SDL_HINT_CAMERA_DRIVER(3)

💖 SDL_HINT_CAMERA_DRIVER 💖

okay bestie, so this one lives in the SDL3 FUNCTIONS corner of the SDL_HINT_CAMERA_DRIVER(3) manual, and it's literally just a little variable that picks which camera backend you're running with. yes, that's the whole vibe. let's get into it 🎀

---

✨ NAME ✨

SDL_HINT_CAMERA_DRIVER — a variable that decides what camera backend to use. that's it, that's the girl 💅

---

🌸 SYNOPSIS 🌸

#include <SDL3/SDL_hints.h>

#define SDL_HINT_CAMERA_DRIVER "SDL_CAMERA_DRIVER"

copy that exactly, don't freestyle it 🫶

🦋 DESCRIPTION 🦋

So here's the tea. By default, SDL is gonna try all the available camera backends, in a reasonable order, until it finds one that can actually work. very "try everything until something hits" of it, we love the effort.

But! This hint lets the app or the user force a specific target instead. like, say you're on Windows Media Foundations but you wanna try DirectShow instead — boom, you just set it to "directshow" and go. main character energy, choosing your own backend 😌

The default value is unset, in which case SDL will try to figure out the best camera backend on your behalf. it's giving helpful, honestly.

🚨 important bestie: this hint needs to be set before SDL_Init() is called to be useful. before, okay?? not during, not after, before. timing is everything, no cap 🕐

---

🌈 AVAILABILITY 🌈

This hint is available since SDL 3.2.0. so if you're on something older... girl, upgrade 💀

and that's the whole page, periodt ✨
