camera_frame_nv12

A frame descriptor used for NV12 frame types

Synopsis:

#include <camera/camera_api.h>

#include <camera/camera_api.h>

typedef struct camera_frame_nv12_t {
    uint32_t height;
    uint32_t width;
    uint32_t stride;
    int64_t uv_offset;
    int64_t uv_stride;
} camera_frame_nv12_t;

Data:

uint32_t height: The height of the frame in pixels.
uint32_t width: The width of the frame in pixels.
uint32_t stride: The number of bytes between the first pixel of the first row in memory and the first pixel of the second row in memory of the luminance (Y) plane.; Stride is often called pitch. For more information, see the uv_stride member.
int64_t uv_offset: The number of bytes between the first pixel of the Y plane in memory and the first pixel of the UV plane in memory.; On a device where there is no gap between the Y and UV planes, the uv_offset would be height times stride bytes. This equivalence is not guaranteed across all devices, so it is important to observe the uv_offset value rather than attempting to compute the offset.
int64_t uv_stride: The number of bytes between the first pixel of the first row in memory and the first pixel of the second row in memory of the chrominance (UV) plane.; For more information, see the stride member.

Description:

Use this frame descriptor when CAMERA_FRAMETYPE_NV12 is reported as the camera_frametype_t.
