v4l2_dv_timi...aspect_ratio(9)

🌸 hey bestie, welcome to the v4l2_dv_timi...aspect_ratio(9) page 🌸

okay so this is from the Kernel API Manual, and before you panic at the truncated-looking title — yes, that's genuinely how it's written up top, the full function name is right below and it's v4l2_dv_timings_aspect_ratio, we love an abbreviation moment 💅

✨ NAME ✨

v4l2_dv_timings_aspect_ratio — literally calculates the aspect ratio based on the v4l2_dv_timings information. that's it, that's the whole gig. iconic behaviour honestly 🎀

---

🦋 SYNOPSIS 🦋

struct v4l2_fract v4l2_dv_timings_aspect_ratio (const struct v4l2_dv_timings *t );
