I need video streaming for home. My needs are:

* Windows server (existing W10 machine with JBOD)
* Apple clients (iPhone, iPad, MacBook, AppleTV)
* Multiple playback streams simultaneously
* WAF high (will also be used by kids)
* Possible to save video onto client devices for offline watching while away from home
* Ability to control any stream from any device (for keeping checks on kids)
* Support of as high resolution as possibly relevant (can one even rip 4K BD discs???)
* Support of crummy video files too
* Doesn't have to be entirely free, but please not Kaleidescape prices.

I understood Plex to be the front runner but I think in the past few years more have appeared. (My Dad uses Emby and recommends it.)

Recommendations?
