video_device_pipeline_stop(9)

💅 video_device_pipeline_stop(9)

okay bestie, welcome to the Kernel API Manual ✨ this one's a little function with a big job and honestly? she's giving cleanup crew energy 🧹💖

---

🌸 NAME

video_device_pipeline_stop — mark a pipeline as not streaming 💀

---

🎀 SYNOPSIS

void video_device_pipeline_stop (struct video_device *vdev );

---

🦋 ARGUMENTS

• vdev — the starting video device, aka where you begin the walk 🌈

---

✨ DESCRIPTION

okay so here's the vibe: this function marks all the entities connected to a given video device as not streaming — and that's either directly or indirectly, but only through enabled links. no enabled link, no invite to the party 🙈 and the media_pad pipe field gets reset to NULL. periodt.

and here's the part you cannot skip, bestie 👑 if multiple calls to media_pipeline_start have been made, you need the same number of calls to this function to actually mark the pipeline as not streaming. it's a 1:1 ratio situation, very demure, very balanced 🫶

also: the video device must contain a single pad. one pad. that's the rule. no cap.

and for the record, this whole thing is a convenience wrapper around media_pipeline_stop — she's not doing the heavy lifting herself, she's just the friendly face at the front desk 💅

⚠️ reminder that the counting thing is real: mismatched start/stop calls and your pipeline stays streaming. keep your little ledger, iykyk ✨
