Maybe the switch for me would require staging on a burner pixel that supported. I have a lot of shopping apps, that I may not need, but need some time on the testing phone to make sure everything works before taking the deep dive.
This is also how I made the switch off windows. Stagged it on a space older laptop to see what's what.
I'll get there...
I found using Kodi helped resolve video codec support in my case. It was for AV1 nlon the Chromecast 4k, which doesn't support AV1, it seems to mostly work for smaller AV1 encodes. I guess it is using software decoding.
