Quick Tip / NDI camera App/Virtual Input

Par : Tek_Soup
I recently was messing around with the Steam Link Feature in steam. well it adds some audio drivers for speakers and sound card and mic to device manager. well dont do it, it will make your NDI camera App/Virtual Input in NDI Tools NOT work, took me a few days to figure that out. I have found that many side programs like Asus Sonic Radar and others will just totally screw it up. Must be some audio driver conflict. well have a great day.

FULL NDI vs NDI HX

Par : rlambert
I am about to take the plunge and buy four NDI cameras for my studio.

Several years ago I heard Dr. Cross from Newtek say that NDI-HX delivered the same quality of image as regular old FULL NDI except for two things:
1. NDI-HX used less bandwidth 20MB vs 140MB
2. the NDI-HX has more latency due to encoding long chains of data....this higher latency being the cost of keeping the image the same quality of FULL NDI.

All in all, he strongly implied that the images were identical.

Now that I am shopping for Cameras I see that some companies make a big deal that their signals and converters are FULL NDI. Other companies like PTZ Optics make a big deal that the images are pristine with NDI-HX

So here is my question.

For a small studio (4 cameras) with plenty of bandwidth (10GB dedicated ethernet) is there an advantage in going with "FULL NDI?"

If all of the cameras are NDI-HX the latency will be consistently higher, but, isn't that not a big deal if they are all the same latency?

Please help me with advice. I am ready to purchase these cameras now; but, can't seem to find a straight answer on this.

Thank you very much,

Rob

NDI 4 Tools - Adobe CC Plugins - Character Animator not showing NDI as an option

Par : eeeniebean
Hello all,

I have Character Animator installed through Creative Cloud on Windows 10.

Downloaded Newtek NDI for Creative Cloud from https://www.newtek.com/software/adobe-creative-cloud/.

(and yes, I made sure to include the options for CC, I/O, etc. - screenshot attached)

The NDI option just will not show up under Live Output under Preferences in Character Animator.

I've looked around for that NewTek_NDI-Transmit.prm and can't find it anywhere, and I'm having no luck finding documentation of what the plugin should be.

I've uninstalled NewTek, rebooted, re-downloaded (making SURE the CC options were selected) and re-installed. Still no luck.

NDI is working - I can run the test broadcast, and I can even get the test broadcast to come in as a source on streamlabs OBS.... I just can't get Character Animator to give it as an option. Seems like it must be a problem with a missing plugin but I can't find it (or documentation for it). Help!

Specs: Character Animator 3.0

Windows 10

NDI loaded 11/24/19.

This Adobe forum thread seems to suggest that I just need to find NewTek_NDI_Transmit.prm.... I can't. Other folks in the same thread seem to be having the same issue.
https://community.adobe.com/t5/chara...0760552#M11495

Can anyone tell me what the plugin for Character Animator is called and where it should be located? Is it the same NewTek_NDI_Transmit.prm? If so - what to do if it's not coming through on the installer?


My next step is to install Premiere just to test out if I can get an NDI output from there. Beyond that I was going to try it on Mac Instead.
Happy to provide any other info or screenshots that might be helpful.
Thanks so much and Happy Thanksgiving to those who celebrate.Click image for larger version.

NDI over VPN with two Fritz-Boxes

Hi.

I have a problem with the connection of two computers via VPN to get there with NDI the camera from PC 1 to PC 2.

I'll describe the structure very briefly:

The first camera is connected to PC 1. The PC 1 (IP: 192.168.178.10) is connected to the FritzBox 1 (IP: 192.168.178.1). This is via VPN tunnel (manufactured by the FritzBox 1 to the other FritzBox 2) with another FritzBox 2 (IP: 192.168.10.1) connected. At the FritzBox 2 is a PC 2 (IP: 192.168.10.20) connected. On PC 2, another camera is installed. On PC 2 should then run the StreamLabs OBS software and I would like to receive there via NDI input the camera 1 synonymous on the StreamLabs - OBS. But I do not see the PC 1.

A connection from the tunnel between the two networks (192.168.178.1 and 192.168.10.1) respectively .0 at the end, is definitely available. Printers from both networks can be accessed from any PC. So the tunnel works fine.

How can I get it because that the camera 1 from the PC 1 via the FritzBox bin to PC 2 can send your data?

I wanted to get the screen of a remote computer or the camera on a remote computer on my streaming PC (PC 2).

Do I have to stop something? At the Fritz boxes or at the NDI plugins?

In the same network, so if I would infect the same computer s.die same FritzBox, then I immediately with my streaming PC PC 1 in the selection list and I can also directly to the camera, or access the streamed signal. That works ... but as soon as I have the VPN tunnel of the Fritz boxes in between, it is not more ...

Do I have to adjust in the Fritz boxes that something should be rerouted? Any ports or something?

And if so, how do I do that? Or can I enter the destination address of the NDI tool somewhere?


The following software is used:

PC 1:
OBS Studio in the latest version (24.0.3)
NDI 4 runtime
NDI 4.7.0 (Installed by Installer)


PC 2:
Streamlabs OBS (Version 0.18.5)
NDI 4 runtime
NDI 4.7.0 (Installed by Installer)


Fritz boxes (7490 and 7560) each have the latest version on board ...

Can someone help me please? Or is it not technically possible to show the camera or the stream via a VPN tunnel?

Thanks in advance.

greeting
Markus

NDI Scan Converter disables G-SYNC in UWP fullscreen games

Par : colecodez
I have noticed an issue where G-SYNC gets disabled when I turn on NDI Scan Converter. It only affects UWP windows games in fullscreen which unfortunately includes the game I play most, Apex Legends.

To test this I had to enable the G-SYNC overlay in Nvidia Profile Inspector. As soon as I enable Scan Converter (from a stream deck macro), G-SYNC immediately disables. As soon as I kill Scan Converter, G-SYNC enables once again. I noticed that G-SYNC still works with Scan Converter if I play in borderless windowed mode but there is a noticeable stutter.

Just wanted to shed some light on the issue for devs and see if anyone might have found a workaround? Specs below.

Monitor:
ASUS ROG Swift PG27UQ 27" LED 144Hz 4k G-SYNC

What are the best specs for a Skype PC Laptop running Virtual Input?

Par : boyler
Hello all,

I've experienced a bit of a headache today testing 3 different machines with Skype + Virtual Input.

I'm running the NewTek PTZ camera, and using Virtual Input in Skype for the video feed. I am not using the Camera's audio input, and using a separate USB DAC solution.

I've tested two Lenovo Thinkpad's with 16GB of RAM and 2.2 GHZ quad core processors today, both running Windows 10. Both have struggled to broadcast the PTZ Camera while receiving a relatively high quality return feed from the Skype guest.

What I find troubling is that I can run Skype TX on a PC Laptop with less Speed and less RAM, and not have any problems.

If I set the Windows performance settings to BEST, I can run a relatively smooth Skype session. The total CPU percentage runs between 40% - 75%. If I try to open another application or move windows around, forget about it - the Skype session goes haywire. Once there is lag or frame drops in the camera's feed, it is NEVER fixed again. The only solution is to start Skype again.

If I run a Skype session on a Macbook Pro with 16 GB Ram and 2.2 6-core processor, using Video Monitor and Skype's Screen Share feature, it runs flawlessly. (Despite the fact that screen share can only run at about 15 fps.) I'm wondering if I should try Boot Camp on the Macbook Pro.

So my question is - who runs Skype with Virtual Input on a PC laptop, and doesn't experience any of the outlined issues? What your specs?

Many thanks in advance.

Compressed Audio in NDI

Par : jainrajath
Hi,
I was looking at NDI SDK for use in the internal pipeline in a project I'm working on. I had a couple of doubts regarding the audio:
1. Is there any support for transmitting compressed audio formats (like ac3) over NDI? Or does it only support raw frames?
2. How does it send the audio frames? Does it compress it internally or send it as is? If it compresses, is it lossless?

VLC Plugin

Par : jaskie
Hi everyone (it's my first post on this forum)!
Recent NDI Tools installations contains VLC plugin, which is working excellently. But there is no additional documentation on it, especially about its configuration and usage. Furthermore, I have found a licence file installed with plugin .dll, which contains GPL licence. If the plugin is really licensed on GPU, its source code should be offered, as the licence states.
Where can I find more info about the plugin, and (maybe) it's source code?
Kind regards,
Jurek

Zoom Server NDI Return to Caller Audio Distorted – Clicks/Drops

Par : rlsafran
I use NDI Scan Converter and Virtual Input with VB Cable for Zoom servers. All audio record/playback sources are set to 48 KHz (44.1 doesn’t work either). The audio returned to a Zoom caller is severely distorted with clicks or drops. This has been happening since last year.

Instant Teleseminar’s return to caller is just as severe and a Skype return has less noticeable scratching sounds that occur above 6k intermittently.

I have Zoom engineering working on the issue but am not able to help them replicate it without using a TriCaster as NDI Test Patterns returns perfectly if Zoom “Use Original Audio” is enabled and the client’s mic is muted (I always enable “Use Original Audio”, but the Zoom distortion happens either way).

Instant Teleseminar returns perfect 1 K tone from the TriCaster, but music files (.wav or 48KHz) have the noise.

Anyone else using Zoom or ITS back to a TriCaster? I’ve tried it on four different Zoom server systems with NDI 3.8, 4.0 and 4.1 and it always occurs from both a 460 AE2/3 or a TC1 (where NDI Test Patterns returns perfectly to the caller).

Attached is an audio file demonstrating the audio distortion - clicking/drops. The noise between
0:21 – 0:23 is me handling the headset.

NDI Discovery - mDNS or Discovery Server

Par : mitreklov
Hi,

We have a large NDI network that contains a lot of devices, some Newtek some not, all producing a high number of NDI sources to a many monitoring and production destination end points.

We are experiencing some erratic discovery behaviour on some of the receive components such as source count varying with sources disappearing for some minutes at a time only to return after a period.
We have been advised that the default mDNS system can become overwhelmed with large numbers of devices all broadcasting mDNS info and that it might be worth adopting a discovery server on the network and using the access manager to direct the discovery system.
I should point out that the network is flat with no routing and all within one LAN. The network is dedicated to NDI transport only, no other traffic.

I understand the discovery server or service is a relatively new method that relies on version 4 NDI components.
The discovery server idea seems like a possible solution in our case, however it's implementation seems to be a Newtek big secret as I've not really been able to find any coherent explanation on setup and operation. Really the only info I've managed to find is contained in the SDK documentation along with the actual Discovery Service.exe

From what I can fathom it does not look complicated, but I do have the following questions, perhaps other forum members may be able enlighten me.

Thanks in advance.

Does anyone have an explanation of how the discovery server works?

I assume only one instance of the Discovery server is required hosted somewhere accessible on the network.

Once the access manager is set to use a discovery server, do the mDNS broadcasts stop or work in tandem?

Some of the NDI components in the installation as yet do not support NDI V4 (updates in development), can the discovery server co-exist with the mDNS discovery method?

Will the devices still using mDNS be visible to senders and listeners even if they are set to use discovery server?

Does the discovery server listen and relay mDNS broadcast to discovery server clients?

Can you run the discovery server exe on a VMC1?

Is there a better way to do this?

Please forgive me for asking the obvious.
