__video_dev...peline_start(9)

okay bestie, welcome to the Kernel API Manual page for __video_device_pipeline_start — the header does its little abbreviating thing and says __video_dev...peline_start(9), iconic behavior honestly 💅

🌸 NAME 🌸

__video_device_pipeline_start — mark a pipeline as streaming ✨

🦋 SYNOPSIS 🦋

int __video_device_pipeline_start (struct video_device *vdev , struct
       media_pipeline *pipe );

🎀 ARGUMENTS 🎀

• vdev — the starting video device. this is the device where the whole pipeline moment begins, periodt.
• pipe — the media pipeline to be assigned to all entities in the pipeline. every entity in the pipeline gets this one, no cap.

💖 DESCRIPTION 💖

🚨 note: This is the non-locking version of video_device_pipeline_start.

okay so this is the non-locking one — keep that in mind, bestie, because that detail is literally the whole vibe check here.

The video device must contain a single pad. not zero, not a whole collection, a single pad — that's the rule, fr fr 🫶

This is a convenience wrapper around __media_pipeline_start. so it's giving helpful little wrapper energy, not a whole new universe 🌈
