STRUCT MEDIA_PIPELINE_PAD(9)

💅 struct media_pipeline_pad(9) — Kernel API Manual 🎀

okay so bestie, we're in the Kernel API Manual today and the main character is a lil struct that literally just holds a pad's connection to a pipeline. ngl, it's giving "small but booked and busy" ✨

---

🌸 NAME 🌸

struct media_pipeline_pad — a pad part of a media pipeline 🫶

---

✨ SYNOPSIS ✨

struct media_pipeline_pad {
    struct list_head list;
    struct media_pipeline *pipe;
    struct media_pad *pad;
 };

like, that's the whole vibe. three members, zero drama. 💅

---

💖 Members 💖

• list — bestie this is the entry in the media_pad pads list 📋
• pipe — the media_pipeline that the pad is part of 🚰
• pad — the media pad itself. the moment. the icon. 👑

---

🦋 Description 🦋

So this structure associates a pad with a media pipeline — it's literally the little friendship bracelet linking them together 💞

Instances of media_pipeline_pad are created by media_pipeline_start when it builds the pipeline, and then stored in the media_pad.pads list. so yeah, media_pipeline_start is the one doing the matchmaking 😌

And then media_pipeline_stop removes the entries from the list and deletes them. it's giving "we had a good run, but this is goodbye" 😭 periodt, no leftover copies, nothing lingering. clean break energy fr fr 🧹

lowkey that list is a whole mood board of media subsystem functions 😭 but every single one of them is right there, no cap. go read them, bestie, you got this 💜
