The location can be either an absolute address such as <CODE>http://xena/demo/media/Sample1.mov</CODE> or an address relative to the codebase address such as <CODE>media/Sample1.mov</CODE> <li>name: The name of this <CODE>MediaPlayer</CODE>. <li>size and position: The size and position of this <CODE>MediaPlayer</CODE>. <li>volume: The audio volume as a number from 0 to 5, where 0 is muted and 5 is the loudest possible volume. The default value is 3. <li>show control panel: Indicates whether or not the video control panel is displayed. <li>show caching control: Indicates whether or not the caching control is displayed. The caching control shows the download progress. <li>fixed aspect ratio: Indicates whether or not the aspect ratio of the video is maintained when the visual component is resized. </ul> <p> Two additional properties can be set. These are not bean properties, but provide additional control over the presentation: <ul> <li>ZoomLevel: Can be set through the popup menu and via set and get methods. (Click the right mouse button over the media to bring up the popup menu.) <li>MediaLocationVisible: Can be set through get and set methods. The media location is not editable during runtime. <h3>Invoking <CODE>MediaPlayer</CODE></h3> <p> You can instantiate MediaPlayer directly or using a bean-enabled IDE tool such as NetObjects BeanBuilder. To instantiate <CODE>MediaPlayer</CODE> directly: <pre> ClassLoader cl = this.getClass().getClassLoader(); MediaPlayer pb = (MediaPlayer)Beans.instantiate(cl, "javax.media.bean.playerbean.MediaPlayer"); </pre><P><DL><DT><B>See Also: </B><DD><A HREF="../../../../serialized-form.html#javax.media.bean.playerbean.MediaPlayer">Serialized Form</A></DL><HR><P><!--
