title: How can I add a missing PyQt5 modules on Raspberry Pi
body: <p>I am using PyQt5 version 5.7, python 3.5.3 and raspbian. My problem is that in my code some modules of PyQt5 get recognized and produce no error and some do.</p>
  
  <p>The error I get: <em>ImportError: cannot import name 'QMultimedia'</em></p>
  
  <p>So why does QtCore/Widgets/Gui get reconized but not QMultimedia? Do I need to install some extra packages? Do I need to reinstall and do something special? This might be a trivial question but please help me.</p>
  
  <p>Note: I also tried: <code>from PyQt5 import QtMultimedia</code></p>
  
  <pre><code>import numpy as np
  import sys
  from PyQt5 import QtCore
  from PyQt5 import QtWidgets
  from PyQt5 import QtGui
  from PyQt5 import QMultimedia
  from PyQt5 import QCameraInfo
  from PyQt5 import QVideoWidget
  from PyQt5 import QMediaObject
  from PyQt5.QtCore import pyqtSignal
  
  class Camera():
      def iniCamera():
          cam = QCamera()
          caminfo = QCameraInfo(cam)
          print (caminfo.description)
  
          if caminfo.isNull() != True:
             cam = QCamera(caminfo.deviceName())
             print (caminfo.description)
  
  if __name__ == '__main__':
  
      iniCamera()
  </code></pre>
