As my colleagues already touched on. Each single stream would need their own unique ID.

Marked this post as answered, if you have any follow-up questions please feel free to ask :)

Am I correct in assuming that Isadora receives sound from an NDI source

 The NDI watcher actor only captures the video feed supplied by the NDI feed. A future version of the actor may provide the audio feed as well. We are working on extending Isadora to offer broader audio support. You can expect to see the Multi-channel audio routing currently available in the Sound Player actor appear in more actors as we move towards Isadora-wide audio support.

I just had a similar problem last week while trying to send NDI and OSC to and from a powerful Windows show computer that belongs to a university that has very strict network and computer security protocols. I never did figure out what setting on their computer was preventing it, but when I hooked up two non-university computers to a network switch I was able to send NDI and OSC back and forth without issue. I suspect it was a firewall problem, but nobody around had sufficient security credentials to do anything to the firewall's policies regarding Isadora on the university computer. So maybe check your firewall settings on both computers? Also, as a test, I'd hook up a third computer to your network switch and see if it can send and receive NDI to and from your original two computers. This test might help you identify which one of them is the problem.

Thank you so much for your answer, I've been trying and testing some things and your suggestion of testing Isadora to Isadora was very useful. there seems to be an ndi compatibility issue between touchdesigner and Isadora or something. right now I'm using syphon on the Touch macbook to get the visuals into Isadora and using ndi to send it to the other computer.

So syphon Touch > Isadora gives smoother results than using NDI it seems.

Hope this helps others as well who run into this problem

@j-grima

Please go and download the NDI Watcher from the add-ons page: https://troikatronix.com/add-o...

This add-on will allow you to connect to multiple NDI sources.
This is the preferred method in Isadora, I would not recommend the NDI virtual input, unless you need to use it for specific reasons.

@mark many apologies for this extremely late response.  I got caught up in tech and then no longer had access to the systems where i was running into this.

Current tests with Mojave and the latest NDI Watcher 1.0.1 -

NDI 4 Watcher 1.0.1 on Mojave Isadora 3.0.8 reports correct resolution

NDI 5 Watcher 1.0.1 on Mojave Isadora 3.1.1 reports correct resolution

in brief test, all is working as hoped!

thanks so much

ZoomISO is now fully available! Big thanks to all of the Isadora users who helped us test the beta.

I have done that in a past life (4 years ago) when I was using TCP Syphon to send video signals to RPI 1B+ units.  Unfortunately, my current receiver setup (https://dicaffeine.com/ running on a mix of RPI 3B and 3B+) don't have that capability.  The units are already at 75-80% CPU just decoding the SD NDI streams and the software doesn't support cutting things up.

Another option I am consider is forking my network and playback system into two layers. A master Izzy playback computer would send 2-4 NDI streams containing half or quarter of the wall's imagery to 2-4 matching second tier Izzy computers over network A.  The 2nd tier computers would then cut those images up and pop them out to all their respective RPI receiving nodes over network B.  Maybe a little crazy?  Maybe could work?

thanks everyone for your replies. ndi and yams work indeed. much appreciated. however i am still kinda intrigued about the sidecar option because it actually semi-works.

here are two screenshots for the same file with the macbook and ipad connected via sidecar but different screens assigned as "secondary". when the ipad is assigned as the primary screen or "display 1", everything works smoothly, I can use my ipad as my main display and control the scene while the  macbook screen is used as the second display.

case one : workswhen ipad is display 1 and macbook is display 2

however, when the ipad is assigned as the second display, the ipad screen turns white instead of displaying the stage it's assigned with. 

case 2- not workingwhen macbook is display 1 and ipad is display2

sorry if this was already clear, but I wanted to make sure that I was able to explain the problem. i'm risking repeating myself because it seems to be a minor problem that might actually be a bug that could be solved with a tiny little patch?

I begin to understand the power of activated scenes ;-)

 You can also use background Scenes to make global projection mapping easier: https://community.troikatronix.com/topic/5495/global-projection-mapping-simple-show-template?_=1613735987660

I will be very curious to see if these SAM technologies as well as the shared memory layout of the M1 make their way into NDI and live video pipelines in the near future:

Just want to thank you all again for all your help and insight. We're opening our show tonight, if anyone is interested in viewing the piece you can stream directly on our Twitch! We have two showings, tonight 20:00PST (Vancouver/LA time), and tomorrow (Sunday) same time. 

Fingers crossed that Skype continues to behave for us! All of your tips and suggestions have been immensely helpful. 

Grateful always for you all!

@dusxI I have actually done just that now. I did test sending directly from my system over a hardline into a capture card for the streaming server. I then tested setting my stage output to spout and using Spout to NDI to send the feed via network to the same streaming server. The Spout to NDI handled things the best just slightly. Which I found surprising. 

@woland

thanx for the tip!

Explored some more and got some feedback for everyone (still working out the kinks but figured I should report back).  I am currently using VB Virtual Cable which allows to connect virtual sources. I selected the virtual cable on the  audio out field in the NDI Watcher Beta and then selected the same virtual cable in the live inputs. This allowed me to bring the audio from the individual NDI sources to the live inputs in Isadora. Still a few kinks (the separation between the various sources is tenuous because of audio feedback and the responsiveness of the connection requires a couple of restarts) but definitely a work around!

Recovering Isadora 3.07 has been a big help in trouble shooting the stream setup to Blackboard Collaborate. I am still getting intermittent black video where it appears the stream is previewing in the Live Capture Settings but not then displaying through the Video In Watcher. After trying to pin this down, I think it requires a specific sequence of activation steps to maintain the through put of the video. I tried a bit harder with direct audio through the camera and can only conclude that Blackboard Collaborate is noisy and without a convenient way to monitor the audio stream before going live. I did manage some improvement by recording the stream and playing it back-that appeared to be the only way to know what the stream sounds like. Anyway after setting the sensitivity of the Senhieser radio transmitter to -24db I was able to reduce some of the noise. Monitoring audio through the camera sounds fine and through Isadora sounds fine, so my conclusion is that Blackboard Collaborate does not handle audio that well. But I will keep trying to get clean audio.

I am hoping to get the video and audio stream to run through Isadora, and I will keep trying to get a stable patch configuration.

Best wishes

Russell

Does this mixer allow you to get video into the Live Capture Settings using the Blackmagic driver? Or????

And in Windows it's the same: the ATEM input is seen as a Webcam in Isadora, and you just set the driver to Windows NOT Blackmagic.

@django Nice work! Thanks for sharing your process.

You could use OBS.Ninja instead of Skype?

@vixmedia Not at all! ZoomOSC extends the vanilla zoom client, so you just log in using your official Zoom account and the software will inherit whatever privileges you have in your existing Zoom account. Now, depending on the type of work you are doing, having a paid account might give you helpful features like webinars or multi-person meetings over 40 minutes in length, but we don't impose any requirements on account level ourselves.
