Back to this one, my apologies for dropping it temporarily. Given that tvOS is like iOS in that I would have to dismantle and repack the official Kodi package, I am afraid that it's probably not in the cards, at least not anytime in the near future. I do still do the "repack" thing with UWP, and used to do it with Android until Leia came around, but it's a bad way to go. As Fuzzard indicated, it is pretty difficult to set up and get right, but difficult isn't really the problem for me. (If it ain't hard, why do it, right?)
Doing things this way what you end up with is a Kodi-like package. It will still say Kodi, and it will technically be the same exact software, but the user has no way to guarantee that. Any mistake on my part would end up being reported to Kodi, but it's not their package to support -- technically this would be a fork. I'm not sure how tvOS will be distributed, but if it comes from the App Store like Android and UWP does, updates get all messed up too. Let's say Kodi 18.7 comes out, you actually need to wait for me to get it and repackage it before you can install it. There can't be any automatic updates since it's not the same package.
I am also aware that Apple has become more strict about application and package signing, which is a good thing, but does add a bit of complication for me. To give you something installable without hacking it up or making you trust a root certificate (this step is needed on UWP today), I would need to apply for and maintain a proper Apple developer ID. It's speculation on my part here, but I imagine that Apple's rules would prevent me from taking someone else's code and pretending it's mine. I don't want to tick off Apple even moreso than I don't want to tick off Kodi
I know this seems like a lot of justification instead of just saying "no, sorry", but I wanted to make sure you knew why for now I have to say "no, sorry".
The BEST way to handle this is for me to get back to trying to port some of the features to the official pvr.hdhomerun addon for y'all. We tried one (Recordings), but it didn't work out quite as hoped. Will try that one again soon since I did learn the bug I thought I caused wasn't related. There is a cool new inputstream in Matrix that allows for most, if not all, of the tricks I play with HDHomeRun RECORD to work now!
