STRUCT CONVERSION_MATRIX(9)

🦋 struct conversion_matrix(9) — Kernel API Manual 🦋

okay so bestie, welcome to the <pink>struct conversion_matrix</pink> page — manual name: Kernel API Manual. no cap, this struct is short but it's highkey giving main character energy in the kernel API. 💅

✨ NAME ✨

struct conversion_matrix — Matrix to use for a specific encoding and range. that's literally the whole name, and honestly? iconic. 🎀

🎀 SYNOPSIS 🎀

ngl bestie, the synopsis is short and sweet — vibe check passed:

struct conversion_matrix {
    s64 matrix[3][3];
    int y_offset;
 };

💅 Members 💅

• matrix — Conversion matrix from yuv to rgb. It's stored in a row-major manner and is used to compute rgb values from yuv values: [[r],[g],[b]] = matrix * [[y],[u],[v]] OR for yvu formats: [[r],[g],[b]] = matrix * [[y],[v],[u]]. The values of the matrix are signed fixed-point values with 32 bits fractional part. the way that math ate? obsessed. periodt. ✨
• y_offset — Offset to apply on the y value. that's the whole vibe, fr fr. 🫶
