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