title: Do I need MediaDevices permissions to take screenshots at intervals?
body: <p>Regarding the MediaDevices API.</p>

  <p>I know I need permission to use a media device to capture video, however I am not sure if I need to request permission multiple times in order to capture videoshots at regular intervals or just the one time at the start?</p>
  <p>In other words, when does the permission expire? When the stream is closed, browser is refreshed or something else?</p>
  <p>Can I use the initial permission to capture subsequent videoshots or do I need permission for each videoshot I intend to capture.</p>
