I'll try this out when I have some time to troubleshoot. Thanks!

Re: [TCP Send Data format](/topic/5110/tcp-send-data-format)

I found this previous thread with the same situation as the one I'm dealing with.  However, my particular situation is that 0s (zero) are not being transmitted.  It appears that if the parameter is a value of zero then it is just skipped.  (I need the zero to be included to preserve the expected message format on the other end.)

I have reduced the situation to the very simple example below.

In the above example, parameter 1 and parameter 3 are transmitted as the anticipated values.  However, parameter 2 is skipped - the zero is not transmitted

If I use any of the other available formats in the "TCP Send" actor I just get the ASCII representation of a zero and not the value zero.

What am I missing?

I eventually want to stream 4k, but this is more to do with the bandwidth of the various platforms rather than any Izzy issues.

You should chat with the folks at Office Hours Global. They're always pushing the limits of what's possible when it comes to broadcast and streaming. I've been hanging out there for years and they're all super knowledgable and friendly.

*not actually GoPro, but I used a FLIR C5 thermal camera recently, connected via USB extension, and it showed up as a Video source in the Live Capture Settings menu. Which was nice.

By default Projector actors are not connected to each other at all. If you want to have the same mapping in all of them but be able to adjust different inputs on them, you should wrap a Projector actor in a User Actor and add User Inputs connected to the inputs on the Projector actor that you want to be individual to specific Scenes.

See this video tutorial about Isadora User Actors for more details.

Thanks so much for your suggestion — I’ll definitely give it a try. At the moment, I need to keep the system as simple as possible. It’s an interactive installation using Arduino with heartbeat sensor detection. I use GLSL to overlay waveforms onto a large selection of movie files, which are then re-captured and reloaded into the installation. The system must auto-load and configure itself each morning. The audio has its own separate routine: by counting the number of re-captured videos, I’m able to trigger a beat sound file once a saved waveform overlay clip has been recalled.

I truly appreciate your help — I’d definitely like to explore using Pythoner in a future version of the patch!

am I running too many concurrent sounds

How many Sound Player actors are you actually running at once? More than 16? If you look at the help text for the 'sampler chan' input of the Sound Player actor it says:

"The sampler channel on which the sound will be played. Isadora has sixteen audio sampler channels, numbered from 1 to 16. Set this value to 0 to play the sound on any sampler channel that is not busy playing another sound. If you attempt to play a sound on a sampler channel that is busy playing another sound, the current sound will be stopped before the new sound begins to play. If you play two sounds on two different sampler channels, then both can be heard at the same time."

(If you left the 'sampler chan' input on all the Sound Player actors at the default, '0', then you can ignore this paragraph.) If you specifically set the 'sampler chan' input on any two Sound Players to the same number, you could be running into the issue in the second underlined sentence above. For example, if you had a Sound Player for a looping sounds set to 'sampler chan' = '2' running, then triggered a Sound Player for the thunder that is also set to 'sampler chan' = '2', the looping Sound Player would stop. 

If you have any looping sounds that don't need complex audio routing you could also save them as .mp3 files and play them using Movie Player actors to avoid hitting the sound sample channel limit.

Alternatively, if you are hitting the sampler channel limit but need full multichannel audio routing capabilities, you could copy the Isadora application, run two versions of it, and use a Net Broadcaster actor on in Patch A (Isadora application #1) to trigger sounds via Listener actors connected to Sound Player actors in the Patch B (Isadora application #2). I'm not sure whether that would work, but it's simple enough to try.

Another option might be to run your looping sounds combined for a long time while using OBS to record your computer's audio output (or record a video with computer audio then convert the video file to an audio file), then use that longer loop of combined sounds in Isadora played through a single Sound Player actor to reduce the number of sampler channels you're using simultaneously.

Obviously I don't know enough about your use case to say which idea would be the best to try first, or if you even need to try any of them, but I just wanted to point out that there might be some possible solutions if the issue you're hitting is maxing out the sampler channels.

@mark_m, thanks for sharing. I have circulated this around to a few people. Cheers.

@citizenjoe

Perfect. We have identified the issue. Thank you for the feedback!

@DusX

Hello I'm trying to find a way to project my canvas and particle based code from p5.js via Isadora.
From what I read in the forum it's not possible to project with Isadora's javascript actor. Does anybody happen to know another way to showcase/project the code? Thanks in advance for any further help :)

Is there a way of having each scene send a body of text notes about the scene to a window in the control panel, updating with each scene change?

@armando

I've tested it and you can control it using the PTZ image control when connected over USB-C.

I must admit that i never connect the Obsbot and always use it wirelessly and control the camera using the app or OSC.

@thatmattrogers

What you did is probably how I would do it.

Could you please send in a ticket using the link in my signature with a screen recording where you show Stage Setup and more clearly narrate and show the roadblock you're hitting within the keystoning? I get the general idea, but I want to understand more precisely so that I can accurately log this as a feature request.

Hi

I am just chiming in with my 2cents. I have been in this position and trying to sync video with external audio. There was no real way to do this nicely as the audio will stutter etc.

Upon asking here about 6 years ago, I followed the advice and edited the video(s) together so it is just one "super" video. 

Easiest way to do it even if it requires setting aside some editing time. Your edit is not a big ask and it is the simplest way out of your issue. 

Kinda the only way to ensure sync tbh.

- Have you noticed (or at least in my case) that if you draw quickly and furiously, certain glitches appear, like sharp lines that break or interrupt the stroke?

 Yes, we're aware of that

Has anyone had any luck getting VOR to hear MSC commands from Isadora?

It seems to stay "...waiting"

The sensor lights red (connected to power source and via hub, because this Mac model doesn't have an internal standard USB port) Status output unit in OpenNI BETA actor says resolving uri. I tried to download the Kinect-test-macOS folder, found in the forum, but cannot run it because of security. I'll be very happy to hear a suggestion from you.

 Sometimes the order and configuration of things matters for finicky hardware like the Kinect, for example you can try:

Launching Isadora then plugging in the KinectQuitting Isadora, plugging in the Kinect, then launching IsadoraPlugging in the Kinect, restarting the computer, then launching IsadoraNot having the OpenNI Tracker actor in the very first Scene of your file so Isadora finishes all startup processes before you move into a Scene with the OpenNI Tracker actor.Trying with an unpowered hub (avoid putting anything else on the hub)Trying with a powered hub (avoid putting anything else on the hub)Trying with a USC-C converter instead of a hub (this is what I would personally recommend because it removes all the variables that come with using a hub)

You get the general idea, trying things in a different order or a different configuration sometimes has different results when it comes to hardware-specific issues.

TH2go seems to only display as a single screen

As @Skulpture wrote, this is the expected behavior. It's for Isadora 3, so the exact names and appearance of things might have changed from what's in the article, but the general information/idea explained under the heading "For users working with a Matrox TripleHead or DualHead only" in this support article of ours about working with multiple displays might still be helpful to you.

I've also just logged this in our issue tracking system.

@tim_f Hi, ah, I just realized the frequency band actor works with the default mac device, not with a variable audio input. But you'll find quite some actors with audio input in the audio category of the actors list, such as all or most actors starting with AU on macOs, they come from the default Core plugins, at least on recent macOS versions), as well as audio plugins you might add yourself to your mac sytem (for example through the MPluginManager - opens quite a big range of possibillity). 

For example, I had a multichannel video and wanted to manage the gain and routing of each sound channel in Izzy. The movie player doesn't allow that, but using Blackhole as device for the MP and as input in the AU Input actor, I was able to do pretty much anything I wanted to the video´s sound. Have fun with that! 

Best,

Jo
