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.

uint8_t * framebuf

A pointer to the frame data.

uint64_t framemetasize

The size of the metadata frame.

void * framemeta

A pointer to the metadata frame.

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

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.

Library:

libcamapi

Description:

This task can include handling buffers in callbacks and all functions that utilize buffers.
