✨ NAME ✨

daala_plane_info — Subsampling factors for a plane as a power of 2. that's it, that's the whole vibe. 🎀

🦋 SYNOPSIS 🦋

#include <codec.h>

💅 Data Fields 💅

• unsigned char xdec — the x-direction subsampling factor, fr fr
• unsigned char ydec — and the y-direction one, obviously ✨

🌈 Detailed Description 🌈

so the whole thing here is Subsampling factors for a plane as a power of 2. that's the entire personality. it's giving "small struct, big responsibility" 👑

like, say you're doing 4:2:0. in that case the Y plane would have {0, 0} — no subsampling, living its best life — while Cb and Cr each get {1, 1}, because they're subsampled and that's just how it is 💜

so yeah: powers of 2, per-plane, x and y, done. lowkey elegant, highkey useful 🫶
