I did not like the Rpi5 with Android TV as a jellyfin client. There is no support for Dolby Vision HDR content and playback of other 4k media was stuttering. With DV content I got the purple/green tinted picture. Sometimes the pi would only display a quarter of the picture.

I used Konstakangs AndroidTV image with a flirc USB Dongle for use with a tv remote. F-Droid store apk for all necessary apps.

If you have any recommendations how to fix stuttery 4k playback I would be interested. For now I just stick with the built in Android TV of my sony television.
