Serviio

First of all: you did a great job ! Serviio is really good & very stylish too

I'd like to integrate serviio into my home-automation, for this reason I'd have to controll at least
- volume
- source (selection of different online-streams) and Playlists

via a simple http-command, just like
http:\\IP_serviio\volume=50
or
http:\\IP_serviio\source=onlinestream?playstream=2

I tried a litte bit, I can switch to the Onlinestreams when I use
http:\\IP_serviio:23424/mediabrowser/#/browse/A_OF?title=Online&b=Home&b=Musik&bid=0&bid=A
so I guess my feature-wishes could be possible.

If I had to use a API - i read the documentation but I did not find the solution - maybe you could just turn me in the right direction
The only problem use a API is the login/authorisation: if it is as complicated as written in den CDS-API I could not implement it on my homecontrol-server
For me it would be enough to use a specific port because my router to the WWW will not open this port to the WWW - that is secure enough
(or a simple test-"password")

CDS API is the way to browse / play.

For volume, that is not supported and is a feature of clients rather than the server.

I just thought because there is a volume control in the "play"-screen - there is no way to claim control to this shifter?

You'd have to invoke some javascript if you want to control the MediaBrowser web app. No idea how

You can also take the approach of wrapping the entire contents of a script in a function and having that outer function use strict mode.
