v4l2_video_std_frame_period(9)

💅 NAME 💅

v4l2_video_std_frame_period — okay so this is an ancillary routine, and what it does is literally fill a struct &v4l2_fract pointer with the default framerate fraction. That's the whole vibe. 🎀

✨ SYNOPSIS ✨

void v4l2_video_std_frame_period (int id , struct v4l2_fract
*frameperiod );

🫶 ARGUMENTS 🫶

• id — the analog TV standard ID. bestie, it's giving "which broadcast norm are we on" energy 📺
• frameperiod — a struct v4l2_fract pointer, and it's the one getting filled. not to be dramatic but it's the main character of this whole function ngl 🌟

fr fr go read those if you wanna understand the whole friend group — this one is just the lowkey little helper handing you a default framerate fraction and dipping 🙈
