I am using Qtmultimedia 5.0 to record and capture video from webcam. The example provided by Qt helped me very much. I could record and stop the captured video using the following code.

Qt Code: 
  1. Camera {
  2.     id: camera
  3.     }
  4.  
  5.     Rectangle{
  6.     Text{
  7.     text: qsTr("Record")
  8.     }
  9.     MouseArea{
  10.     onClicked: camera.videoRecorder.record()
  11.  
  12.     }
  13.     }
  14.  
  15.     Rectangle{
  16.     Text{
  17.     text: qsTr("Stop")
  18.     }
  19.     MouseArea{
  20.     onClicked: camera.stop()
  21.  
  22.     }
  23.     }
To copy to clipboard, switch view to plain text mode 

i need the pause and resume the webcam video.By default the recorded video is saved in mkv format. file is being closed when i use camera.stop(). when camera.start() is called ,it is saving in new file. I need to append the current video to the previously recorded video. pls help.
