So what it really is, is the size of one audio channel's buffer ("planes", which
is also a hideous abuse of the word.).

FWIW I think audio "planes" and "linesize" are abominations which have sprung
up from reusing AVFrame for audio, using video-specific fields. I have no idea
how anyone outside of FFmpeg/Libav could understand this...

Is the above at least documented somewhere public?
