Remarks

Video profiles provide a simple way to configure the video capture device with a group of settings that are guaranteed to work with a particular capture device and are optimized for your desired capture scenario. There is a set of known video profiles that the system provides for common scenarios, such as capturing high-quality photos or video, capturing a photo sequence, or video conferencing. To get a list of the known video profiles for a given video device, use MediaCapture.FindKnownVideoProfiles. Some hardware vendors may expose other video profiles that you can get by calling MediaCapture.FindAllVideoProfiles.

A video profile exposes three lists of MediaCaptureVideoProfileMediaDescription objects, SupportedPhotoMediaDescription, SupportedPreviewMediaDescription, and SupportedRecordMediaDescription. Each item in these lists is a group of settings that are supported for the corresponding operation. 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.

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

Before using video profiles, you should check the value returned by MediaCapture.IsVideoProfileSupported to make sure that video profiles are supported by the capture device.

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