I have downloaded a couple of files to my surface pro 3 so that I can watch them when I'm away from home. I am unable to stream them from home via my phones hotspot due to plan limitations. In my holiday house I have a chromecast set up on the TV and it connects to my phone hotspot as does my surface pro 3.
I would like to be able to playback the downloaded files on the Chromecast using Emby UWP or Emby Theater desktop, but they do not give me the option of using the chromecast as a playback device.
For comparison, VLC has no problem with this scenario.
