obs virtual background linux

The Linux version of Zoom only supports background replacement via chroma key. I don’t know how to solve that problem and I don’t have a good alternative on Linux.

日本語 There seems to be very little documentation on doing this server side. I don't want my screen recording only to show up in my _webcam_ view, which is usually just a tiny thumbnail. The first obvious step is to smooth the mask out, with something like: This can help a bit, but it’s pretty minor and just replacing the background While Zoom doesn’t seem to have commented anywhere about how they implemented The problem is that v4l2loopback only provides a virtual _webcam_ (video source), not a virtual _screen_ - the two are different and are handled differently both by browsers (webrtc) and desktop conference apps (Slack, Teams, etc). Amusingly I did some hacking on this and the current bottleneck is actually reading from the webcam which is capped at <10fps without doing anything else. Pytorch has Deeplab available on their hub (I'm sure TF has something similar). After installing FFmpeg, install OBS Studio using: sudo add-apt-repository ppa:obsproject/obs-studio

I followed the instructions at https://github.com/umlaeute/v4l2loopback to install the video loopback device. In my case, the primary advantage was that this virtual webcam is streamed in Jitsi Meet at a higher quality/framerate than the regular desktop share feature. You can usually alter performance (with Bodypix that's an accuracy/speed tradeoff) or do something silly like downscale, run, and upscale the mask. And now we can see that our camera works. This is exactly how it worked in Photo Booth on OS X over 10 years ago. Return to OBS Studio, then edit the camera in your scene to re-select the physical webcam device. while our OpenCV operations are in BGR (blue, green, red) channel order. After discovering Linux back in the days of Mandrake in 2003, I constantly came back to check on the progress of Linux until Ubuntu appeared on the scene and it helped me to really love it. sudo apt install obs-studio. It's just a matter of suspended/delayed deliveries and state orders to avoid unnecessary travel--including shopping for things like home furnishings. It's a bit fiddly to get working, true, but it's a tick box thereafter, which is really nice. The bit I was missing was how to create a virtual webcam.

Beautiful hack.

I also suspect Zoom prioritized resolution (for content clarity) over frame rate for screen sharing, which probably doesn't apply when it's just a "webcam" in the eyes of the client.

A modern laptop will run Bodypix at about 30 fps. The web requests are just an easy mode of IPC to pass around some bags of bytes, "high frame rate" is at most 30 qps ... that part isn't really interesting performance wise and this isn't a production tool :-), I'm not sure I'd be so confident about tensorflow.js being so fast on the CPU ... you can see a marked difference in the backends httpss://www.tensorflow.org/js/guide/platform_environment. Or can i do teh same with on obs studio? Cam is the basic 1280x720 Microsoft Lifecam USB webcam I've had for years but is still much better than any laptop cam due to placement flexibility and better optics. I’ll definitely be joining all of my meetings this way in the morning. If not so can i install obs-virtual cam on linux? [2]: https://pypi.org/project/virtualvideo/. controversially become very popular. OK, now that we have a video feed, how do we identify the background so we can Some time ago I learned about OBS Studio, but it presents a steep learning curve and it took me quite some time to find the energy to sit down and start climbing that curve. Hey, I saw a new video device at /dev/video2! cropping it to a 16:9 ratio image …. IIRC it's something like 10FPS currently which is sufficient enough for meetings so far (about 1/3 what you might get with sufficient bandwidth in most video conference tools). I mean...in fairness I could probably figure out how to get hold of a sheet (seriously, of all the ugly colored sheets and blankets they sell at the local Target, there isn't a bright green or even blue??). replace it? I dug out an old USB audio interface I had packed away and tried it with a Shure vocal mic, but that led me down another hole of messing with Voicemeeter to tweak EQ and noise reduction because it's really meant to be held right up to your mouth (for singing, etc) and picks up background noise if I have the levels up high enough to use as a desk/stand mic.

The background images can have a big impact on how good the green screen effect works. Doing it on the client could theoretically save bandwidth, if the background was a changing scene.

I live where programming meets the business. This also lets lean into blurring the mask.

Chroma keying is the stable version of this idea: the single background color of a separately and well lit background removes these issues. The demo at the end of the page is a video (webm), but there's not a ton of motion to reference besides the blinking. Awesome stuff Ben! It seems like moving all that data backwards and forwards between Python and Node might be a bottleneck, no? This reminds me that I was going to write an article on this. If you do not have the FFmpeg installed (if you’re not sure, then you probably don’t have it), you can get it with the following commands: Then you can install OBS with the following commands, make sure you enabled the multiverse repo in Ubuntu’s software center (NOTE: On newer versions of ubuntu adding a repository automatically apt updates. I followed the instructions at https://github.com/AndyHee/obs-v4l2sink. Linux: Fixed an issue where the browser source could crash when browsing files, Linux: Fixed an issue with “always on top” sometimes not working with projectors, Linux: Fixed an issue where cameras using V4L2 would not respond correctly to pan/tilt controls, Linux: Fixed an issue where a user’s preferred language could not be detected correctly, Fixed camera controls on Linux video devices not working. I was fortunate enough that the previous owners left behind a god-awful teal paint that works amazingly as a ‘blue’ chromakey. First create a requirements.txt with our dependencies: And then the Dockerfile for the fake camera app: We’re going to need to install v4l2loopback from a shell: We need the exclusive_caps setting for some apps (chrome, zoom) to work, the label I tried it and it worked!

Português do Brasil At the same time, I'd assume the inference/ML part is the fastest one, because, as far as I understand how NNs work, they're supposed to be blazingly fast once trained (it's just lots of parallelizable linear algebra).

webcams. If you do not have the FFmpeg installed (if you’re not sure, then you probably don’t have it), you can get it with the following command (or compile it yourself): First, make sure you have everything up-to-date. Given that we’re using a Star Wars “virtual background” I decided to create Also available as a Flatpak package on Flathub, otherwise head here for other distro downloads. to use the loopback as the conference presentation.

I’m dialing into the millenium falcon with an open source camera stack! This means that after I start OBS Studio, my Virtual Camera device is running and I can use it.
