v4l2_fill_pix_format(9)

✨ v4l2_fill_pix_format(9) ✨

okay bestie, welcome to the Kernel API Manual 💅 this one lives in the media subsystem and it's lowkey a little matchmaker function — it takes your media-bus format and translates it into a pixel format. it's giving "glow-up," fr fr. 🦋

---

🌸 NAME 🌸

v4l2_fill_pix_format — an ancillary routine (yes, ancillary, she's a supporting character but she ATE 🎀) that fills a &struct v4l2_pix_format's fields from a &struct v4l2_mbus_framefmt.

that's it. that's the whole job. copy the vibe from one struct to the other. no cap. ✨

---

🧚 SYNOPSIS 🧚

void v4l2_fill_pix_format (struct v4l2_pix_format *pix_fmt , const
struct v4l2_mbus_framefmt *mbus_fmt );

notice she returns void — she's not here to give you feedback, she's here to do the thing. 🔥

---

💖 ARGUMENTS 💖

• pix_fmt — pointer to struct v4l2_pix_format to be filled 🫶 this is the one getting the makeover. she shows up empty-handed and leaves iconic.
• mbus_fmt — pointer to struct v4l2_mbus_framefmt to be used as model 👑 this is the reference photo. the inspo. the mood board. pix_fmt is gonna copy her whole look.

ok so quick vibe check: pix_fmt = the destination, mbus_fmt = the source of truth. don't mix them up, bestie 😭
