STRUCT MEDIA_PIPELINE(9)

🦋 struct media_pipeline(9) 🦋

okay bestie, welcome to the glow-up era of struct media_pipeline(9) — straight out of the Kernel API Manual, no cap. it's the little struct that holds all the media pipeline related information, and honestly? it's giving backstage-pass energy. 💅

---

✨ NAME ✨

struct media_pipeline — Media pipeline related information 🎀

---

🌸 SYNOPSIS 🌸

struct media_pipeline {
    bool allocated;
    struct media_device *mdev;
    struct list_head pads;
    int start_count;
};

look at her. four fields. immaculate. 🌈

---

💖 Members 💖

• allocated — Media pipeline allocated and freed by the framework ✨ like, she doesn't book her own hotel room, the framework handles that for her, periodt
• mdev — The media device the pipeline is part of 🫶 that's her home base, the device she belongs to
• pads — List of media_pipeline_pad 📋 yup, a whole list of them, that's the vibe
• start_count — Media pipeline start - stop count 🔢 literally what it says: the start/stop counter, keeping tally like a main character with a notes app

bestie that's a LOT of cross-references and yes you should read the relevant ones before you go poking at pipelines, i'm just being honest with you 🫶

and that's the whole page, mwah 💋 — this edition came from ./include/media, dated October 2026, and it's brought to you by the Kernel API Manual. slay, go read some kernel headers now. 💜🎀
