💖 struct fimc_is_video(9) 💖

okay so this is the manual page for struct fimc_is_video(9) — yes the whole thing, and honestly? it's giving main character energy for the fimc-is video device. bestie, this struct is literally the blueprint for a video device, so let's get into it 🎀

✨ NAME ✨

struct fimc_is_video — the fimc-is video device structure, aka the whole vibe of a video device in one struct 💅

struct fimc_is_video {
    struct exynos_video_entity ve;
    enum v4l2_buf_type      type;
    struct media_pad        pad;
    struct list_head        pending_buf_q;
    struct list_head        active_buf_q;
    struct vb2_queue        vb_queue;
    unsigned int            reqbufs_count;
    unsigned int            buf_count;
    unsigned int            buf_mask;
    unsigned int            frame_count;
    int streaming;
    struct isp_video_buf    *buffers[FIMC_ISP_MAX_BUFS];
    const struct fimc_fmt   *format;
    struct v4l2_pix_format_mplane pixfmt;
 };

like, look at that field list. no cap, it ate 🍓

🦋 Members 🦋

here's the tea on every single field, no skipping, i promise 🫶

• ve — the video_device structure and the media pipeline, both of them, iconic combo ✨
• type — the video device type, so it's either CAPTURE or OUTPUT — pick your fighter 💀
• pad — the video device media (sink) pad 🎀
• pending_buf_q — the head of the pending buffers queue, they're just waiting their turn 💜
• active_buf_q — the queue head of buffers scheduled in hardware, like they're literally on stage rn 🔥
• vb_queue — the vb2 buffer queue 👑
• reqbufs_count — how many buffers you asked for in the REQBUFS ioctl, yes it counts them fr fr
• buf_count — the number of video buffers scheduled in hardware ⭐
• buf_mask — the bitmask of the queued video buffer indices, very bitmask, very slay 🌈
• frame_count — a counter of frames dequeued to user space, keeping tally bestie 😭
• streaming — is streaming in progress? the eternal question 🙈
• buffers — buffer info, that's it, that's the note 💖
• format — the current fimc pixel format 🌸
• pixfmt — the current pixel format, cousin of the one above ✨
