Matrix-webcam displays your webcam video feed in the console

[dhosek]

Not clear—can I use this for my outgoing feed so that people will see me as an undulating collection of monochrome characters in the conference?

[nonoesp]

The README says you can pipe this "matrix feed" to Zoom by using OBS Studio's Virtual Camera feature. I've used this virtual camera on Zoom meetings before and, especially on macOS, it can be laggy.

[joschuck]

exactly, see the README on how to do it. I am not taking responsibility if you do it with HR though

NICE! and way cooler than what I did; i too went the python - obs - virtual device route, but to have my randomly hued face pingpong around the screen like the dvd logo screensaver

Very cool stuff!!

[tobtoh]

I've been playing around with OBS and Zoom lately as well. Prior to a meeting, I pre-recorded a couple of minutes of me watching the screen. I used OBS to switch to this looped pre-recording whenever I wanted to eat/drink or get out of my chair to stretch etc during the meeting.

It was mostly just to satisfy my curiousity on how difficult it is to do (it's easy) and whether anyone noticed the looping (no one did). But what I did find interesting was that I found it immensely 'freeing' to be able to participate in the meeting without being observed - there is something about knowing I'm on camera that I find taxing that I don't get in a face to face meeting.

That sounds like fun too! Did you put it on GitHub yet? And if not, then please do :)

For anyone who wants to play a whole movie matrix-style, with audio, you can use aalib with vlc as a video output:

If you're extremely patient you can do it manually :)

Looks like a fun tool. On macOS, it always does an 80x24 display, no matter the actual size of the display. This make is low enough resolution that nothing really useful is resolvable. Tput has no issue determining the console size.

[boston_clone]

You might be able to refactor line 76 in __main__.py to use larger values than the default terminal window size? caveat emptor and all, since I haven't tried this myself.

Ah, I see, webcam selection is not available, so it pulls-up my laptop's in-built one (I think) and not the one I have connected on top of my monitor, so I just see some noise from the closed laptop. Looks fun, though.

Looks like a one line change, change 0 to 1.

[joschuck]

oh it's even on the todo. Let me add that in a bit

[danpetrov]

Nice! Although the naming could be a bit better, because I cannot be the only one who thought that this has to do with https://matrix.org

[symisc_devel]

A similar transformation can be done on ASCII Art at Real-Time using a single decision tree:

It's impressive you can do this in 200-odd lines of Python. How much CPU juice does that SelfieSegmentation drink?

[joschuck]

It uses mediapipes selfie segmentation module: https://google.github.io/mediapipe/solutions/selfie_segmenta... using MobileNet v3 (around 0.5 GFlops of juice it's gurgling, so enough to run on a raspberry, maybe not your Casio)

At my work, I'm making a media player to rule them all, including with live streaming via WebRTC. I only work on the front-end portion but Javascript and the browser now need absolutely no extras to perform live streams.

[CSDude]

Here is a simpler one I made 10 years ago with few lines of Python using OpenCV which runs very slow though. https://github.com/mustafaakin/terminal-webcam Not very matrix like though.

[tapoxi]

Wow the setup for Linux seems to be painfully more complicated than macOS/Windows. Why is that the case?

[laumars]

You can follow the same steps in Linux as you did for macOS too (OBS is also available for Linux, in fact that how I personally run OBS).

The reason the Linux instructions are more verbose is because Linux also supports writing directly to a virtual camera via the command line. Something that’s not so easy to do with macOS. So you can save yourself a lot of lag and system resources by doing so rather than using OBS.

[insulfrable]

... he asks, rhetorically.

[marginalia_nu]

Yeah for whatever reason webcam tooling on Linux is really dismal.

[lightedman]

Is there any way you can make this into an installable plugin for OBS for Windows users? I'm no programmer by any means, so making this work as-is is a no starter for me.

[joschuck]

Of course you could, but that would be for a different project. The goal here was to have it in the terminal. I you just want it try this: https://jeeliz.com/demos/faceFilter/demos/threejs/matrix/

[daoist_shaman]

Why does this have to be ASCII art? Is there a technical limitation to terminals that prevents the full color space of the video sensor from being rendered?

[kennyloginz]

Ha, this is great, thanks! Wish I could take it back in time to when I was interviewing with multiple static gifs while being broadcast live.

[sodez117]

Looks cool. Anyone knows if there's a similar project for webcam privacy? Kinda like "salting" the webcam feed

[renewiltord]

mplayer with aalib worked surprisingly well for video playback this way back in the day

[7v3x3n3sem9vv]

it's why my name is like this

[bloopernova]

Fantastic, love it!
