12Intro to YUV image formats:
13YUV_420_888 - is a generic format that can be represented as I420, YV12, NV21, and NV12.
14420 means that for each 4 luminosity pixels we have 2 chroma pixels: U and V.
15
16* I420 format represents an image as Y plane followed by U then followed by V plane
17 without chroma channels interleaving.
18 For example:
19 Y Y Y Y
20 Y Y Y Y
21 U U V V
22
23* NV21 format represents an image as Y plane followed by V and U interleaved. First V then U.
24 For example:
25 Y Y Y Y
26 Y Y Y Y
27 V U V U
28
29* YV12 and NV12 are the same as previous formats but with swapped order of V and U. (U then V)
30
31Visualization of these 4 formats:
32https://user-images.githubusercontent.com/9286092/89119601-4f6f8100-d4b8-11ea-9a51-2765f7e513c2.jpg
33
34It's guaranteed that image.getPlanes() always returns planes in order Y U V for YUV_420_888.
35https://developer.android.com/reference/android/graphics/ImageFormat#YUV_420_888
36
37Because I420 and NV21 are more widely supported (RenderScript, OpenCV, MNN)
38the conversion is done into these formats.
