STRUCT VENC_H264_VPU_CONFIG_EXT(9)

🌸 NAME 🌸

okay so this is the struct venc...u_config_ext(9) page in the Kernel API Manual, and it's literally the Structure for h264 encoder configuration. The page also drops these access hints, iykyk: AP-W/R : AP is writer/reader on this item, and VPU-W/R: VPU is write/reader on this item. 💅

✨ SYNOPSIS ✨

Here's the whole struct, bestie — no cap, copy it exactly:

       struct venc_h264_vpu_config_ext {
           u32 input_fourcc;
           u32 bitrate;
           u32 pic_w;
           u32 pic_h;
           u32 buf_w;
           u32 buf_h;
           u32 gop_size;
           u32 intra_period;
           u32 framerate;
           u32 profile;
           u32 level;
           u32 wfd;
           u32 max_qp;
           u32 min_qp;
           u32 reserved[8];
        };

🧚 Members 🧚

vibe check the members, bestie — every single one is iconic in its own way:

• input_fourcc — input fourcc, periodt.
• bitrate — target bitrate (in bps). 💸
• pic_w — picture width. Picture size is visible stream resolution, in pixels, to be used for display purposes; must be smaller or equal to buffer size. So yes, it has to fit inside the buffer, no cap.
• pic_h — picture height.
• buf_w — buffer width. Buffer size is stream resolution in pixels aligned to hardware requirements.
• buf_h — buffer height.
• gop_size — group of picture size (idr frame).
• intra_period — intra frame period.
• framerate — frame rate in fps.
• profile — as specified in standard.
• level — as specified in standard.
• wfd — WFD mode 1:on, 0:off.
• max_qp — max quant parameter.
• min_qp — min quant parameter.
• reserved — reserved configs. (And in the synopsis it's reserved[8], just saying. 💅)
