* P010 is a 4:2:0 YCbCr semiplanar format comprised of a WxH Y plane
* followed immediately by a Wx(H/2) CbCr plane. Each sample is
* represented by a 16-bit little-endian value, with the lower 6 bits set
* to zero.
*
* This format assumes
* - an even height
* - a vertical stride equal to the height
*
* stride_in_bytes = stride * 2
* y_size = stride_in_bytes * height
* cbcr_size = stride_in_bytes * (height / 2)
* cb_offset = y_size
* cr_offset = cb_offset + 2
*
* This format must be accepted by the allocator when used with the
* following usage flags:
*
* - BufferUsage::VIDEO_*
* - BufferUsage::CPU_*
* - BufferUsage::GPU_TEXTURE
*
* The component values are unsigned normalized to the range [0, 1], whose
* interpretation is defined by the dataspace.
*
* This format is appropriate for 10bit video content.
*
* Buffers with this format must be locked with IMapper::lockYCbCr
* or with IMapper::lock.
