STRUCT VDEC_PIC_INFO(9)

👑 struct vdec_pic_info(9) 👑

okay so bestie, welcome to the kernel API manual — we're looking at struct vdec_pic_info, which is literally just... picture size information. that's the whole vibe. it's giving "small struct, big responsibility" 💅

---

✨ NAME ✨

struct vdec_pic_info — picture size information 🖼️

---

🌸 SYNOPSIS 🌸

struct vdec_pic_info {
    unsigned int pic_w;
    unsigned int pic_h;
    unsigned int buf_w;
    unsigned int buf_h;
    unsigned int fb_sz[VIDEO_MAX_PLANES];
    unsigned int cap_fourcc;
    unsigned int reserved;
 };

no cap, that's the whole struct. seven members. count 'em. 🔥

🎀 Members 🎀

• pic_w — picture width, bestie. the actual width of the pic 📏
• pic_h — picture height. yeah, it's the vertical one 🦋
• buf_w — picture buffer width, which is pic_w rounded up to 64. so if your pic is a weird size, the buffer's gonna be a nice aligned 64-multiple, periodt ✨
• buf_h — picture buffer height, and yep, it's pic_h aligned up to 64 too. same energy 🫶
• fb_sz — bitstream size of each plane. it's an array, VIDEO_MAX_PLANES of them, iykyk. example time: suppose the picture size is 176x144 — then the buffer size gets aligned to 176x160. the way that 144 just becomes 160 😭 iconic behavior honestly
• cap_fourcc — the fourcc number. and lowkey important: it may change on a resolution change 👀 so don't go assuming it's frozen forever
• reserved — this one's just here to align the struct to 64-bit, so everything plays nice between 32-bit and 64-bit os. it's the peacekeeper of the group chat 🧚

ngl this struct is tiny but she's carrying the whole picture-size situation on her back. respect her 🫡

and that's a wrap, babe! this page came from ./drivers/media/platform/media..., dated October 2026 — and it's the struct vdec_pic_info(9) page, so you always know where to find her again when you forget what buf_w does. mwah 💋💖
