STRUCT MTK_ENC_PARAMS(9)

💅 struct mtk_enc_params(9) 💅

okay bestie, welcome to the Kernel API Manual — this page is literally all about struct mtk_enc_params, no cap ✨

🌸 NAME 🌸

struct mtk_enc_params — the general encoding parameters, aka the whole vibe sheet for your encoder 🎀

✨ SYNOPSIS ✨

struct mtk_enc_params {
    unsigned int    bitrate;
    unsigned int    num_b_frame;
    unsigned int    rc_frame;
    unsigned int    rc_mb;
    unsigned int    seq_hdr_mode;
    unsigned int    intra_period;
    unsigned int    gop_size;
    unsigned int    framerate_num;
    unsigned int    framerate_denom;
    unsigned int    h264_max_qp;
    unsigned int    h264_profile;
    unsigned int    h264_level;
    unsigned int    force_intra;
};

look at her. thirteen unsigned ints. main character energy fr fr 👑

🦋 Members 🦋

• bitrate — the target bitrate, measured in bits per second. that's the goal, the dream, the number we're chasing 💖
• num_b_frame — how many b frames sit between p-frames. that's it, that's the field 🫶
• rc_frame — frame based rate control. rate control, but make it per-frame ✨
• rc_mb — macroblock based rate control. same energy, way finer granularity, we're zooming in 🔍
• seq_hdr_mode — decides whether the H.264 sequence header gets encoded separately or joined with the first frame. two paths, one field, iykyk 💅
• intra_period — the I frame period. how often we drop an intra frame, basically 🌈
• gop_size — group of picture size, and bestie it's used as the intra frame period. yes she's doing double duty, we love a multitasker 👑
• framerate_num — frame rate numerator. example time: framerate_num=30 and framerate_denom=1 means FPS is 30 🍓
• framerate_denom — frame rate denominator. same example, same energy: framerate_num=30 and framerate_denom=1 means FPS is 30 🧚
• h264_max_qp — max value for the H.264 quantization parameter. it's giving ceiling 🔥
• h264_profile — the H.264 profile, as defined by V4L2 ⭐
• h264_level — the H.264 level, as defined by V4L2 ⭐
• force_intra — force or insert an intra frame. yes ma'am, on demand 💀
