CPU with AVX Instructions

Par : ronsatter
I have a problem installing any NDI Connect software ... even the free Connect version.

I am trying to install on PCs running Windows 10 Home.

What does this message mead? ( NewTek Connect requires a CPU with AVX instructions )

Do I need a special CPU ??

RoI is disabled when computer restarts

Par : Laburete
I am using the NDI tools to capture an area of the screen and use it as a virtual camera in a Chrome window, the problem that I have seen is that sometimes the Region of Interest is disabled after a reboot and the whole screen is captured. Has anyone come across this? is there any settings file that can be defined?
Thanks in advance.

Release notes

Par : jgeduldig
Is there a document that lists fixes and other changes between versions of NDI SDK and NDI Tools?

Unable to connect my phone to Virtual Input

Par : Nic Dr
I have the newest versions on both Virtual Input on PC and NDI HX Camera on my iPhone 7. Virtual Input can't find my phone when i use the camera app on my phone, it says: " No NDI sources found."
I used this app in june for school and worked perfectly fine and now it can't seem to work, also for school.
Thanks!

Unable to load kernel driver (video)

Par : tomgo
Hi,

I have used NDI Tools (specifically NDI Virtual Input) for a while now on my old laptop under Windows 10 Enterprise Version 1909.

Since last week I have a new laptop (Microsoft Surface Book 3) which had Windows 10 Version 2004 preinstalled. I have change the license to Enterprise and installed all latest updates. Then I ran a script from my companies IT admins which was basically installing a virus scanner and made some basic settings like mounting common shares.

When I install the latest NDI Tools 4.5 now (just downloaded few days ago) everything looks good first (no error messages). But when I start NDI Virtual Input then (same behavior with or without reboot) I get the following error message.

Click image for larger version.  Name: 2020-09-17_02-20-32.png  Views: 9  Size: 13.9 KB  ID: 148734

In the UEFI menu I have disabled secure boot completely (no change). Also, I have put the OS into kernel driver test signing mode (no change). I reinstalled NDI Tools several times under these different conditions (no change).

I wonder if this is a known issue. It looks to me that there is something different on my machine which "NDI Virtual Input.exe" is not able to deal with. All other hardware drivers are working completely fine, so it might not be a general problem.

Can somebody perhaps tell me what exactly is the condition which is causing this error message?

Install failure

Par : KRTW
Hi. NDI is fantastic technology and I hope I can get this working.....I've installed thousands of programs and never seen anything like this. So I signed up, got my link, did the download, ran this install and everything seemed to go well. THen I started the app NDI Studio, and it started the install program for my Yamaha ASIO drivers.....yup. Starting the program ran a program to install Yamaha ASIO drivers, that are already installed....first time I just cancelled the install, but it would not shut down....So I rebooted and tried again....but the install program was still running so I had to power off and remove the battery....then I tried to run the NDI Studio again, and the install started....there were error messages and the install ran forever....I had a show to run, so again shutdown, powered off and gave up.

Any ideas here?

NDI Access Manager - discovery service

Par : herlsone
Is there more detail on how these tools work? I see access manager stores data in a appuser roaming xml file. But it does not store the discovery server data in that file and I cannot find another location of data being stored.

If you use discovery service, does it completely ignore the output and receive groups?
What defaults are needed in groups?
If discover server is enabled are any ports needed to be forwarded at all? or can all machines now see and receive what the server is keeping track of?

Any tutorial at all??

Thanks

Scan converter - region of interest displaying green bars when taken as input

Par : hypohamish
So, best way I can show this is with a GIF

https://i.imgur.com/P33irQK.mp4

I have scan converter set up on a laptop to capture a region of interest (screenshared powerpoint from zoom)

I'm taking that as an input over NDI into Vmix - but when received into Vmix, I see these weird little green bars. The bars move/change shape when I resize the ROI on the laptop.

They do not however appear at all on the laptop or at any point with configuring the ROI.


Is this an NDI/Scan converter issue, or is it a Vmix one? A colleague with the exact same setup doesn't experience this.

MacBook issues sending Keynote with video backgrounds

Par : highab
Hi,
We have an all-mac system. We've been using it OK for 6 months now.

I have, however had to be creative in sending a keynote from a macbook pro 2012 to the network, yes it's old but we tried the same file with a newer macbook and still things didn't work quite right.

We've been using VmixDesktop capture of Display 2 over the network without problems for our iMacs and MacMini since showing screen 2 of a MacBook Pro via NDI scan converter seems impossible since to select Keynote screen 2, Keynote screen 2 needs to be activated and if it's activated then keynote blocks us from going into NDI scan converter and selecting the feed to be sent or making any changes to the quality of the feed.

When we tried a macbook with VmixDesktop capture of a file with a video background we did have output BUT:


1) The slide shown via HDMI and the slide shown via NDI were not always the same and sometimes took forever to catch up
2) The background video stuttered, it wasn't nice and smooth as it should be.

I have been doing tests with a different laptop mac that doesn't have much RAM at the moment. Even if I remove the background video from the Keynote file and play just the background video using QuickTime player, it plays properly, waits a bit and then plays again, it's never a smooth feed, whereas playing something on YouTube and showing it over NDI seems to work without any problems, proving that the NDI feed can work.

So although I do have a workaround solution, sending the feed via HDMI into our video switcher and using the feed from the video switcher as the NDI source which then outputs video that is very smooth. I'd really like to understand what the problem is.

I've tried manual ethernet configuration on the 2 tests macbooks, setting it to Jumbo but I don't know what else to try.

The NDI signal taken from the video converter via a BirdDog mini works just fine, so it doesn't look like the problem is the network.

Does anyone have any ideas or point me in the direction of other tests to do to try to work this out?

Many Thanks!

NDI & Sony SRG-X120 - No picture

Par : kadams79
Recently purchased a Sony SRG-X120 to use for live streaming via OBS. I currently have the camera and computer connected via ethernet to a Linksys EA9500 router. The computer is Windows 10 with a Gigabit ethernet port. Camera firmware has been updated, the NDI license has been added to the camera, and it shows as a NDI source in Studio Monitor. Unfortunately there is no picture. I've looked through the forums and Google articles for two days with no luck. Can anyone help me figure out what I'm missing?

NDI 3.0+ Runtime

Par : NightFox
I am looking for this version I need the NDI 3.0+ Runtime PKG for macOS. Does anyone have a copy of this? For I have an older Mac that I am running with max OS 10.11.6 and I would like to have NDI put on it so I can run a i.link or IEEE 1394 Camera. But I having a nightmare of a time trying to find an archival for this program

I would use the new version but it would seem that El Capitan does not work well with any anything above OBS 19.x and that means that only NDI 4.2.2 will work with that version and it needs the NDI 3.0 Runtime.

Any help would be greatly appreciated.

Unless you can help me to understand how to get a new version of OBS to work correctly and will work with the NDI 4.5.1 run time.

One of the problems is related to the fact that with the OBS 24.x, 23.x, 22.x version is that it will either not allow the transition to other scenes or will keep the program screen black. For I see the image in the Preview under studio but when you try to translate it to the program view or streaming view, the screen remains black.


Thank you in Advance

No audio from NDI source in OBS

Par : thomasvt
Not displaying any audio levels on a Win 10Pro laptop. Have checked and do not see any issues with OBS settings.

I have tried from another Win 10 computer and that seems to be working okay. Also tried from Ubuntu laptop and it works okay.

Have run the NDI Analysis tool on the two Win 10 laptops for comparison and the output files are attached.

Is there anything I need to check on the Win 10 laptop to get the NDI audio working. Could it be any firewall or AV which may be filtering audio. Is there anything I need to check on the NDI drivers?

Talkshow 4000 over NDI horribly jittery on a brand-new TC1...

Par : Bruce A Johnson
Sorry for the cross-post over in the Talkshow forums, but this is an issue I *have* to get fixed.

Just last week I traded in my TC460 (bye-bye W7) for a TC1. The install went well, everything seemed to be in line, but in testing with our pre-existing Talkshow 4000, it has become pretty obvious that in the path from the TS to the TC1 something is quite unhappy. The video in the TC1 is jittery and wildly out of sync. Luckily I can record the Talkshow signals internally - that saved my butt on a high-profile guest last week on a taped show - but the majority of our shows are live, with from one to four Skype channels in operation.

So: Anyone have any insight? As you might expect, our LAN in the building is basically wide-open, with everyone working at home. In fact, the only variable here is the TC1 - the 460 had no issue with the Talkshow signals.

Is there some "best practice" for the TS4000 and the TC1 I may have overlooked?

Thanks all -

Introducció
Per a la finalització del primer bloc del Postgrau de Tecnologia i escenificació digital de l'Institut del Teatre de Barcelona volem convidar als i les alumnes/as del curs a reflexionar sobre la precarietat dels treballadors de l'espectacle. Ens trobem enfront d'una situació que ve de molt lluny però que es veu aguditzada en aquests temps de pandèmia. Es tracta d'un sector heterogeni i fragmentat, dependent d'altres sectors, com el de la Cultura i Esport, Indústria i Turisme. Això es tradueix en una fragilitat estructural que demanda un esforç complex de reflexió i mobilització allà on sigui possible. Proposem una trobada/debat sobre aquests temes que afecten directament la comunitat.

NDI for MS Teams Released!

Par : Red Dog Records
Good news - You can now use NDI with teams.
Bad News - If you thought the SKYPE watermark was big...Now they have the words "Microsoft Teams" on each video feed.

We are still messing around with it, but it looks promising - IF we can get rid of the built in endorsement.

I am hoping the admin level of bandwidth control will apply to all participants.
More testing this week...

NDI|HX Dropouts and Missing Info in NDI Analysis

Par : CUCMedia
We are experiencing audio dropouts when receiving NDI video from Newteks NDIHX-PTZ1 and PTZ Optics cameras on our corporate network. Dropouts have occurred when receiving video with either Studio Monitor or the Tricaster TC1. In an effort to diagnose the issue we turned to the NDI Analysis app (see attached reports). There both the Newtek and PTZ Optics cameras report using an unknown codec and data rates of zero. The TC1 report looks normal, though the "Video recv" variation is a bit disconcerting. This all brings me to my question:

Is the missing data in the NDI Analysis report a stem from an inability to parse the information from an NDI|HX stream or another symptom of poor network or machine configuration?


9.9.2020 - NDI Analysis - NDIHX-PTZ1.txt

NDI-HX on iPhone to Screenflow Blocks Audio

Par : geopick
I am using NDI-HX to send video to Screenflow on my iMac. The video works fine, but when I mute audio on the iPhone and set audio input to NDI Audio no sound is recorded. With NDI Virtual Input active, neither the iMac's internal microphone nor an external USB microphone record audio. I am wondering if the problem is an incompatibility between Screenflow and NDI Virtual Input?

Diagnosing inconsistent frames with the Analyzer of NDI HX camera's

Par : ryzen6652
Hello guys, I hope to gain some knowledge here to help me along.

First just a brief summery of my technical setup
I often have setups with multiple PTZ cams, all wired up to a workstation running vmix.
All cams are NDI HX and about 50% of then run 4k 30fps, and the other 1080p 60fps.

Since the start the 4k cams have given me somewhat inconsistent performance that tends to get worse with scaling out, and i can't seem to really pinpoint what the weak point is.
With a framerate of 30fps it is just not as smooth that you would think, its just always a bit of stutter here and there.

Its a closed system, with only 1 network hop/switch so no mdns or any other factors.
The workstation is a 24core TRX with 64gb ddr4 3600mhz and a RTX 2080s, so more than enough power.
It is linked to the main switch with a 10gigabit Ethernet port and the PTZ are linked to the 1gb Poe+ ports on the switch so bandwidth is plenty.

I tried lots of tweaks on the switch, some seem to influence things a bit but nothing that got the desired result.
Same inconsistent behavior is also present when just linking a camera directly in the workstation.

So the NDI analyzer looks really promising to diagnose the camera's and changes in the network switch, but i have some problems to interpret the given results, even after reading the included documentation.

I have noticed the video recv value is very depended on resolution, bitrate and encoding parameters.
But when setting everything so it goes as low as possible it results in vmix dropping most frames, so now i wonder if its better to focus on deviation in between reported values instead of absolutes?
Also some of my values are so far of the quoted values in the documentation I am wondering how can this give sort of smooth image, or am i understanding this poorly.
I'm not ruling out the cameras are to blame because there Chinese OEM sold by local company camera's that are fairly priced accordingly.
Although i found out this is the same OEM that builds ptz optics, hubble cam and a couple of other big brands so they should have some knowledge.

I would like to understand the analyzer better so i can optimize as much as possible with the given hardware.

So i hope to get some tips and pointers.

I have added a txt from 3 ndi analyzer runs.
1 is 4k 30fps bitrate 52100 - the OEM added that high bitrate sort on my request for preventing compression artifacts in very complex scenes.
2 a 4k 30fps bitrate 10240 - Half bitrate of what normally is max
3 a 720P 30fps bitrate 10240 - as a very low end control run

any help is appreciated.

Modulo Pi launches new multi-projector auto-calibration module

Par : yannickkohn

Paris, September 2020 – Modulo Pi is pleased to announce the immediate availability of a new multi-projector auto-calibration module. Available as an option for the Modulo Player and Modulo Kinetic media servers, the auto-calibration system allows to automatically align multiple video-projectors on planar, curved, and dome surfaces for a pixel-perfect projection.

Designing the next generation of media server solutions, Modulo Pi is pleased to announce the official and immediate release of a new multi-projector auto-calibration system.
The dongle-based module allows to automatically handle multi-projector soft edge blending and geometry on planar, curved, and dome surfaces.

The auto-calibration module comes as an option for the Modulo Player and Modulo Kinetic media servers, ensuring a reliable and significantly simplified workflow.

Working with Modulo Player, up to one server can be supported, i.e up to 6 x WQXGA outputs, or 4 x 4K outputs.
Working with Modulo Kinetic, the auto-calibration option supports multi-server configuration, resulting in an unlimited number of outputs and resolution support.
Modulo Pi’s auto-calibration system can handle independent calibration groups, as well stacked video-projectors.
In addition, a versatile masking feature ensures a perfectly fine-tuned projection.

Fully developed by Modulo Pi, the auto-calibration module relies on Power over Ethernet (PoE) cameras to offer fast and simplified cabling.
Using the Modulo Pi media servers equipped with the auto-calibration option, high-precision edge blending, warping, and media playback is achieved within minutes and with zero latency.

In summer 2019, design and production company ECA2 worked with a preview version of Modulo Pi’s auto-calibration module for The Legend of Pangu, a spectacular show in brand new Chinese Culture Exhibition Center in Lanzhou, China. The auto-calibration module was used to automatically align 20 x Christie projectors and deliver a 2.800 sqm 3D video mapping on a dome surface. “This is totally revolutionary technology”, explains Clément Rabréaud, Technical Director for The Legend of Pangu. “It takes just 13 minutes to run, which means that if a projector ever needs to be replaced, the whole system is back in focus quickly.”

NDI Studio Monitor unable to run on my computer

Par : abo
Hi,

Windows 10 2004 up to date
NDI Tools 4.5

Studio Monitor displays the following error Window
------------
Error running Video Monitor

Your GPU cannot run Video Monitor.
OpenGL Shaders not supported.
------------

But …
Up to date drivers (12 august 2020) from NVIDIA site are installed for my graphics card (NVIDIA GeForce GTX 1660 Ti with Max-Q Design).
The drivers support OpenGL 4 …. including Shaders ….

Therefore I suppose that Studio Monitor detects wrong graphics card.
There is a second GPU (Intel UHD Graphics 630) on my laptop.
But this GPU is disabled and must remain disabled.

Most probably this is a bug in GPU detection by Studio Monitor.

Do you have any idea on how to fix it*?
Any help will be appreciated
Alain
