💅 nal_hevc_read_filler(9)

okay so bestie, welcome to the Kernel API Manual ✨ this one's all about nal_hevc_read_filler — and yes it's a whole vibe.

🌸 NAME 🌸

nal_hevc_read_filler — read filler data RBSP 🎀

---

✨ SYNOPSIS ✨

ssize_t nal_hevc_read_filler (const struct device *dev , void *src ,
       size_t n );

---

🦋 ARGUMENTS 🦋

• dev — device pointer, literally just the device you're working with 💖
• src — the buffer with RBSP data that is read, that's the one getting looked at 👀
• n — maximum size of src that shall be read, like the hard cap, no cap 🧢

---

💜 DESCRIPTION 💜

okay so what this does: it reads a filler data RBSP from src, up to a max of n bytes, and then returns the size of the filler data in bytes including the marker. iconic behavior honestly 🌟

This function is used to parse filler data and skip the respective bytes in the RBSP data. so it peeks, it counts, and it yeets past the boring bits 💅

The RBSP format of the filler data is specified in Rec. ITU-T H.265 (02/2018) 7.3.2.8 Filler data RBSP syntax. like, that's the receipts, go read the spec if you want the lore 📜

---

🌈 RETURN 🌈

number of filler data bytes (including marker) — or a negative error 😭 (bestie the marker counts, don't forget the marker 🫶)
