Attributes

RegisterAttribute

Remarks

The version of the session configuration query CameraDevice.CameraDeviceSetup.isSessionConfigurationSupported(SessionConfiguration) and CameraDevice.CameraDeviceSetup.getSessionCharacteristics(SessionConfiguration) APIs.

The possible values in this key correspond to the values defined in android.os.Build.VERSION_CODES. Each version defines a set of feature combinations the camera device must reliably report whether they are supported via CameraDevice.CameraDeviceSetup.isSessionConfigurationSupported(SessionConfiguration). It also defines the set of session specific keys in CameraCharacteristics when returned from CameraDevice.CameraDeviceSetup.getSessionCharacteristics(SessionConfiguration). The version is always less or equal to android.os.Build.VERSION.SDK_INT.

If set to UPSIDE_DOWN_CAKE, this camera device doesn't support the CameraDevice.CameraDeviceSetup API. Trying to create a CameraDeviceSetup instance throws an UnsupportedOperationException.

From VANILLA_ICE_CREAM onwards, the camera compliance tests verify a set of commonly used SessionConfigurations to ensure that the outputs of CameraDevice.CameraDeviceSetup.isSessionConfigurationSupported(SessionConfiguration) and CameraDevice.CameraDeviceSetup.getSessionCharacteristics(SessionConfiguration) are accurate. The application is encouraged to use these SessionConfigurations when turning on multiple features at the same time.

When set to VANILLA_ICE_CREAM, the combinations of the following configurations are verified by the compliance tests: A set of commonly used stream combinations:; MAXIMUM_4_3 refers to the camera device's maximum output resolution with 4:3 aspect ratio for that format from StreamConfigurationMap#getOutputSizes; MAXIMUM_16_9 is the maximum output resolution with 16:9 aspect ratio; S1440P refers to 2560x1440 (16:9); S1080P refers to 1920x1080 (16:9); S720P refers to 1280x720 (16:9); UHD refers to 3840x2160 (16:9); XVGA refers to 1024x768 (4:3); S1080P_43 refers to 1440x1080 (4:3); VIDEO_STABILIZATION_MODE: {OFF, PREVIEW}; AE_TARGET_FPS_RANGE: { {*, 30}, {*, 60} }; DYNAMIC_RANGE_PROFILE: {STANDARD, HLG10}

When set to BAKLAVA, the additional stream combinations below are verified by the compliance tests: VIDEO_STABILIZATION_MODE: {OFF, ON} for the newly added stream combinations given the presence of dedicated video stream

All of the above configurations can be set up with a SessionConfiguration. The list of OutputConfiguration contains the stream configurations and DYNAMIC_RANGE_PROFILE, and the AE_TARGET_FPS_RANGE and VIDEO_STABILIZATION_MODE are set as session parameters.

This key is available on all devices.
