Do you have a good sense of what boards are worth looking at for media center use cases? In the last few years it's become the norm to need to be able to drive a 4k display with HDR metadata, and decode 4k HEVC with HDR in hardware (and ideally pass through Dolby Vision as well). The dream is to be able to do that with a relatively inexpensive board with just the mainline kernel. I've had bad luck with the Pi 4 with respect to video decoding. 4k HEVC decoding is an advertised feature of the Pi 4, but it chokes on anything with moderate bitrates in my experience. I'd like my next board to support HDR and HEVC so reliably that I never have to think about it, and I'm not sure if that's going to be the Pi 5 or not.
