The QMediaCaptureSession is the central class that manages capturing of media on the local device.
You can connect a camera and a microphone to QMediaCaptureSession using setCamera() and setAudioInput(). A preview of the captured media can be seen by setting a QVideoSink of QVideoWidget using setVideoOutput() and heard by routing the audio to an output device using setAudioOutput().
You can capture still images from a camera by setting a QImageCapture object on the capture session, and record audio/video using a QMediaRecorder.

This property holds the camera used to capture video.
Record video or take images by adding a camera to the capture session using this property,
Access functions:
| QCamera * | camera() const |
| void | setCamera(QCamera *camera) |
Notifier signal:
| void | cameraChanged() |
This property holds the object used to capture still images.
Add a QImageCapture object to the capture session to enable capturing of still images from the camera.
Access functions:
| QImageCapture * | imageCapture() |
| void | setImageCapture(QImageCapture *imageCapture) |
Notifier signal:
| void | imageCaptureChanged() |
This property holds the recorder object used to capture audio/video.
Add a QMediaRecorder object to the capture session to enable recording of audio and/or video from the capture session.
Access functions:
| QMediaRecorder * | recorder() |
| void | setRecorder(QMediaRecorder *recorder) |
Notifier signal:
| void | recorderChanged() |
Creates a session for media capture from the parent object.
[virtual] QMediaCaptureSession::~QMediaCaptureSession()Destroys the session.
Returns the device that is being used to capture audio.
Note: Getter function for property audioInput.
See also setAudioInput().
Sets the audio input device to input. If setting it to an empty QAudioDevice the capture session will use the default input as defined by the operating system.
Note: Setter function for property audioInput.
See also audioInput().
Sets the audio output device to output.
Note: Setter function for property audioOutput.
See also audioOutput().
Sets a QObject, (output), to a video preview for the capture session.
A QObject based preview is expected to have an invokable videoSink() method that returns a QVideoSink.
The previously set preview is detached.
Note: Setter function for property videoOutput.
See also videoOutput().
Sets a QVideoSink, (sink), to a video preview for the capture session.
A QObject based preview is expected to have an invokable videoSink() method that returns a QVideoSink.
The previously set preview is detached.
