From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

USB webcam lagging only in Zoom? (lemmy.ca)

Sorry if this community isn't the right place to ask — I got a USB webcam that works great in Teams, but lags tremendously (3-4 seconds) in Zoom. I doubt the Zoom app is introducing that lag on its own, but how would I troubleshoot this?

This is on EndeavourOS (basically Arch)

I also wondered for quite some time why my Logitech C920 webcam seemed to be using much lower framerates (which could be perceived as "laggy") in Linux as compared to Windows. It turns out it was transmitting uncompressed YUV frames by default, and for that, the bandwidth of my USB port just wasn't enough. (Maybe in USB C it would be enough, but this webcam isn't USB C.)

It worked like a charm after I manually set the format to H.264 in OBS. ("Like a charm" meaning it was transmitting 1920x1080 at 30 fps.) Unfortunately, I don't know how to do that in an application-agnostic way, but maybe someone else here can enlighten us. Worst case, install https://github.com/umlaeute/v4l2loopback and pipe your webcam stream through OBS...

I think it's possible that this is the same problem that you have run into.
