NDI Source for live video IN/OUTput & matrix model

Hello everyone.

In few words:

-The ability to use an NDI IN source as a template to play for matrix animations.

-The ability to use an NDI IN resource as a video inside QLC+

-The ability to output videos and the result of the animated matrix model as an NDI OUT source.

Thank you very much. I await your reply.

And will the subsequent request be to pixelmap to the NDI input stream?

I'm very keen for this

For those who do not understand Fredjes remark: If you want to play a HD video in RGB colors on a RGB Matrix, you will need 1920 x 1080 x 3 = 6.220.800 DMX Channels (= 12.150 universes).

Hello.
Exact. From what I understand, moving the fixtures in the "monitor fixture" window in 2D mode can create a kind of mapping, but you don't see the visual part as a reference behind the fixtures. This can be a bit confusing.

Also now going further into the matter I noticed that uploading an image file not being able to change the mapping, size of the image or its rotation the final result is not correct.

Example:

I had hypothesized to do a mapping moving the LED matrix in the monitor fixture section but it turned out to be a very difficult/impossible thing.

Youtube video links in which I try to do the latter:


I read MichelSliepenbeek's answer and I understood it to some extent.

In any case, here's how the Resolume arena software handles the issue even with a 4k video, but using a few fixtures positioned at key points.

Example Resolume arena:

Not exactly,
You define some pixels in the image and can bind your fixtures to those pixels. When the video stream is interpreted, the fixture follows the color information of the underlying video stream.
Compare it to the Phillips ambi-light kind of thing.

Please do not suggest to copy-cat functionalities present in other software. There is something called a copyright. If you think the other software is what you are after, use it and pay for the license.

Okok.

From what I perceive from the answer, rightly so. You're taking this very seriously. Ok. I tell you for my part that I have no intention of breaking any rules. But I saw in that software an interesting feature that QLC+ could be inspired to implement a new feature. I have cited the source of the software for security. Then of course, not being an expert in all bureaucratic issues, I don't know some things.. And in fact for those things I expect that the relevant professionals intervene.

I hope my point of view is clear enough. that is, to be inspired and not to copy.

Then I have to say that this speech seems a bit strange to me. in the sense for example: let's assume that QLC+ lacks the functionality of creating a CUE/Scene. but in Resolume Arena, GrandMA, freestyler there is.. and I write a dedicated post to suggest to Qlc+ to implement a feature that exists in these softwares. if QLC+ implements it, I don't think it's infringing a copyright. but it's implementing a basic technical mechanic. (of course.. without copying the visual design of those software.. of course). Beyond the example... QLC+ the thing about creating CUES and scenes has it.

I hope my reasoning is clearer.
Greetings.

This guy is working on a screen grabber:

Give it a try on the screen grabber branch

Thank you Yestalgia.

Sorry but I'm not very familiar with programming issues and I have no idea how to use the resource you shared with me (at the file level).

There is some instruction or video tutoring that shows how to use this type of material?

Thank you <3

Just wanted to point out that there is plenty of software beyond Resolume that can do pixel mapping from a video source (ELM and magicQ to name a couple) — there's nothing proprietary about the idea - software ideas in general can't be copyrighted. There is absolutely nothing illegal about copying an idea from another program as long as the feature isn't under patent (this one isn't), and you're not copying things that actually are copyrighted (images, extended bits of text, etc.). I'm not aware of any free software that can do this so it would definitely we a welcome addition.
