I've recently bought a Vero V and it's been playing anything I've thrown at it without any issues. That includes 4K, HDR10 and AVI videos.
This is the best media player I've had over the decades.
I've had a Nvidia Shield before. I was just not happy with the advertising platform it really was. Which is why I upgraded to the Vero V.
I am currently using scrypted (https://www.scrypted.app/) on debian. I found it scrytped easier to set-up and get into than frigate.
