Playback Rate

Playback rate tuning

You can easily provide your audience with playback rate change options, thanks to our intuitive playback rate player module. For more advanced use-cases our player API will let you build a custom user experience. The playback rate module is only available for video content (e.g. not for audio-only player) but the playback rate API can be used with the audio-only player as well.

Player settings

speed: Boolean

Activate or not the playback rate module. Default: false.

speedRates: Array

Set the playback rate available values to be used by the playback rate module. Must be submitted as an array of numbers. Default: [0.25, 0.5, 1, 1.5, 2, 4].

Playback rate API methods

getPlaybackRate()

rmp.getPlaybackRate();

This method returns a Number representing the current playback rate. -1 is returned if this value is not available.

setPlaybackRate(rate)

rmp.setPlaybackRate(2);

This method will change the player playback rate to the Number set as input parameter. Decent values for playback rate ranges from 0.25 to 4 and can be increment by 0.1. Values outside this range may cause playback issues in some browsers.
