This is how to get your values from the initparams in your app.cs file app startup event... Put the values in as a resource...
<param name="initParams" value="MYKEY=MYVALUE"/>
private void Application_Startup(object sender, StartupEventArgs e)
if (e.InitParams != null)
foreach (var item in e.InitParams)
this.RootVisual = new MainPage();
To Get at em in your player
if (!ReferenceEquals(App.Current.Resources["MYKEY"], null))
MYKEYVAR = App.Current.Resources["MYKEY"].ToString();
The BitrateMonitor CLASS has a property
Gets or sets the highest bitrate for playback.
