Using PARAM Elements in a Web Page Displayed by Firefox

[The feature associated with this page, Windows Media Player SDK, is a legacy feature. It has been superseded by MediaPlayer. MediaPlayer has been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use MediaPlayer instead of Windows Media Player SDK, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]

You can use PARAM elements inside an OBJECT element to set the initial state of the Player control. For example, the PARAM elements in the following example specify that the control should play seattle.wmv automatically.

<OBJECT id="Player" type="application/x-ms-wmp" width="300" height="200">
  <PARAM name="url" value="c:\MediaFiles\seattle.wmv" />
  <PARAM name="autostart" value="true" />

Most PARAM elements can be interpreted by Internet Explorer and by Firefox. However, there are a few PARAM elements that the Firefox plug-in does not support. For information about which PARAM elements are supported by the Firefox plug-in, see PARAM Elements in an OBJECT Element.
