Description
Plays an audio stream at a different speed (by resampling the audio).
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).
Example launch line
1 |
gst-launch-1.0 filesrc location=test.ogg ! decodebin ! audioconvert ! speed speed=1.5 ! audioconvert ! audioresample ! autoaudiosink |
Plays an .ogg file at 1.5x speed.
