validate_av1_sequence(9)

💅 validate_av1_sequence(9) — like, the Kernel API Manual page, bestie 🎀

okay so welcome to the Kernel API Manual entry for validate_av1_sequence(9) — yes that's the whole vibe, we're in the kernel docs section and this one is short but iconic ✨

---

🌸 NAME 🌸

validate_av1_sequence — it validates the fields in an AV1 sequence header, no cap 🦋

---

✨ SYNOPSIS ✨

int validate_av1_sequence (struct v4l2_ctrl_av1_sequence *s );

like, that's the whole signature, she's neat 💅

---

🫶 ARGUMENTS 🫶

• s — the control struct that came from userspace 👑 that's the thing getting vibe-checked.

---

💖 DESCRIPTION 💖

okay so real talk: this function implements the AV1 spec §5.5.2 color_config checks — the ones that are actually possible with the current v4l2_ctrl_av1_sequence definition 💀 like it can only check what it's been given, bestie.

TODO: extend the validation once additional fields such as color_primaries, transfer_characteristics, matrix_coefficients, and chroma_sample_position get added to the uAPI 🔥 that's the future glow-up, fr fr.

Returns 0 if valid, -EINVAL otherwise 🧚 so yeah, 0 = slay, -EINVAL = not it.
