STRUCT VDEC_AV1_SLICE_GM(9)

💅 struct vdec_av1_slice_gm(9) — like, the AV1 Global Motion parameters era 🎀

okay bestie, sit down, because this is the struct vdec_av1_slice_gm page from the Kernel API Manual and it's literally the blueprint for AV1 Global Motion parameters. yes, that's the whole name. we're starting strong. ✨

---

🌸 NAME 🌸

struct vdec_av1_slice_gm — AV1 Global Motion parameters. that's it, that's the vibe. she's a struct, she holds global motion stuff, and she's iconic for it. 💖

---

🦋 SYNOPSIS 🦋

look at her. look at the whole layout. no notes, she ate:

struct vdec_av1_slice_gm {
    int wmtype;
    int wmmat[8];
    short alpha;
    short beta;
    short gamma;
    short delta;
    char invalid;
 };

(slight lil' formatting quirk at the end there with the }; — that's exactly how she's written in the manual, so we're keeping her exactly as she is, no cap 🫶)

---

👑 Members 👑

okay so here's the cast of characters, one by one, main character energy each:

• wmtype — the type of global motion transform used. this is the big one. it tells you which transform vibe we're on. 🔥
• wmmat — gm_params. yeah, that's the description. that's literally it. short and mysterious, she's giving cryptic. 🙈
• alpha — alpha info. that's the info. about alpha. 💅
• beta — beta info. same energy, different letter. ⭐
• gamma — gamma info. we're just going down the Greek alphabet at this point and honestly? slay. 🌈
• delta — delta info. fourth one. consistent queen. 🦋
• invalid — is invalid or not. yes, that's the whole description, and yes, it's kind of a mood. she tells you if the thing is invalid or not and refuses to elaborate. 💀

bestie note: those member descriptions are exactly as terse as the original manual gives them — so don't come for me, I'm just the messenger 🎀
