media_pipeline_alloc_start(9)

💅 media_pipeline_alloc_start(9) 💅

okay so this little page comes straight from the Kernel API Manual, and it's all about media_pipeline_alloc_start — the function whose whole job is to mark a pipeline as streaming. iconic behavior, honestly. 🎀

🌸 NAME 🌸

media_pipeline_alloc_start — mark a pipeline as streaming. periodt. 💖

✨ SYNOPSIS ✨

int media_pipeline_alloc_start (struct media_pad *pad );

🫶 ARGUMENTS 🫶

• pad — the starting pad, bestie. that's the pad you're handing in. 🦋

💅 DESCRIPTION 💅

So media_pipeline_alloc_start is lowkey similar to media_pipeline_start, but the way it moves is different: instead of working on a given pipeline, it will use an existing pipeline if the pad is already part of a pipeline, or it will allocate a new pipeline. no cap, that's the whole vibe. ✨

Calls to media_pipeline_alloc_start must be matched with media_pipeline_stop. like, this is not a “forget to clean up” situation, bestie — match them. fr fr. 💀
