|
|
* e.g. NV12 (http://fourcc.org/yuv.php#NV12) is described as:
|
|
*
|
|
* YUV 4:2:0 image with a plane of 8 bit Y samples

* followed by an interleaved U/V plane containing

* 8 bit 2x2 subsampled colour difference samples.

* So it would consist of Y as offsets[0] and UV as
|
|
* offsets[1]. Note that offsets[0] will generally
|
|
* be 0 (but this is not required).
|
|
*
|
|
* To accommodate tiled, compressed, etc formats, a
|
|
* modifier can be specified. The default value of zero
|
|
* indicates "native" format as specified by the fourcc.
|
|
* Vendor specific modifier token. Note that even though
|
|
* it looks like we have a modifier per-plane, we in fact
|
|
* do not. The modifier for each plane must be identical.
|
|
* Thus all combinations of different data layouts for
|
|
* multi plane formats must be enumerated as separate
|
|
* modifiers.
