mtk_vdec_h26...ecode_params(9)

okay so bestie, welcome to the mtk_vdec_h26...ecode_params(9) page in the Kernel API Manual ✨ this one is short, iconic, and very “just the essentials” — no cap 💅

🌸 NAME 🌸

mtk_vdec_h264_copy_decode_params — get decode params. that’s the whole vibe 🫶

✨ SYNOPSIS ✨

here’s the signature, exactly as the kernel girlies wrote it:

       void mtk_vdec_h264_copy_decode_params (struct
       slice_api_h264_decode_param *dst_params , const struct
       v4l2_ctrl_h264_decode_params *src_params , const struct
       v4l2_h264_dpb_entry dpb[V4L2_H264_NUM_DPB_ENTRIES] );

it returns void, so there’s literally no return value to obsess over 😌

🎀 ARGUMENTS 🎀

• dst_params — dst params for hw decoder, slay 💖
• src_params — decode params from user driver, exactly that ✨
• dpb — dpb information, iconic 🎀
