This is the central type that manages capturing of media on the local device.
Connect a camera and a microphone to a CaptureSession by assigning Camera and AudioInput objects to the relevant properties.
捕獲屏幕通過連接 ScreenCapture 對象到 screenCapture 特性。
捕獲窗口通過連接 WindowCapture 對象到 windowCapture 特性。
Enable a preview of the captured media by assigning a VideoOutput element to the videoOutput 特性。
Route audio to an output device by assigning an AudioOutput 對象到 audioOutput 特性。
Capture still images from a camera by assigning an ImageCapture 到 imageCapture 特性。
錄製音頻/視頻通過賦值 MediaRecorder 到錄製器特性。
CaptureSession { id: captureSession camera: Camera { id: camera } imageCapture: ImageCapture { id: imageCapture } recorder: MediaRecorder { id: recorder } videoOutput: preview Component.onCompleted: { camera.start() } }
注意： To ensure the camera starts capturing video frames on all platforms, explicitly call camera.start(), typically in the Component.onCompleted handler.
