union { ... } data

Pointer to the data held in this metadata entry.

The type field above defines which union member pointer is valid. The count field above defines the length of the data in number of elements.

◆ f

const float* f

◆ i32

const int32_t* i32

◆ i64

const int64_t* i64

◆ r

◆ tag

uint32_t tag

The tag identifying the entry.

It is one of the values defined in NdkCameraMetadataTags.h, and defines how the entry should be interpreted and which parts of the API provide it. See NdkCameraMetadataTags.h for more details.

◆ type

uint8_t type

The data type of this metadata entry.

Must be one of ACAMERA_TYPE_* enum values defined above. A particular tag always has the same type.

◆ u8

const uint8_t* u8
