please add a 'virtualcam' use-flag, that adds 'media-video/v4l2loopback' as dependency[1]. Or at least print a post installation message, that installing 'media-video/v4l2loopback' is required [1] to use the virtual cam feature in obs studio.

Thinking about this now, I thought I did already do something about it, but I guess I forgot. I did think of a USE-flag or even unconditional dependency on it, but being a kernel module it's a bit more complicated, so it will likely be a message of sorts. Thanks for the reminder!
I would strongly prefer a use-falg, since this way portage knows the dependencies between the packages. If you later uninstall obs-studio, portage would remove the no longer needed dependencies with an 'emerge -c'. If I manually install dependencies based on a post installation message, they are added to the world file and remain on my system even if obs-studio is uninstalled or the package is no longer required in a later version of obs-studio.

We have a policy against that though, https://projects.gentoo.org/qa/policy-guide/dependencies.html#pg0001 You can use portage sets where you can comment stuff. Like /etc/portage/sets/optfeature # obs-studio, virtual cam support media-video/v4l2loopback

Also add an 'optfeature' and an elog message regarding the virtual camera feature, and enable 'VST' by default since it's no longer a submodule, and doesn't seem to increase the size of things much at all. Lastly, adjust some of the existing elog message wording.

Considering the policy, and sets mentioned in comment 3, I'll be closing this off for now. There is at least that post-install message now, though I admit they probably go unnoticed for many users... In any case, thank you for the report!
