Just discovered that the 2nd camera, with the discoloured image, is also unable to cast to my Chromecast. The Chromecast just sits on the "Tapo" loading screen.

The 1st camera casts fine.

Looks like the 2nd camera is just knackered :(

A cold restart of the 2nd camera (unplug, wait 30s, replug) solved the discoloured image.

As for the issue with streaming to a Chromecast, that looks to be a bug with the Tapo casting implementation.

If you cast 1 camera to a Chromecast ("hey Google, Show Driveway on TV"), then immediately attempt to cast a 2nd camera to the Chromecast ("hey Google, Show Garden on TV"), then the Chromecast will stall on the "tapo" loading screen.

To get it to work correctly, you have to explicitly end the first cast ("hey Google, stop TV") before attempting to start the second cast.

I hope TP-Link will fix this rather obvious bug, as the workaround is pretty clunky.

While they're at it, the quality of the picture when casting to a Chromecast is *awful*.

There's no reason why the picture should be worse than what's shown in the Tapo App.

I get better picture quality screen mirroring my phone to the Chromecast while viewing the camera inside the Tapo app! Which is frankly ridiculous!
