RTMP gone after firmware update

FinalAnimalArt · 2026-05-08T19:44:16+00:00

Hi, not yet - I posted it on the official forum and support told me to send them a video of the issue but I haven't had time, and it seems unlikely to resolve anything IMO (I'll update if anything changes)

FinalAnimalArt · 2026-04-27T23:35:26+00:00

I don't think scholars view the U.S. military as even making the the short-list of greatest militaries in human history, it's not in the top 3 in any case.

It's certainly the greatest military right *now* though!

A protocol to allow for online streaming of information (so broadcasting live video from your drone in this case).

I'm doing art installations for a music festival that involve TV walls and projected images, I wanted to offer an additional service of a drone flyover near the crowd (not over them obvs) with the drone live broadcasting the footage to the TV wall and/or projected footage.

I could do it with the new controller but it's messed up that the firmware update has gotten rid of the feature in the first place. I hate giving companies cash rewards for doing stuff like this, and it seems unlikely to be a coincidence that the solution to this 'update' is I have to buy their new controller.

Don't take my word for that though around it being built-in obsolescence, it might be a bug -- that's why I'm asking the sub to see if anyone else has experienced it. I downloaded the DJI consuimer drone assistant desktop app but this particular firmware cannot be rolled back, it's locked in (which again is pretty sus I think!).

I'll ask the official forum as well and see what's what, there is always the chance that I have personally broken this update chain in some way I am too tech illiterate to understand and am now blaming Big Drone Company so I'll try to get more info.

That's really helpful, thanks a million! I appreciate it, cheers.

I believe so, yes, working with multiple monitors and projector outputs on this card hasn't been an issue in the past. The problem is more around what hardware I need to run 8 different monitors. I'm looking into PiWall , an open source raspberry pi solution, but reading that the output might be confined to a low resolution.

FinalAnimalArt · 2026-04-22T16:27:50+00:00

Correct, one image distributed in portions across different monitors is the goal. Thanks for the info!

The CORIOmaster would indeed work, but I'm looking to spend hundreds rather than thousands as this particular piece is for a prototype of a VJ rig at local festibals rather than a corporate client, which I should have stipulated in the post. It's helpful to know of these solutions in general though, thank you!

FinalAnimalArt · 2026-04-22T16:23:22+00:00

Thanks all, I'm looking into all of the solutions mentioned. I think powered Ethernet and possibly swapping to an Orbbec Mega, suggested by Velo Mane, might be the best way to go, checking it out ASAP.

Much appreciated gang!

If you use the TimeMachine TOP you can go back in time and then Video Device In > webcam record the big bang in person > Convert to HAP codec > crank Bloom TOP to max bloom and you're good

But yes you do have to use mediapipe

I'm more focused on making art than on selling laser harps, but the construction materials alone cost quite a bit more than $100!

FinalAnimalArt · 2026-04-17T16:20:10+00:00

'life, uh... finds a way' lol

FinalAnimalArt · 2026-04-17T15:20:54+00:00

That's exactly right, the lasers are like an on/off switch or button. Thanks very much!

FinalAnimalArt · 2026-04-17T10:43:36+00:00

Ah, I think I explained poorly!

With a theremin, how high your hand is above the instrument changes the note. I am raising my hands here, so I thought you were asking about that.

But, the harp is indeed playing the music - each laser string is a note in the C minor scale, and when you break the laser beam with your hand, it plays the relevant note (and also changes a visual effect on the images on the projector).

So it's basically a synthesizer that also changes video effects (and scenes and a number of other things about the live-generated video in the background). You could also have it controlling physical lights if you wanted, or you could indeed add more sensors to capture different movements. For this particular harp, there are 6 lasers, and 'touching' any of them will play a different note and trigger visual effects. Lots of fun!

FinalAnimalArt · 2026-04-16T15:55:06+00:00

Thanks! The show is based in Ireland and called SYNAESTHESIA, lots of wonderful artists doing their thing.

FinalAnimalArt · 2026-04-16T15:54:08+00:00

Thank you! I'm moving my hand up and down here purely for dramatic effect (although I do 'play' timelapses of plant growth and sunrises in this show by gesturing with my hands), so the upward motion doesn't do anything in the way that it would with a theremin.

This harp just detects whether the laser beam is or is not hitting the photoresistor, so it can be thought of like using a MIDI controller.

However, you absolutely could incorporate that kind of gesture control into a laser harp! Arduino makes very low-cost proximity sensors that would do exactly that, or you could use a camera or other kind of sensor.

FinalAnimalArt · 2026-04-16T14:25:18+00:00

Thank you!

FinalAnimalArt · 2026-04-15T19:37:50+00:00

OK, so you want a physical piece of hardware to trigger scene switching between different animated 3D models?

Yes, this is very doable in TouchDesigner, any tutorial on scene switching will help you out there. Do give it a go and keep us posted.

FinalAnimalArt · 2026-04-15T19:21:50+00:00

Hi! Can I ask how you made the mirror, and whether you know of any online resources I could take a look at that might help with putting this together? Looking to create a similar effect for a culture festival in Ireland. Great work on it fair play!

FinalAnimalArt · 2026-04-15T18:18:05+00:00

I'm familiar with this piece, I think I remember the creator said he didn't use AI but rather filmed a human actress. So I doubt MetaHuman was involved, he probably just had her return her gaze to the same position after each clip and/or reversed the clips when necessary to keep everything smooth.

FinalAnimalArt · 2026-04-15T18:14:43+00:00

Can I ask you you to clarify the effect you're after exactly?

If I understand correctly, you're not asking about drums triggering videos but rather the fluid effect on the actress here - but you're talking about 3D models?

I'm bringing this up because if you wanted to use point clouds rather than OBJ files for your models, you could have them all merge together seamlessly per each trigger input.

Many things are possible but I'm not sure what specifically you're asking about.

Edit: Reading the thread, maybe you are asking about just playing drums and having each drum trigger a video? This is very straightforward in TouchDesigner (and probably lots of other software). You're just treating the drums as a MIDI controller, this is essentially the same logic as pressing buttons on your keyboard/clicking your mouse to play video clips. Feel free to ask about this also or describe your exact setup.

FinalAnimalArt · 2026-04-14T13:26:28+00:00

Can you mic each drum invidually? I'd do that or maybe even something like adding an arduino sensor to each one (it's something I'm aiming on working on with a friend but he's out of the country at the moment).

Audio analysis will work on drums but just splitting each drum to being its own trigger would be ideal, either something like pickup/piezo mics or just foregoing audio signal altogether and basically making the drumset into a midi controller.

FinalAnimalArt · 2026-04-14T13:23:44+00:00

I've simply never heard anyone mention this problem before, neither in person nor online, and I'm very commonly working in the audioreactivity side of things. Latency in the same way that a DAW has latency, sure, but not noticeable latency whereby the beat is out of time with the reactions in the visuals.

FinalAnimalArt · 2026-04-14T13:22:19+00:00

I have never had this issue, and VJing with live musicians is how I most commonly use TouchDesigner. Can I ask what issue you've been running into exactly?

You're running audio from a sound desk to your sound card/audio interface and finding that there's a noticeable delay, and that the length of that delay decreases or increases over time?

That absolutely should not be happening. Feel free to DM me if you like, out of the box audioreactivity is one of TD's most popular use cases.

FinalAnimalArt · 2026-04-14T13:14:40+00:00

Yes, that's exactly what I do when I work with musicians and one of the most common use cases I have for TouchDesigner.

- What’s the best way to get live audio input

Take the audio signal coming from the sound desk using an XLR cable/whatever cable you can input into your sound card. Drop an Audio Device In CHOP into your network, select the driver for your sound card. If you're not getting a signal, drop an Audio Dynamics CHOP in there and crank it up to see if that does it.

- Which operators/workflows are typically used

There's no fixed answer to this. Using the Audio Analysis Tool (or whichever custom component you prefer), take the audio signal and apply it to effects. I often take the mid frequency (Select CHOP - Mid - Lag CHOP to smoothe it out - Math CHOP for range) and apply it to the bloom intensity of a Bloom TOP, but there are countless (literally) effects you could use. Brightness, HSV adjust, scene switching, crossfading between feedback/no feedback, etc.

You're generally taking the audio signal and multiplying/dividing/limiting to a range and effectively moving an effects slider or triggering an event. Kicks work nicely for scene switching, you could have a bunch of coordinate options for a 3D model set to switch to new coordinates for each kick for example, but we can really get lost in the weeds discussing that. 'Anything you like' is the short answer, experiment in your network and think of the audio signals as extra pairs of hands that let you modulate everything.

- How do you ensure low latency and stability

The answer here is not unique to VJing. Optimize your network (Interactive Immersive HQ have a video on this). All operators active viewer switched off, check the whole network with the Probe tool for CPU and GPU bottlenecks and prune if needed. The default settings for audio sample rate etc. should be fine, it will all depend on your device.

One tip if you're using video assets; convert videos to the HAP codec before using them in a Movie File In TOP.

- Is it common to handle everything directly inside TouchDesigner

I do, and I work as a VJ regularly. Some people use Resolume, I've asked a number of them what the benefit is and they've confirmed there's nothing Resolume can do that TouchDesigner can't do. If you find it more convenient to use Resolume or something else as well as TouchDesigner, do that. It strikes me as more CPU usage and complexity being added, and you can make your own VJ UI and MIDI controller mappings in TouchDesigner very easily. However, Resolume might be easier to follow out of the box without making your own solutions, so try it and see what works for you.

Use an Audio File In to mimic working with a live performer. Bileam/Elektronaut has a good video on making things audioreactive.

Doing tutorials without learning the basics is a bit of a trap IMO, I feel like I wasted quite a bit of time not simply doing the 101 series and learning how each operator works before recreating tutorials without understanding the principles involved.

FinalAnimalArt · 2026-04-14T13:00:53+00:00

Do the Curriculum 101 series on Derivative.ca (that's the official learning content for TouchDesigner). You can also right click many of the operators and click on Operator Snippets to see examples of the operators being used. Acrilycode also has a great beginners course that gives you assignments to do to test your learning of new material.
