Perhaps you can use OBS instead of holding the space bar: https://xkcd.com/1172/ https://xkcd.com/1172/

Yeah, this script will also heat your home :) Especially, if you use the Zoom desktop client. Zoom on web (Firefox) seems to be easier on the CPU for some reason though.

  Any chance this could be integrated with OBS? To select filters, show previews, etc. Going forward, I wonder if OBS will offer pipewire or gstreamer streams (if those are a thing) for consumption by other apps?

    There is an OBS plugin that allows you to use gstreamer nodes as filters: https://github.com/fzwoch/obs-gstreamer https://github.com/fzwoch/obs-gstreamer

The last time I tried, v4l2loopback wasn't a part of my kernel, at which point I decided it wasn't worth it to tinker with as I didn't know the stability of the mod.

One thing to note about OBS, as much as I love it and use it all the time: if you're using it to record/stream just one source, you're likely wasting a lot of resources. I see many people using it to record/v4loopback their screen or camera, which OBS is not particularly efficient at. Not something you're likely to notice on a modern workstation, but on an older machine or laptop the overhead is definitely noticeable. Dedicated recording apps for cameras and screens will give you better performance and occasionally a marginally better image since there are fewer steps in the pipeline. For v4loopback, a short gstreamer pipeline (for those willing to use the CLI) will perform better and give you noticably lower latency - even if some basic cropping is required, like if you're using a capture card with a camera that you can't hide the UI on.

My 2015 MBP has a GT750M, but "thanks" to Apple OBS can't use hardware acceleration (https://obsproject.com/forum/threads/question-about-hardware-encoding-for-macbook-pros-local-recording.107093/ https://obsproject.com/forum/threads/question-about-hardware...). Situation on Linux is likely similar.
