Member Data Documentation

uint64_t timestamp { 0 }

Frame timestamp at end of exposure in nanoseconds.

Note: The time base varies between the platforms. On Android CLOCK_MONOTONIC is used, the current timestamp can be obtained with clock_gettime().

uint32_t stride { 0 }

Stride value indicating how many bytes are used per row.

Note: If the frame is tightly packed this should equal to width * bytes per pixel. For NV12 and NV21 images, this should be the stride of the Y plane in bytes and the stride of the UV plane must be identical. For YUV420p and YV12 images, this should be the stride of the Y plane in bytes. The stride of the U and V planes must be exactly half of that.
