STRUCT V4L2_DECODE_VBI_LINE(9)

📦 version 7.3.1, in nixpkgs unstable

✨ struct v4l2_decode_vbi_line(9) ✨

okay bestie, welcome to the Kernel API Manual 🎀 this one's a tiny little struct from the land of V4L2 subdevices, and tbh it's giving "small but crucial" 💅 it's literally the thing that helps you get your sliced VBI decode on. no cap.

🌸 NAME 🌸

struct v4l2_decode_vbi_line — literally the struct used to decode_vbi_line 🦋 that's it, that's the whole vibe check.

⭐ SYNOPSIS ⭐

struct v4l2_decode_vbi_line {
    u32 is_second_field;
    u8 *p;
    u32 line;
    u32 type;
 };

yes queen, four members, no more no less 👑

🫶 Members 🫶

okay so let's meet the cast, main character energy only:

  • is_second_field — set this to 0 for the first (odd) field, and set it to 1 for the second (even) field. pick your field, bestie 🎀
  • p — a pointer to the sliced VBI data coming from the decoder ✨ on exit, it points to the start of the payload. she moves, okay? don't be weird about it 💫
  • line — the line number of the sliced VBI data, and that's 1-23 🔥
  • type — the VBI service type (V4L2_SLICED_*), and it's 0 if no service was found 😭 literally nothing found, tragic
