💅 pxa_camera_start_capture(9)

okay bestie, welcome to the Kernel API Manual 🎀 — this one's a lil function from the kernel docs and honestly it's giving "short but iconic." Let's get into it ✨

---

🌸 NAME 🌸

pxa_camera_start_capture — start video capturing 🎥✨

---

🦋 SYNOPSIS 🦋

void pxa_camera_start_capture (struct pxa_camera_dev *pcdev );

---

💖 ARGUMENTS 💖

• pcdev — the camera device 👑 (that's your main character right there)

---

⭐ DESCRIPTION ⭐

So like, this is the "launch capturing" moment bestie 🚀 — it kicks the whole capture thing off.

But here's the vibe check: your DMA channels should not be active yet 🙈. No cap, they're supposed to still be chilling. They get activated at the end of frame interrupt, and the reason is lowkey genius — that way you capture only whole frames 💯, and you never start capturing a partial frame. Not even a little sliver. Not on our watch 💅

fr fr, don't go activating those DMA channels early — the whole point is whole frames only 🫶
