I just want to understand the frame structures that ffmpeg creates,
and that ffmpeg uses in processing and filtering. Are Y, Cb, Cr
separate buffers? That would be logical. Or are the Y, Cb, Cr values
combined and organized similarly to macroblocks? I've found some code
that supports that. Or are the Y, Cb, Cr values thrown together,
pixel-by-pixel. That would be logical, too.
As far as I understood it, that depends on the pixel format.
For example there are "packed" pixel formats rgb24, bgr24, argb, rgba,
abgr, bgra,rgb48be, rgb48le, bgr48be, bgr48le.
And there are "planar" pixel formats gbrp, bgrp16be, bgrp16le.
