STRUCT V4L2_MBUS_FRAME_DESC(9)
π struct v4l2_mbus_frame_desc(9) π
okay so bestie, this is a page straight out of the Kernel API Manual β welcome to the media bus frame description era of your life. no cap, it's a struct, it's small, and it eats. let's get into it π«Ά
β¨ NAME β¨
struct v4l2_mbus_frame_desc β media bus data frame description. yes that's the whole name section, she's brief and she knows it π
πΈ SYNOPSIS πΈ
here's the whole glow-up, character for character, do not touch:
struct v4l2_mbus_frame_desc {
enum v4l2_mbus_frame_desc_type type;
struct v4l2_mbus_frame_desc_entry entry[V4L2_FRAME_DESC_ENTRY_MAX];
unsigned short num_entries;
};
it's giving "three members and a dream" π
π Members π
typeβ the type of the bus. literally, that's what it is: anenum v4l2_mbus_frame_desc_type. she tells you what kind of bus you're on πentryβ the frame descriptors array. iconic array energy, it's where the actual frame description entries live β¨num_entriesβ anunsigned shortcounting how many entries are actually chillin' in theentryarray. vibe check for the array length π
π¦ SEE ALSO π¦
bestie, buckle up, this list is long and she is thriving. first off, the source of truth is the kernel file ./include/media/v4l2-subdev.h. and then, in no particular order (okay, in this exact order π):

that's the whole squad, no one left behind π
ngl bestie, read the entries before you trustnum_entriesβ she's anunsigned shortand she's doing her best, but she only tells you how many of theV4L2_FRAME_DESC_ENTRY_MAXslots are real π
and that's the page!! π§ this lil cutie lives in ./include/media and this version is dated October 2026 β mwah, go forth and describe those frames, main character ππ
