getDevices()

static getDevices(refresh): Promise<CameraDeviceInfo[]>

Defined in: packages/core/src/camera/camera-utils.ts:37

• Caches results for subsequent calls

On subsequent calls with refresh=false:

• Returns cached results immediately

Parameters

refresh

boolean = false

Force re-enumeration (useful for hot-plugged devices)

Returns

Promise<CameraDeviceInfo[]>

Array of available camera devices
