STRUCT VDEC_AV1_SLICE_SCALE_FACTORS(9)

🎀 NAME 🎀

okay so bestie, welcome to the Kernel API Manual — this page is all about struct vdec_av1_slice_scale_factors, which is literally the scale info for each ref frame. no cap, that's the whole assignment. 💅✨

✨ SYNOPSIS ✨

here she is, the struct in all her glory — do not touch the syntax, she's perfect:

       struct vdec_av1_slice_scale_factors {
           u8 is_scaled;
           int x_scale;
           int y_scale;
           int x_step;
           int y_step;
        };

💅 Members 💅

bestie, these are the fields one by one, no skipping, we respect the whole struct 🫶

• is_scaled — tells you whether the frame is scaled or not. like a little yes/no vibe check for scaling 🌸
• x_scale — the frame width scale coefficient, aka the horizontal scaling number ✨
• y_scale — the frame height scale coefficient, the vertical twin of x_scale 🦋
• x_step — the width step for x_scale, so it's the step that pairs with the width scaling 🎀
• y_step — the height step for y_scale, matching step for the height scaling 💜
