Abstract: In general, techniques are described of automatically configuring an embedded media player. For example, a user interface such as a web page or a user interface of a media player may include an embedded media file that is to be presented. In addition, the user interface may display an input mechanism that offers a user the opportunity to present a higher-quality version of the media file. When a client device receives the user interface and a user interacts with the input mechanism, a specialized media player is automatically downloaded to the client device. The specialized media player then automatically downloads a higher-quality version of the media file and begins playing the higher-quality version of the media file automatically. The specialized media player may obtain the higher-quality version of the media file using peer-to-peer or other download acceleration techniques.
