Live TV - Multi Screen Feature

[mwongjay 83]

@hiimcourtyEmby's live tv management and features are underwhelming and have been for a long time. Fortunately, solutions do exist and add a lot of capability. I've used Xteve, IPTVBoss, Threadfin, and currently use Dispatcharr to manage a consolidated m3u and epg across 2 HDHomerun tuners and iptv streams with multiple epg sources including SchedulesDirect. Dispatcharr is hands-down the best and most feature rich. I copy the audio and video directly, but configure the ffmpeg flags for higher reliability/resiliency and Emby manages the specific device stream logic. 

As it pertains to your use case Dispatcharr has a multiview plugin that is hardware accelerated. One consideration is that a multiview 2x2 requires 4+ streams. If your provider limits you to 1 or 2 streams Dispatcharr can work around this by managing multiple IPTV accounts if needed.
