Yes there’s OBS Virtual Camera and there’s NDI tools See the setup section here: https://www.hanselman.com/blog/TakeRemoteWorkerEducatorWebca...

Zoom on Windows 10 does not seem to recognize the obs-cam virtual camera. Unfortunately. If anyone has a solution for this, I'd love to get a hint.

didnt work for me either, I had to use NDI tools

If you're running a modern Linux desktop you're probably running Wayland, and screencasts on that have long since been a complete pain in the neck with per-compositor "solutions" that mostly don't work quite right. Fortunately someone who works on Gnome wrote the obs-xdg-portal plugin that should fix this, at least for Gnome and hopefully soon for wlroots and KDE once they fully support the underlying portal API. Unt…

wayland is mega broken on HiDPI. Or at least apps are broken on wayland on HiDPI. Very sad

One thing I wish you could do is have two different copies of an input - in my case, I wanted a video stream input (webcam) where I apply one set of filters to it for one scene, and a different set of filters to another scene. Seems like filters are globally applied to the instance, and you can't have two different scene elements with the same video input device.

I've been using OBS to run a trivia game over YouTube. It's kind of a piece of shit. The Mac port is horrible. None of the widgets work properly, all the menu items are in the wrong place, and it supports essentially no system keyboard shortcuts. Like cmd+F doesn't do "Find…", it randomly resizes the thing you're editing. It's everything bad about Qt apps in one place. It also ships with its own 180MB copy of Chromiu…

I just use Quicktime. Open up a a new video recording, but don't start recording. The video recording window has an option to "float on top" — use that to put your video on your screen where you want it. Then you can either open up a new screen recording (for offline recordings) or just share your entire screen on your favorite conferencing platform.

I also use desktop backgrounds smartly in conjunction with multiple spaces.

>Does Wayland do anything better than Xorg? Nitpick: This is not a meaningful comparison. Wayland is a wire protocol. Xorg is a display server, and the wire protocol it implements is called X11. There are several other display servers that implement the Wayland protocol. Some of these display servers do support those core features, and some of them don't (yet). It depends on which one you're using. The display server…

> easier to develop and maintain wayland may be easier to maintain than X. But from what I've seen writing a compositor for wayland is more difficult than writing an X window manager, because things you got for free with X have to be implemented by the compositor in wayland. And many applications are more difficult to target wayland, because there aren't (at least yet) standard protocols for things like screenshots,…

Take a look at wlroots [0] for a library that massively simplifies the task of writing a wayland compositor. It also gives many of those lower level things "for free". For an even higher-level API built on top of wlroots, you can look at wltrunk [1].

There are standard APIs for screenshots and screencapture, implemented through the desktop portal and pipewire. Check the top-level post for more info about this -- it's part of why Wayland support for OBS has progressed.

Didn't every one agree to use Pipewire for that? Or it's still bikeshedded to death?

Somehow for input, everyone settled on libinput and this didn't become a problem.

OBS is amazing. Half our faculty just went all-out and spent thousands of dollars on some commercial screen recording software. Meanwhile I'm doing my online courses with OBS, and it works beautifully. I have multiple scenes set up in OBS that grab different parts of my screens, and I switch between them with simple key strokes, while narrating on my actions as I do them. It's a very simple, and very effective setup,…

Which OS are you using?

Not OP but I can say that on Windows it may require a lot of fiddling. Hardware drivers appear to be a big factor.

Another concern is the many overlays that accompany game launchers and drivers, including: Nvidia, Steam, GOG, etc. These add latency and sometimes private notifications.

I've been using screen sharing on Plasma/Wayland for a while now and it works absolutely fine. With krfb remote desktop control is also fully available. The latter uses a KWin specific protocol though IIRC as virtual input isn't part of the portal API.

Did anyone report that bizarre OBS bug that Jon Blow ran into while streaming a week ago? It was pretty entertaining... https://www.twitch.tv/videos/575151695?t=00h00m25s

Wish Jon didn't bash so much and contributed to the project instead :(

I use OBS Studio with OBS-VirtualCam [0] to attend virtual lectures & hold meetings for my team. I've found it to be incredibly convenient because you can control nearly everything with scenes and the audio controls. Before meetings start, I can broadcast music and display announcements, and then without having to hit a jarring "End Screenshare" can switch to my webcam and start a meeting. Live demos and presentation…

I'm doing something similar on Linux, although a bit more complicated.

I'm using v4l2loopback [0] to create a dummy video device, ffmpeg to create a stream endpoint that streams into the dummy video device, then setting up OBS to stream to localhost.

It is actually really nice to have the capability to fully control what is going in to the video input.

I haven't run into a need to also change the audio input yet but if it becomes necessary, it should be possible to set up loopback with ALSA.
