Detailed Description#

The QMediaCaptureSession is the central class that manages capturing of media on the local device.

You can connect a video input to QMediaCaptureSession using setCamera() , setScreenCapture() or setWindowCapture() . A preview of the captured media can be seen by setting a QVideoWidget or QGraphicsVideoItem using setVideoOutput() .

You can connect a microphone to QMediaCaptureSession using setAudioInput() . The captured sound can be 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 .
