Float-on-Scroll plugin

This plugin provides float-on-scroll functionality for Wowza Flowplayer. When a user scrolls past the main player on a page, the default behavior forces the player container to pop out to a fixed position. Media playback continues in the floating, popped-out container. If the user scrolls back to the main player, the floating container disappears, and playback resumes in the main player element.

Info

The Float-on-Scroll plugin does not work inside an <iframe> element.

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

You can load the Float-on-Scroll plugin next to the core player and any other plugins you would like to use:

Configure the plugin

There are no mandatory configuration options for the Float-on-Scroll plugin. You can just load the plugin to activate it. The following properties allow you to manage the default behavior for the Float-on-Scroll plugin.

Property	Description
`float_on_scroll` boolean	Default value is `true`. When `false`, disables the Float-on-Scroll feature for selected players.
`float_default` boolean	Default value is `true`. When `false`, disables the default behavior for the Float-on-Scroll plugin. By default, the player container pops out to a fixed position on the page when a user scrolls past the main player container. The fixed container pops back in when the user scrolls past the main player position.

Info

When using multiplay, the Float-on-Scroll feature is automatically disabled to prevent UI inconsistencies caused by multiple players floating at the same time. Optionally, you can disable the plugin for selected players.

As an example, use the following code snippets when implementing and working with the Float-on-Scroll plugin.

      token: "[my-player-token]",
      float_on_scroll: true
  });
</script>

Listen to plugin events

This section describes the events you can capture to control and manage the floating behavior of the player. To understand event handling differences between CDN or npm implementations, see Plugin events.

CDN event	npm event	Description
`flowplayer.float_on_scroll.events.EXT_BTN_CLICK`	`FloatOnScroll.events.EXT_BTN_CLICK`	Emitted when a user clicks to exit the floating player. By default when exiting the, when a user clicks to exit the floating player, the floating container pops back in and media playback is paused in the main player container.
`flowplayer.float_on_scroll.events.POP_OUT`	`FloatOnScroll.events.POP_OUT`	Emitted when the player pops out from the main player container to a fixed position on the page.
`flowplayer.float_on_scroll.events.POP_IN`	`FloatOnScroll.events.POP_IN`	Emitted when the player pops back in from a fixed position to the main player container on the page.

Example

The following example sets up an event listener to capture when the player pops back in from a fixed position to the main player container on the page.

CDN examplenpm example

Copy

Copied

player.on(flowplayer.float_on_scroll.events.POP_IN, () => console.log("Player popped in!"))

Copy

Copied

player.on(FloatOnScroll.events.POP_IN, () => console.log("Player popped in!"))

Control floating behavior

The methods described in this section allow you to trigger and control the floating behavior of the player.

Method	Description
`popIn()`	Use to revert the player from its fixed, popped-out position and into the main player on the page.
`popOut()`	Use to pop out the player from the main player position to a fixed, popped-out state.

Advanced usage

Configure multiple players

If you plan on using the Float-on-Scroll plugin with multiple players on a page, you must specify which player should float. Only one of the players in this scenario can have the float_on_scroll property set to true. When this preference isn't explicitly set, the first initialized player floats by default. For an example, see this sample configuration:

Copy

Copied

const player1 = flowplayer("#player_1", { 
  src: "videos.example.com/your_content.m3u8",
  float_on_scroll: false
})

const player2 = flowplayer("#player_2", {
  src: "videos.example.com/your_content.m3u8",
  float_on_scroll: true
})
