Summary

Allow users to select which camera device the QR scanner uses.

Upstream Issue

https://github.com/Donkie/Spoolman/issues/693

Problem

QR scanner defaults to first available camera device. When virtual cameras (OBS, etc.) are installed, they may be selected instead of the actual webcam. No way to switch cameras after initial permission grant.

Proposed Solution

1. Camera Selector Dropdown

Show all available video input devices in QR Scanner modal
Let user select preferred camera
Use navigator.mediaDevices.enumerateDevices()

2. Persist Selection

Store selected device ID in localStorage
Remember preference across sessions
Fall back to first device if saved device unavailable

Implementation

// Get available cameras
const devices = await navigator.mediaDevices.enumerateDevices();
const cameras = devices.filter(d => d.kind === "videoinput");

// Show dropdown with camera labels
// Save selection to localStorage
