Show HN: X11 tool to share a screen area in any video meeting

Do I understand correctly that you could to this with OBS on any platform, including Wayland? I'm reading many comments that make me think either many people don't know about OBS, or I'm overestimating it's abilities.

You probably can. I never used OBS, but it's probably a bit more than a 20kb binary though ;-)

I don't understand, what is the significance of a 20kb binary? The only person using this would be someone who takes Zoom meetings on a company-issued computer and I can't imagine such machines are disk space-constrained.

I'm not aware of company issued computer with x11. Is it really a thing ?

Some companies let you run Linux on their company issued computer.

OBS lets you share a window or just the client area of an app.

With OBS, you can add an entire screen to your canvas and then add a filter to crop it down to a particular part of that screen. This nets you the same results as the small C++ tool being proposed here.

A lot more work involved, though.

It can do that, yes, but it's a bit more work. There are several GUI hoops you'll have to run through to get that to work, and if you have to adjust it each and every time, before a meeting, then it would become burdensome. But yes, it can be done.
