DOLBY_VISION_10B_HDR_OEM

static val DOLBY_VISION_10B_HDR_OEM: Long

This is the camera mode for the default Dolby Vision capture mode for the specific device. This would be tuned by each specific device for consumer pleasing results that resonate with their particular audience. We expect that each specific device would have a different look for their default Dolby Vision capture.

Value: 64L

DOLBY_VISION_10B_HDR_OEM_PO

static val DOLBY_VISION_10B_HDR_OEM_PO: Long

This is the power optimized mode for 10-bit Dolby Vision HDR device specific capture Mode.

Value: 128L

DOLBY_VISION_10B_HDR_REF

static val DOLBY_VISION_10B_HDR_REF: Long

This is a camera mode for Dolby Vision capture optimized for a more scene accurate capture. This would typically differ from what a specific device might want to tune for a consumer optimized Dolby Vision general capture.

Value: 16L

DOLBY_VISION_10B_HDR_REF_PO

static val DOLBY_VISION_10B_HDR_REF_PO: Long

This is the power optimized mode for 10-bit Dolby Vision HDR Reference Mode.

Value: 32L

DOLBY_VISION_8B_HDR_OEM

static val DOLBY_VISION_8B_HDR_OEM: Long

This is the 8-bit version of device specific tuned and optimized Dolby Vision capture mode.

Value: 1024L

DOLBY_VISION_8B_HDR_OEM_PO

static val DOLBY_VISION_8B_HDR_OEM_PO: Long

This is the power optimized mode for 8-bit Dolby Vision HDR device specific capture Mode.

Value: 2048L

DOLBY_VISION_8B_HDR_REF

static val DOLBY_VISION_8B_HDR_REF: Long

This is the 8-bit version of the Dolby Vision reference capture mode optimized for scene accuracy.

Value: 256L

DOLBY_VISION_8B_HDR_REF_PO

static val DOLBY_VISION_8B_HDR_REF_PO: Long

This is the power optimized mode for 8-bit Dolby Vision HDR Reference Mode.

Value: 512L

HDR10

static val HDR10: Long

10-bit pixel samples encoded using the SMPTE ST 2084 transfer function.

This profile utilizes internal static metadata to increase the quality of the capture.

Value: 4L

HDR10_PLUS

static val HDR10_PLUS: Long

10-bit pixel samples encoded using the SMPTE ST 2084 transfer function.

In contrast to HDR10, this profile uses internal per-frame metadata to further enhance the quality of the capture.

Value: 8L

HLG10

static val HLG10: Long

10-bit pixel samples encoded using the Hybrid log-gamma transfer function

All 10-bit output capable devices are required to support this profile.

Value: 2L

PUBLIC_MAX

static val PUBLIC_MAX: Long

Value: 4096L

STANDARD

static val STANDARD: Long

This the default 8-bit standard profile that will be used in case where camera clients do not explicitly configure a supported dynamic range profile by calling OutputConfiguration#setDynamicRangeProfile.

Value: 1L

DynamicRangeProfiles

DynamicRangeProfiles(elements: LongArray)

Create a new immutable DynamicRangeProfiles instance.

This constructor takes over the array; do not write to the array afterwards.

Do note that the constructor is available for testing purposes only! Camera clients must always retrieve the value of android.hardware.camera2.CameraCharacteristics#REQUEST_AVAILABLE_DYNAMIC_RANGE_PROFILES. for a given camera id in order to retrieve the device capabilities.

getProfileCaptureRequestConstraints

fun getProfileCaptureRequestConstraints(profile: Long): MutableSet<Long!>

Return a list of supported dynamic range profiles that can be referenced in a single capture request along with a given profile.

For example if assume that a particular 10-bit output capable device returns (STANDARD, HLG10, HDR10) as result from calling getSupportedProfiles() and getProfileCaptureRequestConstraints returns (STANDARD, HLG10) when given an argument of STANDARD. This means that the corresponding camera device will only accept and process capture requests that reference outputs configured using HDR10 dynamic profile or alternatively some combination of STANDARD and HLG10. However trying to queue capture requests to outputs that reference both HDR10 and STANDARD/HLG10 will result in IllegalArgumentException.

The list will be empty in case there are no constraints for the given profile.

getSupportedProfiles

fun getSupportedProfiles(): MutableSet<Long!>

Return a set of supported dynamic range profiles.

isExtraLatencyPresent

fun isExtraLatencyPresent(profile: Long): Boolean

Check whether a given dynamic range profile is suitable for latency sensitive use cases.

Due to internal lookahead logic, camera outputs configured with some dynamic range profiles may experience additional latency greater than 3 buffers. Using camera outputs with such profiles for latency sensitive use cases such as camera preview is not recommended. Profiles that have such extra streaming delay are typically utilized for scenarios such as offscreen video recording.
