If you want to access an `AVFrame` structure directly, you should look at `data[0]` (for Y), `data[1]` (for U), and `data[2]` (for V). For Y plane you should read `height` lines, `linesize[0]` bytes per line. For U and V planes, there will be `height/2` lines, and linesize[1] and linesize[2] will define bytes per line for each plane. `linesize` is expected to be the same for U and for V.
