FIX: Content plays longer than the time that is specified by the duration element in a Windows Media Player 11 playlist for content that is 30 minutes or more

View products that this article applies to.

SYMPTOMS

Consider the following scenario:

In Microsoft Windows Media Player 11, you use a metafile playlist to stream audio or video content. For example, you use an ASX file.
The length of the content is 30 minutes or more.
The playlist contains a duration element for the content that you are playing.

In this scenario, the content plays longer than the time that is specified by the duration element in the playlist.

Back to the top

This issue occurs because Windows Media Player uses approximate seeking when it plays back certain types of content that are longer than 30 minutes. When Windows Media Player uses approximate seeking, the underlying framework ignores the set duration element.

For more information about approximate seeking, see the Windows Media Format SDK.

MORE INFORMATION

Steps to reproduce the behavior

Create Windows Media content that is longer than 30 minutes.
Put the content on a Microsoft Windows Media 9 Series server.
Create an ASX file that points to the content on the Windows Media 9 Series server and uses the duration element to play the content for a limited time. For example, the ASX may resemble the following code example.
<ASX version = "3.0"> <Entry> <Ref href = "mms://mediaserver/video.wmv" /> <DURATION VALUE="00:00:30" /> </Entry> </ASX>
In Windows Media Player, open the ASX file to play the content.
