Remarks

An instance of MediaCaptureVideoProfileMediaDescription defines a group of capture settings that are supported by a video profile. For example, a single video profile may support recording 720p video at 30 fps with HDR video support and also support recording 1080p video at 30 fps without HDR video support. In this case, each of these would be represented by a MediaCaptureVideoProfileMediaDescription object in the SupportedRecordMediaDescription list of the video profile. Each profile contains separate lists of media descriptions for photo capture, preview, and video recording. For more information on video profiles, see MediaCaptureVideoProfile.

You configure the capture device to use a particular MediaCaptureVideoProfileMediaDescription by using the MediaCaptureInitializationSettings object. It is important that the video profile media description values you use when configuring the device are compatible with the other initialization settings. For more information on how to correctly use media profile descriptions in the MediaCaptureInitializationSettings, see MediaCaptureInitializationSettings.PhotoMediaDescription, MediaCaptureInitializationSettings.PreviewMediaDescription, and MediaCaptureInitializationSettings.RecordMediaDescription.

For how-to guidance for working with video profiles, see Discover and select camera capabilities with camera profiles.
