Is there a market for an open source streaming box, similar to Home Assistant? Jellyfin and other open servers ensure sovereignty over the media server end, but it seems like the end to end gap is client side.
Don't think so, there's always been the option to do this with a Raspberry Pi or a NUC-like box and Windows even supported being used for this for a while a long time ago, but the whole conversation these days seems centered around Jellyfin/Plex/Emby.
