* difference that it fills a struct ycbcr with a description of the buffer

*
* This will only work on buffers with HAL_PIXEL_FORMAT_YCbCr_*_888, and
* will return -EINVAL on any other buffer formats.
* If the buffer format is not compatible with a flexible YUV format (e.g.
* the buffer layout cannot be represented with the ycbcr struct), it
* will return -EINVAL.
*
* This method must work on buffers with HAL_PIXEL_FORMAT_YCbCr_*_888
* if supported by the device, as well as with any other format that is
* requested by the multimedia codecs when they are configured with a
* flexible-YUV-compatible color-format with android native buffers.
*
* Note that this method may also be called on buffers of other formats,
* including non-YUV formats.

* Added in GRALLOC_MODULE_API_VERSION_0_2.
