Problem with the NDI HX Camera Android app

Par : shimatani
Hi I'm having a problem with my NDI HX Camera android app.

It has a black screen, however, I already gave permission to the camera and nothing.

I'm uploading the photos from my device and I canceled and installed it again

but my first refund hasn't arrived yet and I had to pay again.

thank you for your attention

NDI for MS Teams Released!

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 support in Nimble Streamer

Par : Softvelum
NDI is now supported in Nimble Streamer, a software media server by Softvelum.
Nimble Streamer can be used as an efficient bridge between live production environments and global Internet.

NDI input
Nimble Streamer takes NDI input and handles it for further processing.
  • Get NDI from local network, decode it and make multiple renditions if needed.
  • Encode content into H.264/AVC, H.265/HEVC, VP8, VP9 with supported encoding libraries.
  • Re-package into other live protocols like SRT, RIST RTMP, HLS, MPEG-DASH , Icecast etc
  • Record with DVR and play via HLS and MPEG-DASH.

NDI output
Nimble Streamer can take any live stream input and create output NDI stream.
  • It takes input via supported protocols like SRT, RIST, RTMP, MPEG-TS etc.
  • Transcode and send the content via NDI into local network.

NDI monitoring console tool
Along with implementing NDI in Nimble Streamer, we've made a console tool for diagnosing NDI streams.
It shows the list of active NDI streams in your network and provides detailed information about video and audio frames.

More details are shown on Nimble NDI digest page and in setup technical article.

NDI Virtual Input Lag

Par : TPS Chris

I was soo excited to hear that this would help us bridge the gap between OBS and Zoom! I installed it and got it up and running and while I'm able to see everything great right after opening, a few minutes into our zoom meetings the input will lag to the point where it'll just stay frozen. I love the application and the idea of what it should do, just not certain why I am experiencing this. I've been searching everywhere trying to find if anyone else has had this issue, but haven't come across it. Perhaps someone here can help troubleshoot?

Running on:
2019 Macbook Pro running Catalina
2.4 GHz 8-Core Intel Core i9
64 GB 2667 MHz DDR4
AMD Radeon Pro 5500M 8 GB
Intel UHD Graphics 630 1536 MB

OBS - 25.0.8

Zoom - 5.0.4

NDI Integration with Reaper DAW via Reastream

Par : livepad
Sienna NDI Processing Engine now has a pair of new modules which provide bidirectional, low latency integration between NDI and the Reaper DAW, using the Reastream protocol. A bit like DANTE or AES67, but much simpler, Sienna's NDI/Reastream support allows blocks of up to 8 channels of audio to travel between the NDI world and the Reaper DAW (and back again). On-prem this is a great, simple alternative to the complexity of Dante / AES67, but the real win is for Cloud based production, where DANTE and AES67 can't pass between instances because they are generally multicast. Reastream breaks down the barrier and allows NDI Based cloud production with NDI to offload the audio mixing role to another dedicated audio - specific machine, then merge the mixed audio back with the video.

New to NDI - Need Instructions

I’m trying to stream with Livestream Studio and testing NDI sources On my network. I notice the NDI Tools package is different for Mac and PC. And I have no idea what each of the Tool apps do. Like the Scan Converter and the Monitor. Which app actually sends video/audio to the host computer so LSS can see it? Why can’t I get audio from the Mac laptop? Is there an instruction guide available?

Ndi 4.5

Par : kanep
NDI Tools 4.5 has been released for Windows and Macintosh. Updated NDI Analysis and SDK, the Unreal Engine NDI SDK is now available.

Here is a (very) partial list of improvements from the SDK docs. This release is under the hood improvements, NDI Tools operate as they did before.

* Significant improvement to UDP sender that should dramatically improve the performance on many systems and networks. This should reduce the CPU time, and also get far better network efficiency.

* At 1080p60 the number of channels of decoding possible on Windows should increase when you have a larger number of cores available.

* Lower latency in all forms of HX decoding. This is at least 2 frames better in almost all cases and in many it will be better than that.

* Vastly improved startup discovery performance on Windows.

* Quite a large improvement to codec quality.

* Fix for problem with right clicking when using Scan Converter and KVM.

* NDI now uses predictable port numbers in all cases so that fire-wall rules can be properly built.
- Each connection uses TCP ports 5960 and up.
- Each mTCP or UDP receiver use port 6960 and up.
- Each mTCP or UDP sender use port 7960 and up.

Plugin for Unity 3D (Mac/Windows)

Par : PhilippeC

We released a plugin for Unity that is cross-platform.
It allows the user to share the image from a Unity camera to NDI (or Syphon/Spout if you're on the same machine). It can be used with OpenGL and Metal engine.

Small School Video Distribution System

Good day,
I am in need of a system and I am in need of your thoughts as to whether NDI can assist me.

I have the opportunity to transform my school video playout into something much more dynamic than our present simple video playout system over 19 apple tvs. This is sent out over 4 banks of mini macs to two different "channels". There is only playback capability and people have to run around to the 19 apple tvs when an update of material is put out. I abhor this system and refuse to use it.

I have and want to use CasparCG for play with Vimesh's simple playout program for CasparCG. By no stretch of the imagination is Vimesh's playout simple: it gives a lively feel to the output when you have immediate and on the spot control over what's on all those tvs! In the past, this system has proven to be dynamic enough to keep students engaged in the programming and content of what goes on the tvs.
In trying to use CasparCG, I am unable to get the assists I need to get a distribution tool up and going; my experience is old so forgive me: the ms streaming media server is what I would have had them re-install on our server. Lacking that, I have tried to multicast with UDP.
Our system doesn't seem to be able to do this at the distances I'm working with. Or is configured wrong. Again, assists are something I plan to assertively seek in the next few months. UDP, without a distribution system, isn't going to work.

Before I invest in bucks for all these apple tvs for ndi tools, does anyone know if this will work without a distribution server? And if not, you got one to suggest? I'll even build a linux box for it, at this juncture, as I believe I am on my on on the Engineering side. Got bucks to buy but need to buy wisely.

Your thoughts since you've read this far?

iCaster help

Par : bosk
Hey working on a TC-1 Build# 7-1-19223
just downloaded the iCaster for my iPad, I'm connected using the correct IP, the default layout with the macros work.

My issue now is no video comes through, none of the inputs or outputs at any quality level show up.
I have tried my own layout and still getting the same results of no video showing.

My iPad is running 12.4.1 OS

Does this app still have support?

any tips would be greatly appreciated

New NDI 4.0 version of NDI Monitor for iOS now available.

Par : livepad
Sienna released a new version of the NDI Monitor for iOS today.

The new app adds support for NDI4 sources (the previous version did not support NDI4 sources), NDI 4.0 discovery server, enhanced support for NDI Routing.

The biggest news is performance - the new version has much better performance, and now adds the option to enable full resolution NDI display - provided your device and your network connection can deliver that.

Its a great refresh for a unique and really useful app.

Currently still at the existing v1.0 price - but it will probably increase shortly - so if you don't already have it - there is a heads up.

Now Shipping : Native NDI Intercom for iPhone

Par : livepad
For those of you who always thought NDI would be a great way to do intercom, the wait is over.
Last week, Sienna shipped their new Intercom app for iPhone, which is 100% NDI Native.

This app can listen to any NDI source on your network (not just another intercom handset), and it sends another NDI stream with push-to-talk. Works on WIFI, Wired, and many VPNs over 4G.

The app can be used point to point, one to many and in other ways without requiring any special server. Its available to purchase in the iOS App Store today.

However, If you want something even more flexible, Sienna now has an intercom party-line server module for the NDI Processing Engine which supports the iPhone app (and other sources including DANTE beltpacks).

Revised NDI software Matrix Router/Switcher, with configurations up to 20-in, 24-out

During the summer of 2018 my PC-based NDI software Matrix Router/Switcher has had something of a makeover. The new version (from v1.2) can be configured on start-up to have anywhere from 6 to 20 inputs and from 2 to 24 outputs. Routing Preset buttons store groups of switch positions, allowing multiple outputs to be switched with one button click. Config files can be saved and loaded, including "save last used on exit" and "load last used on start-up" options. Config files include the data for Routing Presets and for the NDI sources used by each input. Multiple copies of the Router can be run, as long as each is allocated a different "base name" for the outputs, which can be done at start-up and is saved in the config file.
