nal_hevc_level(9)

💖 nal_hevc_level(9) 💖

okay so real talk, bestie — we're in the Kernel API Manual today (yes, the nal_hevc_level(9) page, that's our girl), and this one is a tiny little function that does exactly one thing and does it flawlessly. main character energy, no notes ✨

---

🌸 SYNOPSIS 🌸

int nal_hevc_level (enum v4l2_mpeg_video_hevc_level level );

like, that's it. that's the whole vibe. 🎀

---

💅 ARGUMENTS 💅

• level — the level, and it's typed as an enum v4l2_mpeg_video_hevc_level. so you hand her the enum, she knows what to do with it. slay 🫶

---

🎀 DESCRIPTION 🎀

so what does she actually do? she converts the enum v4l2_mpeg_video_hevc_level into a level_idc, and the level_idc she gives you back is exactly the one specified in Rec. ITU-T H.265 (02/2018) A.4.1. — yes the spec, yes that section, yes she read it so you don't have to 💀

it's giving "glorified lookup table but make it iconic" and honestly? we love her for it. no cap, that's the entire function. ✨

---

🦋 RETURN 🦋

she returns the level_idc for the passed level. that's the return value. that's the whole deal. 🍓
