DynamicRangeProfiles

public final class DynamicRangeProfiles
extends Object

java.lang.Object
   ↳ android.hardware.camera2.params.DynamicRangeProfiles


Immutable class with information about supported 10-bit dynamic range profiles.

An instance of this class can be queried by retrieving the value of CameraCharacteristics.REQUEST_AVAILABLE_DYNAMIC_RANGE_PROFILES.

All camera devices supporting the CameraMetadata.REQUEST_AVAILABLE_CAPABILITIES_DYNAMIC_RANGE_TEN_BIT capability must advertise the supported 10-bit dynamic range profiles in getSupportedProfiles()

Some devices may not be able to support 8-bit and/or 10-bit output with different dynamic range profiles within the same capture request. Such device specific constraints can be queried by calling getProfileCaptureRequestConstraints(long). Do note that unsupported combinations will result in IllegalArgumentException when trying to submit a capture request. Capture requests that only reference outputs configured using the same dynamic range profile value will never fail due to such constraints.

Public constructors

DynamicRangeProfiles

Added in API level 33
public DynamicRangeProfiles (long[] elements)

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 CameraCharacteristics.REQUEST_AVAILABLE_DYNAMIC_RANGE_PROFILES. for a given camera id in order to retrieve the device capabilities.

Parameters
elements long: An array of elements describing the map. It contains three elements per entry. The first element describes the supported dynamic range profile value. The second element contains a bitmap of concurrently supported dynamic range profiles within the same capture request. The third element contains a hint about extra latency associated with the corresponding dynamic range. Bitmap values of 0 indicate that there are no constraints. This value cannot be null.

Throws
IllegalArgumentException if the elements array length is invalid, not divisible by 3 or contains invalid element values
NullPointerException if elements is null

Public methods

getProfileCaptureRequestConstraints

Added in API level 33
public Set<Long> getProfileCaptureRequestConstraints (long profile)

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(long) 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.

Parameters
profile long: Value is STANDARD, HLG10, HDR10, HDR10_PLUS, DOLBY_VISION_10B_HDR_REF, DOLBY_VISION_10B_HDR_REF_PO, DOLBY_VISION_10B_HDR_OEM, DOLBY_VISION_10B_HDR_OEM_PO, DOLBY_VISION_8B_HDR_REF, DOLBY_VISION_8B_HDR_REF_PO, DOLBY_VISION_8B_HDR_OEM, or DOLBY_VISION_8B_HDR_OEM_PO

Returns
Set<Long> non-modifiable set of dynamic range profiles This value cannot be null.

Throws
IllegalArgumentException If the profile argument is not within the list returned by getSupportedProfiles()

getSupportedProfiles

Added in API level 33
public Set<Long> getSupportedProfiles ()

Return a set of supported dynamic range profiles.

Returns
Set<Long> non-modifiable set of dynamic range profiles This value cannot be null.

isExtraLatencyPresent

Added in API level 33
public boolean isExtraLatencyPresent (long profile)

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.

Parameters
profile long: Value is STANDARD, HLG10, HDR10, HDR10_PLUS, DOLBY_VISION_10B_HDR_REF, DOLBY_VISION_10B_HDR_REF_PO, DOLBY_VISION_10B_HDR_OEM, DOLBY_VISION_10B_HDR_OEM_PO, DOLBY_VISION_8B_HDR_REF, DOLBY_VISION_8B_HDR_REF_PO, DOLBY_VISION_8B_HDR_OEM, or DOLBY_VISION_8B_HDR_OEM_PO

Returns
boolean true if the given profile is not suitable for latency sensitive use cases, false otherwise

Throws
IllegalArgumentException If the profile argument is not within the list returned by getSupportedProfiles()
