vimc_streamer_s_stream(9)

💖 vimc_streamer_s_stream — the Kernel API Manual, bestie edition 💖

okay so this page is vimc_streamer_s_stream(9), straight out of the Kernel API Manual, and it's literally the on/off switch for streaming on the media pipeline. one function, two jobs, zero drama. let's go ✨

---

🌸 NAME 🌸

vimc_streamer_s_stream — start/stop the streaming on the media pipeline. that's it, that's the whole vibe 🎀

---

✨ SYNOPSIS ✨

int vimc_streamer_s_stream (struct vimc_stream *stream , struct
       vimc_ent_device *ved , int enable );

like, it returns an int, takes three things, and it is not subtle about any of them 💅

---

🦋 ARGUMENTS 🦋

• stream — the pointer to the stream structure of the current stream. yes, the stream's stream struct, we love a self-referential moment 👑
• ved — pointer to the vimc entity of the entity of the stream. (the original says "of the entity of the entity", and honestly? iconic. we keep it fr fr 🫶)
• enable — flag to determine if the stream should start/stop. it's giving toggle energy. main character boolean ⭐

---

🧚 DESCRIPTION 🧚

okay so when you're starting, first thing it does is check if there is no stream->kthread allocated. no cap, that check is there because a missing stream->kthread should indicate that a stream is already running. read it twice, it's fine, the manpage said it 😭

then it initializes the pipeline, and creates and runs a kthread to consume buffers through the pipeline. a whole little thread, working hard, consuming buffers, no thoughts head empty 🦋

when you're stopping, it does the analogous thing: check if there is a stream running, stop the thread, and terminate the pipeline. symmetric, clean, ate 💅

---

🔥 RETURN 🔥

• 0 if success 🎉
• error code otherwise 💀
