This sample demonstrates the Play To API.

The Play To sample demonstrates how you can expand your media application and add the capability to stream video, audio, and images to other devices on your local network. For example, a user that is watching a video in your application can stream that video to their TV for everyone in the room to view. This sample demonstrates how to stream a media file and how to stream pictures as a slide show.

You can use Windows Media Player as a Play To target device. To do this, open Windows Media Player on a separate computer, and then expand the Stream menu and select "Allow remote control of my Player". You can then add Windows Media Player on the other computer as a Digital media renderer in the Devices and Printers control panel.

If you use the code from the C# version of this sample in your own app, please be aware of the following known issues:

Known issue Workaround
Callback handlers for the MediaElement element cannot reference the UI thread directly. If you attempt to reference a MediaElement element directly, you will encounter an RPC_E_WRONG_THREAD exception for invoking a call to the element on the wrong thread. Implement a dispatcher to handle RPC calls for the MediaElement callback handler as seen in this example from ScenarioOutput1.xaml.cs.
C# 
void receiver_VolumeChangeRequested(Windows.Media.PlayTo.PlayToReceiver sender,
                                    VolumeChangeRequestedEventArgs args)
{
    PlayToReceiver.Dispatcher.Helper.BeginInvoke(() =>
    {
        if (dmrVideo != null)
        {
            dmrVideo.Volume = args.Volume;
        }
    });
}
