Hello!
I have a question about lan connection between two PC for streaming.
I made giga lan connection and when i stream 2k video on youtube using second PC there is variable lan load, that cause some quality problems on video stream.
There is separate LAN between PC with two giga network cards only for OBS.
So, question sounds like this:
Can I make a connection between two clients OBS with NDI plugins constant?
Now i see LAN load 40-200 mbit/s, but can i make constant 200 or 300 mbit/s between thoose OBS clients to improve video quality?
Can somebody help me with this?
tnx.

Is there a way to make it so that an NDI app can only use one NIC for transmitting?

I have a system with 3 active NIC's for different purposes (media transfer, control/service, streaming/etc) and the NIC that gets used isn't the one that I need it to work on.

All three NIC's use a different IP range and are hooked up to different switches as well.

According to the NDIAnalysis tool (along with studio monitor) it shows which NIC is being used, but it isn't the one that I need it to use.

Any help would be greatly appreciated!

Hi,
Seems that the StarLeaf app v3.6.33 (video conference system) does not show anything if "Newtek NDI Video" (latest 3.8) is selected as Camera. Checked that it works just fine with Skype.
Guess it's an issue with StarLeaf, what should I ask their support in an attempt to have them fix it?
Thanks,
/Richard

Hi, currently looking at the Panasonic AG-CX350 and wondering if anyone here has any experience with using the built in NDI on this camera? Seems like a very attractive feature to have, in addition to the fact that the HDMI and the SDI can output simultaneously (among other stuff).


Would love your thoughts on the NDI implementation (as well as the camera in general!). We use a TC1 in studio but would also probably use the camera for mobile streaming/shoots via OBS.

Thanks!

Hello everyone!

This is more or less a copy-paste of a reddit post I made. Hopefully someone here will be able to shed some light.

I'm attempting to use NDI to send a capture of a computer game from one computer to another. The computer running a game is using OBS with the OBS-NDI plugin (I've also attempted to use NDI Scan Converter with the same result). The scene and output resolution match each other, and have been tested at 3840x2160 and 1920x1080, both at 60 FPS. NDI is used in non-low bandwidth mode. The gaming computer is connected to a networking switch over 40 Gbps. The receiving computer is also connected over 40 Gbps. They're in close proximity to each other with a couple of hundred microseconds of latency at most, within the same subnet. The highest bitrate that I've seen using a feed that is virtually impossible to efficiently compress (random colored noise, high entropy) was around 380 Mbps.

Regardless if the NDI output is received and viewed locally on the "gaming" computer, or on the receiving computer over the network, very noticeable compression artefacts can be seen, both banding and microblocking. This is an issue I've had with NDI since I started testing it about a year and a half ago. Despite searching around, it seems there hasn't been a lot of research into what NDI actually does to the source, visually.

If someone is sitting on more knowledge than readily available, perhaps a way to force NDI to not be so aggressive on saving bitrate, do tell.

I can add some images to show the issue. If the interest is here, I can put several of them in an archive and upload to a file service.

Hi,

I have been having a lot of trouble with NDI when I connect up my ASUS ROG i7 Laptop. I have the laptop connected to a simple Ubquitii Edgeswitch 8 and I also for test purposes have an i7 Desktop connected to the switch. I am playing 2 video files using VMix on both. I have run NDI analysis and this is the results.

1: name="ASUS-VIDEO-LAPTOP (vMix - Output 1)"
host="192.168.79.38"
port="5961"
type="NDI|HX"
2: name="BUSINESS (vMix - Output 1)"
host="192.168.79.39"
port="5961"
type="NDI"

As you can see the Laptop output is stating it is a NDI/HX source but how is this possible. Below are the source readings for both NDI streams:

Can anyone shed any light on this. The problems I have is as soon as I plug the laptop into the workflow NDI traffic between sources on my network breakdown, lose connection or just have framehold issues. The laptop is using a Thunderbolt 3 dock with a 1Gb Lan socket.

TC1 has serious issues with NDI inputs through the switcher to Line.
Link shows the issues easily.
https://drive.google.com/open?id=16e...6ESlMiJJEwAFRv

NDI streams viewed within Studio Monitor Tools 3.8 are okay but through the TC1 the problem is evident. See Time mark of 29sec.
The TC1 has latest F/W as well as the NC1 I/O. Updated GFX driver as well as NDI Tools 3.8 on each device.
The video made above was with current operational network. Bandwidth required is suitable, as Studio cameras are 2160 50p into NC1 with TC1 Session setup as a 1080 50p Session.
The severe picture breakup occurs easily through the PTZ camera and disappears when NDI sources are not to Line or P/V (obviously) or Studio cameras brought in to TC1 via SDI instead.
The NDI output of Studio cameras show evidence through the TC1 as picture output having 'dropped frames' which is evident when there is movement ie, Pan.
Checked system with another local 1Gb switch with TC1 and NC1 connected. Problem is still evident.
CCU setup can output Quadlink for NC1 as well as 1080 50p in SDI format.
Need to resolve into why the NDI is failing as SDI is our fall back mode.
Any solutions to why this is being experienced would be appreciated?

Hi
Trying to download Airsend Updater (to use with Caspar CG) but when I click the download button on https://www.newtek.com/ndi/applications/ I am sent to https://www.newtek.com/ndi/tools/ where I am only able to download NDI Tools. Or is there something I am missing? :screwy:

This afternoon I'm editing some video on my vMix system I notice that when I launch Premiere Pro 2019 it stalls for several minutes displaying a screen that reports "Loading Newtek_NDI_transmit.prm." And idea what's up with that?

Scan Converter open in taskbar but when I go to change any option it closes as soon as I hover the mouse over the icon, This also happens if I goto show hidden icons. I am not getting any image in Studio Monitor just a blank black screen even though I can switch to different monitor sources on my GTX 1080 ti. I can display test patterns.
I have been using this setup flawlessly for some time this is a recent issue

Will NDI run over a VPN if you have a solid connection between the two endpoints?

I work for a fiber to the home system. We have a city wide network and we can create VLANs that are city wide. Will NDI work in this case? For all purposes it should be no different than being in the same room I think. I am thinking of working High School Games from our office and just sending a couple of people to the field to shoot the game. This would save a ton of work seting up and breaking down. I have two Newtek PTZ HX cameras and a Spark

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!!

Hallo,

We have unfortunately no audio with our Kiloview N1.

#1 We have already reinstalled NewTek Tools twice
#2 If we save video to SD card audio is saved. No issue.
#3 If we use HLS instead NDI, no issue.
#4 we tested NDI receive at two PCs - the same issue.

Only NDI has some problem.

OS: Windows 10 Pro

Has somebody an idea what the reason could be?

Thank you for your help.

Best regards

I.

I've reported this on Fogbugz, which hopefully is still the correct way to get this logged?

Anybody else seeing this issue?

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

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

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?

Thanks all.

I have several brand new SFF Windows 10 PCs. They are to feed some projectors from an NDI or NDI|HX source. They have NDI Tools 3.8 installed.

Using Studio Monitor, selecting an NDI source everything works flawlessly for days.

Selecting a Kiloview N2 wireless NDI|HX encoder all system show an error message,



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.

Hi! If i have an ndi signal, and i have a videowall made from 2 smart televisions with Android, how can i show it on these? There is an Android version of Studio Monitor to put fullscreen?

Hello,

It's very difficult to know the real differences betwenn a "spark 4k" and a "birddog 4K"...

Naturally, the BD is bidirectional but what about latency, control, quality, compression?
Does anyone use these two NDI converters?

Thanks
Tony
