  65 Plays an audio stream at a different speed (by resampling the audio).
  66 </p>
  67 <p>
  68 Do not use this element. Either use the 'pitch' element, or do a seek with
  69 a non-1.0 rate parameter, this will have the same effect as using the speed
  70 element (but relies on the decoder/demuxer to handle this correctly, also
  71 requires a fairly up-to-date gst-plugins-base, as of February 2007).
