STRUCT VDEC_HEVC_SLICE_LAT_DEC_PARAM(9)

🌸 NAME 🌸

okay so bestie, welcome to the struct vdec_hevc_slice_lat_dec_param(9) page — this is a Kernel API Manual moment, and the whole vibe is: this struct holds all the parameters for decode current frame 💅✨

---

✨ SYNOPSIS ✨

the whole thing, exactly as it lives, no cap:

struct vdec_hevc_slice_lat_dec_param {
    struct mtk_hevc_sps_param sps;
    struct mtk_hevc_pps_param pps;
    struct mtk_hevc_slice_header_param slice_header;
    struct slice_api_hevc_scaling_matrix scaling_matrix;
    struct slice_api_hevc_decode_param decode_params;
    struct mtk_hevc_dpb_info
hevc_dpb_info[V4L2_HEVC_DPB_ENTRIES_NUM_MAX];
 };

like… six members and a whole array, she's got range 🫶

---

🎀 Members 🎀

• sps — the hevc sps syntax parameters. yes bestie, sps, she's here, she's syntax, she's parameters 💖
• pps — the hevc pps syntax parameters. pps said "i'm also iconic" and honestly? correct 👑
• slice_header — the hevc slice header syntax parameters. this one's giving "little header that could" ✨
• scaling_matrix — the hevc scaling list parameters. matrix era, lowkey obsessed 🌈
• decode_params — decoder parameters of each frame used for hardware decode. this is the one doing the actual work for the hardware, main character energy fr fr 🔥
• hevc_dpb_info — the dpb reference list. it's an array of struct mtk_hevc_dpb_info sized V4L2_HEVC_DPB_ENTRIES_NUM_MAX, so like… the whole reference list, slay 🦋

and the whole friend group, all at once:

• enum vdec_hevc_core_dec_err_type(9)
• struct mtk_hevc_dpb_info(9)
• struct hevc_fb(9)
• struct vdec_hevc_slice_info(9)

• struct vdec_hevc_slice_share_info(9)
• struct vdec_hevc_slice_inst(9)

ngl, if you're here it's probably because the hevc decoder path is doing something and you need to know what's in this struct. now you know 💀💖
