Raspberry Pi 3, jerky playback, low FPS, sluggish interface menu

[scottbouch]

Recent update of Emby Theatre for Raspberry Pi results in playback being slow and jerky, probably 3 or 4 FPS estimate.

Also worth noting the interface is very sluggish to respond too to commands when browsing the menus, this issue appears to be a general device interface issue rather than playback specific, as everything is slow and clunky.

This Raspberry Pi 3 previously worked fine on Kodi (Libreelec & OSMC), and RasPlex. It is connected to the network by Ethernet for this Emby Theatre test.

Thanks, Scott
