camera_buffer

The camera buffer structure is used to convey image data between the API and an application and to adequately describe the format of the image data.

Synopsis:

#include <camera/camera_api.h>

typedef struct  {
    camera_frametype_t frametype ;
    uint64_t framesize ;
    uint8_t * framebuf ;
    uint64_t framemetasize ;
    void * framemeta ;
    int64_t frametimestamp ;
    int32_t frameorientation ;
    uint32_t reserved [4];
    camera_framedesc_t framedesc ;
}camera_buffer_t;

Since:

BlackBerry 10.0.0

Data:

camera_frametype_t frametype: The type of frame descriptor that is used to distinguish between members of the camera_framedesc_t union.

uint64_t framesize: The size of the camera_buffer_t structure.; Note: This does not describe the size of the image data pointed to by framebuf. The actual image size must be computed using format-specific fields in the appropriate camera_framedesc_t member.

uint8_t * framebuf: A pointer to the frame data.

uint64_t framemetasize: The size of the associated metadata.

void * framemeta: A pointer to the associated metadata.

int64_t frametimestamp: The timestamp when the buffer was filled.; The timestamp is referenced to the system monotonic clock (CLOCK_MONOTONIC).

int32_t frameorientation: The rotation delta from the default device orientation.; The rotation is measured in degrees, clockwise.

uint32_t reserved[4]: For internal use.; Do not use.

camera_framedesc_t framedesc: The union which describes the geometry of the image data being reported by the framebuf field in this structure.
