Advanced capture properties for Windows Phone 8
[ This article is for Windows Phone 8 developers. If you’re developing for Windows 10, see the latest documentation. ]
This topic describes the camera, photo, audio, and video properties that you can use for advanced capture scenarios in Windows Phone apps. Because different phones may support different sets of properties, they are not explicitly defined as object properties. Instead, the PhotoCaptureDevice and AudioVideoCaptureDevice objects provide the SetProperty and GetProperty methods to assign properties to the capture device. For more info about setting properties, see Advanced photo capture for Windows Phone 8.

To determine which properties are supported on each phone, use the GetSupportedPropertyValues and GetSupportedPropertyRange methods. Each property will support one of these methods, but not both. A valid call to the GetProperty method will always return a value of type Object. Use the tables in this topic to determine the object types that correspond to each property, and whether GetSupportedPropertyValues or GetSupportedPropertyRange can be used with each property. |
This topic contains the following sections.

Camera properties
Use the KnownCameraGeneralProperties class to assign general camera properties. Properties in this class can be assigned to both types of capture device objects, PhotoCaptureDevice and AudioVideoCaptureDevice. The KnownCameraGeneralProperties class returns GUID values that you can use with the capture device GetProperty and SetProperty methods. You can also assign these properties to the DesiredProperties property of a frame.
For each property, the following table lists the type of object that is returned by GetProperty, and whether GetSupportedPropertyValues (the “get values” column) or GetSupportedPropertyRange (the “get range” column) can be used.

Photo properties
Photo properties are only applicable to the PhotoCaptureDevice object. The KnownCameraPhotoProperties class returns GUID values that you can use with the GetProperty and SetProperty methods. You can also assign these properties to the DesiredProperties property of a frame.
For each property, the following table lists the type of object that is returned by GetProperty, and whether GetSupportedPropertyValues (the “get values” column) or GetSupportedPropertyRange (the “get range” column) can be used.

Audio and video properties
Audio and video properties are only applicable to the AudioVideoCaptureDevice object. The KnownCameraAudioVideoProperties class returns GUID values that you can use with the GetProperty and SetProperty methods.
For each property, the following table lists the type of object that is returned by GetProperty, and whether GetSupportedPropertyValues (the “get values” column) or GetSupportedPropertyRange (the “get range” column) can be used.
