ENUM V4L2_AV1_WARP_MODEL(9)

🦋 enum v4l2_av1_warp_model(9) 🦋

okay so bestie, we're in the Kernel API Manual today and this page is literally the glow-up guide for AV1 warp models ✨

---

💅 NAME 💅

enum v4l2_av1_warp_model — the AV1 Warp Model, exactly as described in section 3 "Symbols and abbreviated terms" of the AV1 Specification. no cap, that's the whole vibe 🎀

---

🌸 SYNOPSIS 🌸

enum v4l2_av1_warp_model {
    V4L2_AV1_WARP_MODEL_IDENTITY ,
    V4L2_AV1_WARP_MODEL_TRANSLATION ,
    V4L2_AV1_WARP_MODEL_ROTZOOM ,
    V4L2_AV1_WARP_MODEL_AFFINE

};

---

✨ Constants ✨

these four are the whole main character lineup, let me introduce them 🫶

• V4L2_AV1_WARP_MODEL_IDENTITY — the warp model is just an identity transform. it does literally nothing and honestly? iconic for that 💀
• V4L2_AV1_WARP_MODEL_TRANSLATION — the warp model is a pure translation. just sliding, no rotation drama 🌈
• V4L2_AV1_WARP_MODEL_ROTZOOM — the warp model is a rotation + symmetric zoom + translation. three things at once, ate and left no crumbs 🔥
• V4L2_AV1_WARP_MODEL_AFFINE — the warp model is a general affine transform. the full glam, no restrictions 💜
