💅 v4l2_h264_in...list_builder(9) — the Kernel API Manual, bestie edition ✨

okay so real talk, this is a page from the Kernel API Manual and honestly? it's a little legend. it does one job and it does it slayfully: getting a reference list builder ready to go for P/B0/B1 lists. no cap.

🌸 NAME 🌸

v4l2_h264_init_reflist_builder — initialize a P/B0/B1 reference list builder 🎀

like, it's the setup era. the builder isn't building anything yet, it's just getting its whole life together first.

---

✨ SYNOPSIS ✨

void v4l2_h264_init_reflist_builder (struct v4l2_h264_reflist_builder *b
, const struct v4l2_ctrl_h264_decode_params *dec_params , const struct
v4l2_ctrl_h264_sps *sps , const struct v4l2_h264_dpb_entry
dpb[V4L2_H264_NUM_DPB_ENTRIES] );

it returns void btw — it's giving "i don't owe you a return value, i owe you a vibe." 💜

---

🦋 ARGUMENTS 🦋

• b — the builder context you're about to initialize. this is the main character of the function, lowkey. hand it over and it gets set up. 👑
• dec_params — the decode parameters control. it's the control with all the decode deets. 🍓
• sps — the SPS control. yes bestie, that SPS. 🎀
• dpb — the DPB to use when creating the reference list. type is struct v4l2_h264_dpb_entry dpb[V4L2_H264_NUM_DPB_ENTRIES], so it's the whole array, not a single entry — read the brackets, i beg 😭

🔥 SEE ALSO 🔥

• Kernel file ./drivers/media/v4l2-core/v4l2-h264.c
• v4l2_h264_build_p_ref_list(9)
• v4l2_h264_build_b_ref_lists(9)

the two buddies above are the ones who actually do the building, fyi — this page is just the intro era 🫶

ngl, this page is short and sweet. every detail above is the whole page, so if you skim it you literally got the whole thing. ate and left no crumbs 💅

---

and that's the whole thing, bestie! 🌈 this came out of ./drivers/media/v4l2-core, dated October 2026, and it lives at v4l2_h264_in...list_builder(9) in the Kernel API Manual. mwah, go forth and build those reference lists ✨💖🧚
