Audiodescription plugin

This plugin plays a closed audiodescription parallel to the main file, for accessibility or director's comments use. This audiodescription is a single MP3 file.

This plugin is compatible with version 4.1 of the player. For 4.3+, the plugin will place a button in the controlbar. For 4.5+, the plugin can also place a button in the dock (if the dock=true flashvar is set).

Example

Here is an example of the audiodescription plugin in action. Below is the string of flashvars used. The female voice represents the AD:

Get the Flash Player to see this player.

file=/player/testing/files/corrie.flv&plugins=audiodescription&audiodescription.file=/player/testing/files/corrie.mp3

Configuration

The plugin is loaded with the flashvar plugins=audiodescription. This will automatically load the latest version of the plugin straight off our servers. It offers three additional flashvars for tweaking the plugin:

  • audiodescription.file (undefined): location of the audiodescription MP3 to play.
  • audiodescription.state (true): set this to false to turn off the audiodescription by default.
  • audiodescription.volume (90): volume of the audiodescription. Crank this even more up to have the AD overrule the default sound. We're still working on an update of this plugin that will automatically duck the original audio when there's a significant volume on the audiodescription.

Note that MP3 files should preferably be in a 44.1Khz, constant bit rate format. Flash fails to play back MP3 files in various other formats, resulting in either chipmunk effects or suddens stops halfway the file.
