JWPlayer is an in-browser multimedia player made by Longtail Video. Islandora uses it to create viewers for objects using the Audio Solution Pack and Video Solution Pack, so that they can be streamed directly inside a user's browser instead of requiring them to download it to their own computers first.
To download the JWPlayer files you need to create an account by clicking "GET JWPLAYER FREE" button on page http://www.jwplayer.com/download. JWPlayer is free for non-commercial use. Once your free account is set up, log into your account to locate the download link on "Account Settings" page.
The Islandora JWPlayer Drupal module required for Islandora integration can be found at the Release Notes and Downloads page.

Check the Audio Solution Pack and Video Solution Pack pages' configuration sections for more information on how to integrate JWPlayer into Islandora.
