STRUCT VDEC_AV1_SLICE_FRAME_INFO(9)

🦋 NAME 🦋

struct vdec_av1_slice_frame_info — the frame info for each slot, bestie ✨ like every slot gets its own lil' info card and this is the card 💅

It lives in the Kernel API Manual, which is genuinely the main character of manual pages ngl 👑

💖 SYNOPSIS 💖

okay so here's the whole struct, and yes you're gonna look at all of it, no skipping 🫶

struct vdec_av1_slice_frame_info {
    u8 frame_type;
    u8 frame_is_intra;
    int order_hint;
    u32 order_hints[V4L2_AV1_REFS_PER_FRAME];
    u32 upscaled_width;
    u32 pic_pitch;
    u32 frame_width;
    u32 frame_height;
    u32 mi_rows;
    u32 mi_cols;
    int ref_count;
 };

🌸 Members 🌸

real talk, these fields are the whole vibe check of the page — every single one matters, so here's every single one 💜

• frame_type — the frame type. that's it, that's the field, it tells you what kind of frame you're dealing with 😌
• frame_is_intra — tells you if this is an intra frame 👀
• order_hint — the order hint, lowkey important for ordering things
• order_hints — the reference frame order hint (the original page spells it "referece" and honestly? iconic typo, we stan a legend 💀). it's an array sized V4L2_AV1_REFS_PER_FRAME, so it's giving "one hint per reference frame" energy ✨
• upscaled_width — the upscale width 🦋
• pic_pitch — the buffer pitch, fr fr
• frame_width — the frame width (fun fact: the original doc says "frane width" and I refuse to correct history 🎀)
• frame_height — the frame height, periodt
• mi_rows — rows in mode info 📏
• mi_cols — cols in mode info 📐
• ref_count — a mark to reference frame counts, iykyk 🔥

and that's the page, bestie 🎀 before you go — the lil' footer credits: this one comes from the source path ./drivers/media/platform/media... and it's dated October 2026, and the whole thing is filed under struct vdec_...e_frame_info(9) 💖 slay, go read some more kernel docs, I'm obsessed with you 🫶✨
