Multiviewer software for NDI sources

Par jbateman107
I hope this is the right sub forum for this question. My issue is trying to figure out a good way to get a monitor with a multiview setup (showing all of our camera inputs) in two different locations on property (neither being in the same building as our Tricaster and main video router). A Decimator 16-channel multiviewer would certainly work but by the time I purchase that and then convert the video to fiber and send it to the two buildings, I'm not sure I can swing this little project from a budget standpoint.

So I was wondering if I could utilize NDI technology and get this done cheaper. I've found some NDI Multiviewer programs... JMultiviewer, Orfast, EMS Easy Multiviewer and then it looks like NewTek Connect Pro could even be used as a multiviewer. But I'm not necessarily an IT guy so how things relates to our network gets a little fuzzy for me. If we're using 8 camera sources, I am multiplying my bandwidth usage by 8 in regards to traffic on the network? Then another probably silly question but if I'm setting up this multiviewer on two separate computers, I'm then doubling the overall bandwidth again or no? Any insight someone can provide would be more than appreciated. Also if you use any of the above programs, I'd love to hear your pros and cons to a particular program.

Thanks

NDI telestrator output format in 1080p or 1080i

Par upsetice
I had installed NDI telestrator recently on my laptop for testing and love this software. When I use the Studio Monitor to check the NDI output format from Telestrator, I found that the video format is in 720/30p. However, my video server is running on 1080i/50 which are not comapatible with this format.

Is it possible to configure the output on NDI telestrator? For example, outputing the NDI video with graphics in 1080p or 1080i.

Thanks!

NDI Scan Converter Running on a VM issues

Par w2tsinc
BLUF: When I install NDI Scan Converter on a physical Windows 10 host and install NDI tools, my NDI Scan Converter stream from this physical host shows up in my streaming software just fine however when I do try the same thing from a VM, the stream doesnt show up in my in Streamlabs OBS.

-I'm running NDI Scan Converter in a Windows 10 virtual machine.

-I want to send that stream to another Windows 10 host that is running the streaming software Streamlabs OBS.

-The virtual machine is running on a type 2 hypervisior, VMware Workstation Pro 15. I've also tried doing the same thing on Virtual Box with no luck

I know something is screwed up, and I'm not sure its a network thing, but I suspect it's a graphical GPU or Direct X 11 thing. The VMs are limited to DX10 I was wondering if that could possibly be messing this up.

If anyone has any information, knowledge in this area, or ideas, it would be greatly appreciated!

NC1 4K fill and key

Par hosko
The NC1 has listed in the manual that it supports NDI to HD SDI fill and key, it does not mention 4k. Is it possible to receive a 4K NDI feed from a Viz Engine and use a NC1 to convert it 4K quad link SDI fill and key?

NDI Test Patterns frame rates and resolution

Is there a way to change the frame rate of the test patterns? It seems to be locked at 1080/29.97p, it would be nice if it could support 1080i and UHD as well as PAL frame rates.

Set source for virtual input by script

Par Bram
Hello,

I want to use the "Virtual Input" software to display a NDI source in 3th party software.

When the pc running Virtual Input is booted before the NDI stream is availible, the selected input goes to "none". It stays that way, even if the originally selected source becomes availible.

Is there a way to tell the Virtual Input application to select a particular source? maybe by restarting it with the stream name as an argument? Or with Devcon.exe supplied in the utils folder? Or a web control panel simular to the studio monitor.

Ideally without anything showing up on the dasktop...

any ideas will be more than welcome


Gr, Bram

Setting Tricaster Output to stream via NDI

Par ChrisNCM
Apologies for what may be a very basic question. I am operating a Tricaster 410, in a studio setting on a network ,with an Editshare RAID as the storage medium.

I want to stream a live program from our studio to Zoom (and also other platforms like YouTube) and save it simultaneously to Editshare.

I understand that the idea is to get the Tricaster to stream to the network, and then use this streamed output as material for a PC running Windows 10 to connect to Zoom etc

But, I have not got past the first hurdle!

I am having problems setting-up the output (in DDR1) to stream via the NDI connection on our network.

The nature of the 410 is that when I "Start a Session", there is no access to Windows. So how do I make the DDR1 output the NDI stream? Is it about the destination in the Publication Cue?

I am lost so any simple help would be good.

Thanks,

Chris

IsoCorder file no good

Par fgolman
I've attempted to record a NDI stream using IsoCorder (latest version, just downloaded). I can see the stream just fine in both IsoCorder and also Studio Monitor.

However, the MOV file it's generating isn't viewable in ANYTHING except the old, unsupported QuickTime player. When loading that file into Premiere CC (v13.x) it says the video streams can't be decoded but it does get the audio side. Won't display in VLC either.

Is this a bug in IsoCorder?

Any thoughts?

Thanks!

NDI out as second monitor?

Par AndersM
Hi,

Is it possible to set up an ndi out as a second monitor without having a second monitor connected?

In other words, I'd like to set up Scan Converter or similar to act as an additional connected monitor.
This would be useful for for example sending a full screen ppt to the Tricaster, while keeping the notes on the laptop.
Any ways to make this happen?

Thanks!

NDI VLC Plugin issue

Par iPullin
Hey,

I'm new here but have been using various NDI software and hardware recently and exploring the possibilities. I want to set up a PC with multiple DVD drives and each time a DVD is inserted it opens in VLC and outputs it as NDI to various screens. I think I can make everything else work, but upon testing the VLC output into Studio Monitor, when showing a DVD menu you can't see where the menu selection cursor is, the thing that shows you what menu item is selected on screen, so there's no way this project will work if I can't navigate DVD menus. When researching VLC forums, the only thing I can find is that the menu cursor apparently doesn't show when using other video output modules other than the default/main one(s), so am unsure whether it's a VLC 'problem' or could be somehow fixed by modifying the VLC NDI plugin?

Thanks

Question about audio from NDi sources...

Par rokestah
Howdy peeps,

Quick bit of bg here... I've been using a TC410 for 18 months now and have an audio issue I hope you may be able to help with.

I work for a university in the UK and apart from delivering web based learning using live video we are involved with our marketing groups in showcasing our facilities and MSc offerings.

So - with the latter we would have a 1hr live event from our studio and maybe x2 remote cameras to bring in to the mix (some of our facilities are huge, could be a wind tunnel or even part of an oil rig).

I use PTZ1 cameras for the location video with a Sennheiser wireless mic HH/lapel connected directly into the Newtek PTZ1.

The audio is clear and works a charm except for the occasional dropout. It never drops a video frame (at least that I can notice) but the audio drops are random in frequency and extremely annoying.

We have a very modern network infrastructure with absolutely crazy bandwidth and all my equipment is properly registered for all the different sub-nets.

Does anyone have any clues as to what maybe causing the audio dropouts?

TC1 stopped viewing NDI sources in UI (works with studio monitor, same workstation)

Par sclaws
I've had this issue intermittently where my TC1 would no longer "see" NDI sources from our NC1 IO, unless I restart the NC1. Now, after running an update on the TC1, it no longer sees any NDI devices. It is, however, still connected to the previously selected source from the NC1 and is passing a/v from that source. If I exit the TC1 and open Studio Monitor, I see all NDI devices as expected. Does anyone have any ideas??? If it works with Studio Monitor, I'd think there aren't any OS settings interfering with this--seems the TC1 is at fault somehow.

I'm open to any suggestions.

NDI Output channel name

Par user243
Is there a VLC command line to specify NDI channel name? Currently the the NDI output from VLC is being read as VLC among the list of NDI sources. Can I specifically define the channel name?

NDI Audio Only - Assisted Listening

Par RossMcIntosh
An idea that has been with me for a while was for NDI Audio streams, not attached to video, or black video.

I've noticed there are so NDI Audio Monitor applications including one on iOS, but my loose understanding is that they monitor the audio of NDI Video streams and consequently still require the full ~100Mbps to listen over WiFi.

Would Newtek be interested to explore the idea of Assisted Listening via NDI App.
I see a few potential use cases;
* Distraction Free Listening at conferences or events so delegates can completely immerse themselves in the content.
* Quiet conferences, typically these you infrared/wireless headphones similar to silent disco instead of typical PA. Distraction Free Listening and also events that have to take place during working hours in shared/communal spaces.
* Translation for multilingual audiences, just select the appropriate stream.
* Event Managers out of the room being able to monitor the event proceedings.

An audio only stream would be quite lite, and reduce the burden on WiFi infrastructure not only for small groups of listeners, but even the full event.



Further development of this could include;
*Closed Captioning
*Audience Response / Q&A - every delegate (or almost every) has a microphone on their person, put in a request to speak along with their name and they could be added to a question queue.

I realise this wouldn't necessarily be in Newtek's direct interest to develop the App side of this, but if the framework was there, it could make for some very interesting developments in the live events side of things.

Thanks,

Ross

Support telling me to refund instead of insight.

Par AskMP
So, I've been having consistent issues with the NDI mobile application. Specifically getting it to have a smooth frame-rate. I was able to document it over various situations and even work with a colleague who has a commercial grade network. Contacting support about the issue, they came back after several dialogs and providing video of the issue, they stated that they are the support department and handle Tricaster systems so I should go here instead of using the link that is located on the application support page.

(All wifi tests were done using both 2.4Ghz and 5Ghz bands on a non-congested network and area)

Windows and Mac Scan Converter -> 1080p30 -> WiFi NDI is great (Monitor, OBS, Wirecast)
Windows and Mac Scan Converter -> 1080p60 -> Ethernet is great (Monitor, OBS, Wirecast)
Mobile 720p30 -> WiFi -> Unusable due to FPS and stuttering
Mobile 640x360 (Low quality) -> WiFi -> Usable but terrible resolution.
Mobile ??? -> Ethernet connection through Hub (to provide power) -> Crashes the NDI application on mobile device
Mobile 720p30 -> USB-C to USB-A adapter -> Ethernet dongle -> Usable

This seems to me like it's a bandwidth issue as a whole. Interestingly, even with extremely lower bandwidth situations like that of going through Hamachi as a proxy, NDI does function (at a low rate) and it shows up. But the mobile device needs to be placed on a massive WiFi connection before it is available to choose as an option both with low quality more or high. As a hunch, I would assume this is because you're still using the original protocol for it and not the lower bandwidth requirement of HX. I think, long term I can see about getting around this but it is a bit disheartening to know that what I hoped to have as solely a backup option for situations can't be so. Planning out the tech around it and requiring it to be connected to something that can (hopefully) be providing power to the device as well as Ethernet out (and use USB-C) is going to be a feat in and of itself. I was hoping to see this as a potential for a mobile camera for adding into layers with minimal effort. A "Oh crud, we need to get that shot ASAP, here's my camera, go run over and capture that!" device if you were.

My colleague in Australia is running a UniFi commercial system, here is the video of our conversation and the results in real time:
https://www.youtube.com/watch?v=fK37W-YaSqI

The first response after that video was sent to support was

Quote:

Thanks for providing that insightful video displaying the issues with the NDI app. Though there is no news on development if there will be an NDI HX app in the future. If users are unable to get the app to work smoothly on their network, or unable to have the phone connected wired (which defeats the purpose, but other users have had success with only wired connections) then we recommend they get a refund. Apologies for the inconvenience with the app's functionality.
to which my response:
Quote:

I'm not interested in a refund. Sure. 25$ is insane to pay for an app (let alone one that doesn't work as intended) but I'm also interested in see the evolution of this. You've had the same application released for 4 years now with no updates. NDI is fast becoming an industry standard among broadcasters, both professionally and with high level hobbyists. Getting it to work with a wired connection, as you stated, defeats the purpose but it is possible to get with the low quality mode. When I have seen it used in the wild, I notice that people are in fact using it in low quality mode. That 640x480 does seem to be fine with solid networks. It just seems odd to me that we have devices in our pockets that can handle recording in 4K, streaming in 1080p60 yet something like the NDI camera cannot provide 720p.

The fact that you, as the developers of the protocol, are stating instead of you looking into making the application (which people paid for) a viable continually developed resource, that I should just get a refund and stop trying.

You truly have a potentially amazing resource at your fingertips here. Modern phones have cameras in them that are now rivaling low end commercial grade sensors. Many of the cameras are not better than high level USB cameras. You have the technology and protocol to make NDI a best option for people yet you're choosing instead to recommend people to get a refund because you're not investing into continued development.
which was followed by them simply stating that this is not their area and that I should go here.

NDI to HDMI

Par rayg75
We are looking at switching to a NDI video setup at my church. We have Cat6a and gig switches run throughout the campus and to all of the the TV's. From my understanding we can output an NDI signal from the Tricaster across the LAN. What would I need to be able to convert the NDI signal back to HDMI so the TV's will be able to display it? We are looking at sending to 10-20 TV's. Sorry if this has been covered before, lots of data to sift through on this site.

This implies that the N2 is not licensed, but it is.

Tried reinstalling NDI Tools 3.8. No change.

Installed a vMix trial. Voila! Studio Monitor can now see the NDI|HX stream.

This was perfectly uniform across all three, brand news systems. It implies that the HX driver is not correctly installed using the v3.8 installer.

Looking for mini PC/digital signage PC to run NDI Studio Monitor

Par kidgkodiak
Hi all,

I'm looking for either a mini PC or stick PC in the sub $300 range. Looking just to run NDI Studio Monitor @ 1080/30fps - something to mount to the back of a flat screen tv, preferably running on our gigabit wireless network. Nothing else, they're just used as additional screens when we see fit.

I'm eyeing either the Z8350 processor sticks w/ 4 GB ram, those seem to range in the sub $200 market. Any other ideas or anything else I should be aware of?

Dual Networks for NDI

Par teganscott
Hello,

I'm having issues while having 2 separate networks running at once. The NDI content needs to be on Network 1 (all local NDI feeds via a un-managed 10G switch). Network 2 has internet and internal OSC messaging. On the forums here I read about blocking port 5353, mDNS, Bonjour, 5960+n feeds/computer on the second network. This works well because that network is connected to a router, and can be blocked easily enough with Windows Firewall settings on each device. Well, I suppose in theory, but it doesn't seem to work. Is it possible that these devices could not be going through this firewall because they are connected through the same switch?

I've also tested using the Access Manager and read the .pdf that came with the tools. I tried working with the remote sources tab (despite the manual saying it can flip flop between networks). I am not sure how the Remote Sources has an effect on the incoming streams. When I add a 'Receive Group' that does not exist and add IP addresses to the 'Remote Sources,' no streams actually come through.

Any help at all would be much appreciated.

Thank you,
Tegan

Suggest Switch for Buffer memory, QoS and blocking

Par moha20106
Hi all,
This is the first time run NDI system on my own media server
All i need is to capture the screen from 3-4 laptops
Also i don't need latency or delaying to my system

I read more articles about the best switches but i need your support to suggest Brand and model to buy please


I found in the suggestions the switch must be with the zero "Buffer Memory" for zero latency

Also the switch must have QoS and non-block options

I don't know if i really need these options or not
I don't know if i need Managed or unmanaged Switch

So please suggest Switch model for me
8 or 16 ports

Thanks for your support

NDI Scan Converter With Streamlabs OBS

Par bhayes9614
Hello everyone this is my first post so bear with me. I have more of a complicated dual PC streaming setup that has been going strong thanks to NewTek's NDI Scan converter software. I can stream most games fine with my gaming PC and Streaming PC however anything that uses Anti Cheat software such as CS:GO with Faceit it will result in a black screen in OBS. If you were using a single PC using Game Capture you can enable the Anti Cheat Compatibility Hook to bypass this issue. However that's not an option when using NDI. Would that be a feature that NewTek could implement or Streamlabs? If anybody has any thoughts please let me know thanks!!
