  You are playing 30s of media in 5s (i.e. the file will be played back
6 times faster).

  You are playing 50s of media in 6s (i.e. the file will be played back
50/6 times faster).


  In addition to that, no sound will be outputted for the first 2s
(since your start values are 2 * GST_SECOND).

  You might want to debug your aplication by first using:
  'start' to 0
  'media-duration' and 'duration' to the same values (resulting in
regular playback speed)
