[hollanderbart]

This will resolve the #14 bug and will improve the user experience. It will now only show a previous of the channel when it is in focus.

[hollanderbart]

also resolved #12

@hollanderbart thanks!

I gave this a try, but ran into:

I did run pod install. I'm on Xcode 9.3 and run tvOS 11.3.

I fixed it by setting this setting:

[hollanderbart]

Ok, I will fix that. Thanks for mentioning FokkeZB. Much appreciated!!
But the big question is, does it work better now?

[FokkeZB]

It does! I did notice some lag when going through the menu. Perhaps there should be some delay before loading the stream to prevent that?

[hollanderbart]

Needs a lot more testing though. I’m looking for users who are willing to test this before I want to release a next version.

[hollanderbart]

Good point. I was already thinking about this as a possible solution. But it already avoids the loading spinner screens by only presenting the preview when the video buffer is full. Maybe I can check/verify if the video buffering is done on the background.
