okay so bestie, welcome to the glow-up of v4l2_h264_build_b_ref_lists(9), brought to you by the Kernel API Manual, no cap 🫶

🌸 NAME 🌸

v4l2_h264_build_b_ref_lists — literally builds the B0/B1 reference lists. that's the whole vibe. 💖

---

✨ SYNOPSIS ✨

void v4l2_h264_build_b_ref_lists (const struct v4l2_h264_reflist_builder
*builder , struct v4l2_h264_reference *b0_reflist , struct
v4l2_h264_reference *b1_reflist );

she takes three args, returns void, and does not miss. periodt. 💅

🎀 ARGUMENTS 🎀

• builder — the reference list builder context. yes queen, this is the main character of the operation. 👑
• b0_reflist — a 32 sized array used to store the B0 reference list. every single entry in it is a v4l2_h264_reference structure. lowkey important. ✨
• b1_reflist — a 32 sized array used to store the B1 reference list. each entry is, you guessed it, a v4l2_h264_reference structure. she's giving symmetry. 🦋

🔥 DESCRIPTION 🔥

so what does she actually do? this function builds the B0/B1 reference lists. iconic behavior fr fr. 🌈

the whole procedure is described in section '8.2.4 Decoding process for reference picture lists construction' of the H264 spec — like, that's the receipt, that's the source material, go read it iykyk. 📖

this function can be used by H264 decoder drivers that need to pass B0/B1 reference lists to the hardware. that's the use case, that's the assignment, and she ate. 💀✨

• v4l2_h264_build_p_ref_list(9) — her sister function, also slaying 💜

ngl bestie, if you're writing an H264 decoder driver and you need those B0/B1 reference lists handed off to the hardware, this is the function. no notes. 🫶
