If you're noticing something that seems strange like that I would say do a thorough check to make sure you don't have some misinformation, there's a lot of bunk that goes around on social media. OBS is working but is not fully tested yet: https://github.com/obsproject/obs-studio/pull/2484/ (Disclaimer: I did some of the work on this port)

Wow. I was suprised to read that OBS doesn't work with Wayland. I found some articles [0] on how it runs well using XWayland [1] - which I guess let's you run X-Clients under Wayland - but it seems that the amount of work to get this to work is not trivial, considering the official PR for the work, is on part 3 and that has been open since March![2]. Oh, how did it get so bad? --------------- [0]:https://feaneron.com/2019/11/21/screencasting-with-obs-studi...

You seem to project your own biases on the OBS developers. However there is already work being done for OBS supporting Wayland natively[1]. [1] https://github.com/obsproject/obs-studio/pull/2482

and they get 10k bounties from time to time https://github.com/obsproject/obs-studio/issues/2568 * once ;)

The biggest problem - it doesn't work[1][2] with Wayland. So, for example, with Fedora 32 default installation it is impossible to make it record either whole screen or just a selected window. [1] https://github.com/obsproject/obs-studio/issues/2471 [2] https://github.com/obsproject/rfcs/pull/14

There is a way to capture Wayland https://github.com/obsproject/obs-studio/pull/1758 I'm hoping this eventually gets merged in. This would not only allow capturing Wayland, but also capturing games without affecting the performance too much (similarly to Shadowplay on Windows).

> Or do different OSs have very different strategies for this? Yup. Check out their capture "source" plugins: https://github.com/obsproject/obs-studio/tree/master/plugins... https://github.com/obsproject/obs-studio/tree/master/plugins... https://github.com/obsproject/obs-studio/tree/master/plugins...

Right now there is an open issue about a performance degradation in the last versions of OBS for macOS. https://github.com/obsproject/obs-studio/issues/2841 I don't know if it is correlated to your problem though.

VirtualCam was already a thing, but only for Windows (not sure what is the backstory behind the more recent version being maintained by someone else; I think I'm using catxfish's version): https://obsproject.com/forum/resources/obs-virtualcam.539/ OBS has full desktop as well as window capturing capabilities, so if you only want to show the contents of a single window, you would add a "window capture" item to your scene: https://github.com/obsproject/obs-studio/wiki/Sources-Guide#... ...then select "VirtualCam" from the Tools menu, and click "Start" to start sending images to the selected virtual camera. These virtual devices appear in eg. Zoom, so if you select it and enable video within the app, others will see 5 faces and Visual Studio Code having a conversation. (Of course you can add more sources to the scene, aligning them appropria

OBS will probably be able to do what you want[1]. 1 - https://github.com/obsproject/obs-studio

This reminds me of using OBS to make entirely custom virtual cameras and when Shopify's CEO offered $10k for feature support. https://github.com/obsproject/obs-studio/issues/2568

I found the chroma key implementation, but this seems to assume you have a green screen or similar: https://github.com/obsproject/obs-studio/blob/master/plugins... I thought GP was asking for an implementation of background removal without a green screen.
