VAR V4L2_FIELD_NAMES(9)

🎀 var v4l2_field_names(9) 🎀

ok so this is from the Kernel API Manual bestie, and it's genuinely one of those tiny-but-iconic ones. like, it's not doing the most, but it's carrying the whole debug-message situation on its back. 💅

---

✨ NAME ✨

v4l2_field_names — the helper array that maps V4L2_FIELD_* values to actual strings 🦋

---

🌸 SYNOPSIS 🌸

extern const char *v4l2_field_names[];

---

💖 Description 💖

okay so picture this: you're printing debug messages (which, lowkey, is most of kernel life 😭) and it's genuinely interesting to output the field order at the V4L2 buffers. so yeah, this array is the ✨moment✨ — it associates all possible values of field pix format from the V4L2 API into a string. one array, every possible value, all mapped, no cap. 🫶

like it's literally just a lookup table being its best self, and honestly? we love that for it. 👑

🫶 reminder bestie: that's <pink>all possible values</pink> of the field pix format — don't be out here assuming it covers stuff that isn't in the list, iykyk. 💀

ok that's the whole vibe 💜 this page lives in ./include/media, it's dated October 2026, it's part of that Kernel API Manual energy, and it's signed off with all the source/version realness at the bottom of the original. mwah, go read the debug output, you got this 🎀🌟
