STRUCT GSC_FRAME(9)

💅 NAME

struct gsc_frame — bestie, this is literally the source/target frame properties struct ✨

It's a manual page from the Kernel API Manual, and we're gonna get you so comfy with it 🫶

✨ SYNOPSIS

struct gsc_frame {
    u32 f_width;
    u32 f_height;
    struct v4l2_rect crop;
    unsigned long payload[VIDEO_MAX_PLANES];
    struct gsc_addr addr;
    const struct gsc_fmt *fmt;
    u32 colorspace;
    u8 alpha;
 };

No cap, that's the whole vibe. Now let's meet the members 💖

🎀 Members

• f_width — okay so width has two moods depending on where you are: on SRC it's SRCIMG_WIDTH, and on DST it's OUTPUTDMA_WHOLE_IMG_WIDTH. Same girl, different era 💅
• f_height — and height is matching energy fr fr: SRC : SRCIMG_HEIGHT, DST : OUTPUTDMA_WHOLE_IMG_HEIGHT 🦋
• crop — the cropped size when you're the source, and the scaled size when you're the destination 🎀 it's giving glow-up by scaling
• payload — the image size in bytes (that's w x h x bpp, iykyk) and it's an array of VIDEO_MAX_PLANES of type unsigned long 🔥
• addr — the image frame buffer physical addresses, aka where the pixels actually live 🏠✨
• fmt — a G-Scaler color format pointer, typed const struct gsc_fmt * 👑
• colorspace — a value indicating v4l2_colorspace 🌈
• alpha — the frame's alpha value, a little u8 doing big things 💜
