computer engineer to get all this stuff to work?

This happens from any pc with scan converter on to my TC410.
Works fine in studio monitor on any pc on our university network.

any ideas? don't wanna run cables when NDI is supposed to do this...

NDI Tools 4 Access Manager

Par SteveSpaw
We are unable to enter an IP address for remote source in any NDI tools 4 PC.
It worked perfect in 3.8 before upgrades.
If there was a previous address I can edit it, but I cannot create new entries.

This is a big deal.

Help? :question::question::question::stumped:

NDI 4 tools on Windows Server 2012 - missing DLL?

Par roddyp
I've got NDI 4 Tools installed on a Windows Server 2012 system, and when I try to start Test Patterns I get a series of three popups saying

"The program can't start because MF.dll is missing from your computer".

Surprisingly, the program does then start!

I also get the same errors when using our own app which uses the NDI SDK DLLs.

Scan Converter Mac cursor tracking issue

Par kelbyadmin
We've run Scan Converter on both Windows and Mac computers (OS Mojave). The mouse tracking seems pretty accurate on the Windows machine, however the cursor tracking on the Mac is way off. Anyone else having this issue?

Premiere Pro Crashes with SPHQ Files and NDI 4

Par rlsafran
I installed NDI 4 this weekend on both of my editing systems. Premiere Pro 19.1.4 (5) and 17.?.? crash when I create a sequence using SPHQ recordings from either a 460 and TC1.

Has anyone else tried this yet?

Scan converter/studio monitor 4 will not display secondary output from laptop

Par SupernovaServer
My goal is to be able to have a graphics machine running powerpoint in presenter view, with the main powerpoint output sending via ndi (in 4k@60) into another computer running resolume (which can take in ndi sources natively).
Currently I am testing this on a Lenovo laptop connected to a 4k monitor or a 4k headless adapter to create the secondary 4k display.
At first, studio monitor was only receiving black. As per a forum recommendation, I set the newtek apps to run on the embedded intel graphics instead of the nvidia 106 0gpu. I was able to pass video at this point, but only the laptop monitor feed. No matter what I tried, the secondary desktop would not show up in the list to view in Studio Monitor.
I did all of this locally on one laptop so as to rule out networking issues, though I did check and the main laptop screen did pass to other computers fine.

Does anyone know how to make this work? If I could send 4k graphics via NDI it would be an amazing option to have on show site.

Thanks

NDI 4 with Premiere

Par fgolman
Did I recently read somewhere here in the forum that it's possible to use live files that are being recorded on an AE3 system, and growing, in Premiere with NDI 4 tools?

That would be amazing to be able to edit files that are still in production, rather than having to capture them in Premiere or copy a recorded file from the TriCaster upon completion.

Scan Converter Not Working

Par Tek_Soup
well it 1/2 works. It will send the webcam video and audio wich is a elgato camlink 4K, but it will not send the desktop? it shows up but is just blank. really strange, im thinking it has something to do with the intel/nvidia gpu settings. This is a laptop , I have changed settings so it should be mostly useing the nvidia gpu in the Nvidia control panel. win 10 1903 scan converter works fine on all my other computers, Version 4 NDI tools.

Par Mark5000
Hi I've been trying to download IsoCorder from the page https://www.newtek.com/ndi/applications/isocorder/, but the request button does not respond or times out. (Tried with Firefox and Chome, on several different machines)

Is the two channel IsoCorder available at the moment?
Is anyone else having problems downloading IsoCorder?

Thanks,

Pauses in LW

Par clborrelli
I have the newest MAC PRO and using LightWave v 2015.3 and every time I try to do anything
LightWave pauses. Even if I use v 2018..07 or v 2019.1 they all do it. This has been going
on now for over a week. Has this ever been brought up as a problem ??? Could it be that I
have too many versions of lightwave in my applications folder ??? I only have one open at a
time. and they are very simple scenes.

Has anyone have any ideas on this one ???
Thanks

SDI inputs on NC1 IN stop working after Windows updates

Par kelbyadmin
Ugggghhh! Everytime a Windows update runs I lose the SDI inputs on our NC1 IN unit. Ultimately, I have to uninstall the last update (sometimes 2-3 updates) before the inputs start working again. Or I have to do a reset to factory in order to get SDI inputs working. This is not only annoying, but a HUGE waste of time!!!!

Is anyone else experiencing this?

NDI 4.0 Scan Converter -> VMC1

Par Meekel
Has anyone tried running Scan Converter from NDI 4.0 Tools and viewing the feed on a VMC? On both of our VMC's it is incredibly laggy. If I view in Studio Monitor on a PC it looks completely fine.

Skype/Zoom NDI Server Audio Crackling

Par rlsafran
Haven’t used my Zoom/Skype servers since NDI 3.8 came out. I’m hearing a crackling noise each time the remote caller starts to speak in my 460 and TC1 recordings. I have two different Windows 10 computers running Zoom/Skype using NDI Scan Converter/Virtual Input and they both have the issue. It’s happening connected to a 460 or TC1. The local Zoom/Skype server recordings are clean.

I’ve tried setting the VB-Audio In/Out, Speaker and NewTek line to 48kHz and 44.1kHz, no change.
I downloaded NDI 4.0 and it looks like it’s not currently available as the download file was still NDI 3.8.

Any ideas? I’ll upload a sample audio clip later this afternoon.
Thanks!

NDI 4 Tools not opening Win 10

Par mannye2003
Anyone else having issues opening the executables for NDI 4 Tools in Windows 10?

Ndi-4

Par jkerry211
It the new NDI 4 to some item only on Windows 10 or can Windows 7 use all the available features. I remember the 3.8 some things did not work on Windows 7.

This also may seem unknown, but can I load NDI4 onto the TriCaster system itself?

Scan Converter 3.8 not showing 2nd display as a source

Par dwallace
We run NDI Scan Converter at our church to send the screen displays to our recording system, but something changed ( Windows Patch or Driver update ) and now it will only send the "primary" display as a source. I've updated to the new 4.0 version and have switched the video connections around ( original: DVI on NVIDIA card - primary, HDMI onboard - secondary ... to ... HDMI onboard - primary, DVI on NVIDIA - secondary ) and it will only send the Primary connection.

If I remove the primary display cable boot with the secondary as the only display and then reconnect after it is booted it will send both sources but upon reboot it all goes back to the same.

Any suggestions.

NDI Receiver on iOS

Par smallfly
Hi,

I'm looking to develop a NDI receiver app for iOS. Is it now possible? Has decode support been added to the iOS SDK?
I found the following app - https://apps.apple.com/ca/app/ndi-monitor/id1196221514 - which let me think that this is now possible.

Thank you,

NDI Studio Monitor - Recording Function

Par RockNRollGeek
Is there more info about this function anywhere? I noticed that it drops recordings into the users default Videos folder on windows, Is there a way to configure the location these recordings go in to? (ie: If I need them to not go on the system drive and instead go onto a second hard drive that is more spacious and dedicated for recordings and things, etc).

I'm guessing there are no quality settings to be configured since its likely just a straight 1:1 dump of the ndi feed into a file right?

Unable to install 4.0

Par Footballer
I have used NDI tools for several years now and I have never had a problem installing any version. 4.0 is making me a little crazy. I have installed and deleted this several times, restarted computer several times. Upgraded nVidia drivers to the latest.

After installing I can click on the app and it looks like it is trying to start with a small spinning circle which disappears after a few seconds. Task manager shows nothing is happening. Windows 10 Geforce 1060

I would be grateful for any suggestions to try?

VLC SyncPlay and Tools 3.8

Par SteveRother
Kane
a while back you gave us SyncPlay, an icon on desktop and you could just drop the files into it and they would play repeatedly. Really awesome! I updated VLC to 3.0.8 and I lost everything. I reinstalled Tools Version 3.8 and although it does play it will only play once. I have the player set to repeat but what happens is that the video turns to a green screen after one playing but the audio still gets through. The video is still playing in the player but it greenon the screen. I went to put back the older versions but found a strange thing. I have two versions or Tools 3.8. They are different sizes. I am confused now. Help is appreciated.
