Casting a browser or whole screen can be done with Chrome/Chromium on Linux. Whole screen doesn't work with wayland. Redirecting system audio doesn't work either.

If you redirect a tab which is mostly a single video file, it is smart enough to do the video decoding directly on the chromecast, so you get much better quality/framerate.

I was interested to find out that the youtube app on an amazon fire stick is supported as a chromecast target now.

It doesn't support casting a browser tab or a desktop though (the latter isn't surprising as I'm under wayland which the parent says doesn't work, but I'd guess a browser tab should work? would be interested in other peoples experiences of this).
