FIX: It may take an exponentially long time to index long files in a custom application that was built by using the Windows Media Format 9.5 SDK (896097)


The information in this article applies to:

  • Microsoft Windows Media Format 9.5 SDK

SYMPTOMS

Consider the following scenario. You have a custom application that was built by using the Microsoft Windows Media Format 9.5 SDK. When the application indexes long files, you may notice that it may take an exponentially long time to complete the indexing process.

Note Typically, this issue occurs when the files that are being indexed are 90 minutes or longer.

CAUSE

This issue occurs because the data structure that is used for maintaining the list of indexes is inefficient for adding new index points.
