QT Decompressor Filter

  • Article

[The feature associated with this page, DirectShow, is a legacy feature. It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation. Those features have been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use MediaPlayer, IMFMediaEngine and Audio/Video Capture in Media Foundation instead of DirectShow, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]

This component has been removed from Windows Vista and later operating systems. It is available for use in the Microsoft Windows 2000, Windows XP, and Windows Server 2003 operating systems.

The QT Decompressor filter decompresses Apple® QuickTime® 2.0 video. This format is typically used in older QuickTime files.
