@FelipeLema I hope you don't mind, I pushed some more fixes for the docs and viewcam.

Would you mind testing whether viewcam() works for you? On MacOS for me it loads and grabs images but nothing shows in the Makie window.

[FelipeLema]

it shows a blank screen to me too. Let me have a go at it

[FelipeLema]

It properly shows a x-flipped image from my webcam (mimics a mirror)

there are some other details (provided width & height is ignored), but I guess we can go with this one in the meantime

shoutouts to macOS' GateKeeper for quietly blocking me on this one for so long

[FelipeLema]

I dunno what's up with format linter, but this is ready to go

[IanButterworth]

Thanks I'll test locally and fix the formatter (this is the first PR after I added that, so it's good to fix it)
