video_device_pipeline(9)

💅 video_device_pipeline(9) — a Kernel API Manual moment

okay so bestie, welcome to the video_device_pipeline(9) page, brought to you by the Kernel API Manual. this one's short and sweet — it's giving "small function, big pipeline energy" ✨

---

🌸 NAME 🌸

video_device_pipeline — get the media pipeline a video device is part of 🎀

---

🦋 SYNOPSIS 🦋

struct media_pipeline * video_device_pipeline (struct video_device *vdev
);

like yes, that's the whole signature, she's compact 💅

---

🍓 ARGUMENTS 🍓

• vdev — the video device. that's it, that's the vibe check 🌈

---

✨ DESCRIPTION ✨

okay so here's the tea 🫖 — this function returns the media pipeline that a video device has been associated with when you constructed the pipeline with video_device_pipeline_start.

the pointer stays valid until video_device_pipeline_stop is called. that's the deal, no cap — after the stop, don't go touching it 😭

also important: the video device must contain a single pad. one pad. not two. not zero. one. 👑

and ngl, this one is just a convenience wrapper around media_entity_pipeline — it's literally the shortcut bestie so you don't have to do it the long way 🧚

---

🔥 RETURN 🔥

it hands you back the media_pipeline the video device is part of 💖

but if the video device is not part of any pipeline? you get NULL. no pipeline, no pointer, no problem 💀
