Speed Selection plugin

With the Speed Selection plugin, you can add support for viewers to select playback speed within the player. Being able to select playback speed can enhance the viewing experience by improving accessibility, enhancing learning and productivity, and providing better control. To see the Speed Selection plugin in action, view this demo.

Before you start

Before you use this plugin with the standalone player, we recommend the following steps:

Read about embedding the core player in your site by adding the minimum CSS and JavaScript player components.
Make sure you have a player token. For more, see Token configuration . Tokens aren't needed for local development.
The instructions on this page generally assume you're using the Wowza Flowplayer CDN to embed the player in your site. If you're using npm, see our npm instructions or our TypeScript guide .

Install the plugin

To install the Speed Selection plugin, load it next to the core player:

Configure the plugin

The plugin can be set up at the top-level configuration under the speed namespace. Configuration properties are outlined in the following table.

Property	Description
`options` array	Sets up an array of speed factors where 1 is normal speed. If you don't specify anything in the configuration, the default `[0.2, 0.5, 1, 2, 10]` options are used.
`labels` array	Sets up an array where speed labels can be customized. By default, `labels` indices match entries in the `options` array. If custom labels aren't configured, entries from the `options` array are used with a playback speed multiplier or `x`. For example, if `options` contains `[0.5, 1, 2]`, the labels would be `[0.5x, 1x, 2x]`.

Example

An example configuration for the Speed Selection plugin looks similar to this:

const player = flowplayer("#player", { 
  src  : "//edge.flowplayer.org/functional.m3u8",
  title: "Functional with speed menu",
  token: "[your-player-token]",
  speed: { 
    options: [0.5, 1, 2],
    labels: ["Slow", "Normal", "Fast"]
  }
});
