Sorry,
I'm not going to support the Emby (Mediabrowser) plugin for VoxCommando anymore.
Emby has apparently made more changes to their authorization (and no doubt many other things) that are not backwards compatible even with their own SDKs which I used to create this plugin.
My guess is that the amount of work required to get this functional again would be huge and as far as I know there isn't really anyone who still uses Emby and VoxCommando, nor has anyone else requested any support to do this or even mentioned "Emby" and "VoxCommando" in the same post on the internet anywhere in the last year that I can find.
I will leave the plugin as part of the installation in case anyone is still using these two programs together. If any such person exists, then I guess they are using a very old version of Emby.
