💅 v4l2_vp9_seg_feat_enabled 💅

okay so this is a page from the Kernel API Manual (yes, the Kernel API Manual, we're fancy now 🎀) and it's all about one tiny little helper that answers one tiny little question. bestie, it's giving "small function, big feelings" and honestly? iconic.

✨ NAME ✨

v4l2_vp9_seg_feat_enabled — check if a segmentation feature is enabled 👀💖

like literally. that's the whole job. it checks whether a feature is turned on for a segment. no cap.

---

🌸 SYNOPSIS 🌸

bool v4l2_vp9_seg_feat_enabled (const u8 *feature_enabled , unsigned int
feature , unsigned int segid );

so it hands you back a bool — true or false, yes or no, slay or not-slay 💅 — and you feed it a pointer plus two unsigned ints. that's the vibe check in code form fr fr.

---

🦋 ARGUMENTS 🦋

• feature_enabled — an array of 8-bit flags, and it covers all the segments. yes, all of them. it's the group chat of flags 🫶
• feature — the id of the feature you're checking. which one do you wanna know about, bestie? 🔍
• segid — the id of the segment you're looking up. which segment are we snooping on 💀

---

🌈 DESCRIPTION 🌈

okay so here's the tea ☕: this function returns true if a given feature is active in a given segment. that's it. that's the whole plot.

you pass in the flags array, the feature id, the segment id, and it tells you whether that feature is on for that segment. lowkey the most straightforward function in the whole kernel and honestly? we stan a clear communicator 👑✨

💜 SEE ALSO 💜

go touch some grass in the kernel file ./include/media/v4l2-vp9.h — that's where all the structs live 🧚 and then go say hi to all these besties:

• struct v4l2_vp9_frame_mv_context(9)
• struct v4l2_vp9_frame_context(9)
• struct v4l2_vp9_frame_symbol_counts(9)
• v4l2_vp9_fw_update_probs(9)
• v4l2_vp9_reset_frame_ctx(9)
• v4l2_vp9_adapt_coef_probs(9)
• v4l2_vp9_adapt_noncoef_probs(9)

that's the whole friend group, no one gets left out 💖🦋

---

ngl this one's short and sweet — but don't sleep on it, the details still matter: the array is 8-bit flags, the feature and segid args are unsigned int, and the return type is bool. that's the facts, periodt 🔥

and that's a wrap, bestie 🎀 this page lives over in ./include/media, it's stamped October 2026, and it comes to you from the Kernel API Manual v4l2_vp9_seg_feat_enabled(9) — mwah, go check some segmentation features 💅💜⭐
