How to Configure DirectShow

Save

DirectShow is an API (Application Programming Interface) used by multimedia software to encode or decode video and audio files, or to play back and capture. Multimedia software sometimes comes with its own codecs for encoding or decoding audio and video, and third-party codecs are also available. If you are having trouble playing back multimedia files, it may be caused by a conflict between multiple DirectShow codecs. Windows does not provide a tool for selecting DirectShow codecs, but a third-party tool can handle the process.

Change DirectShow Filters

  • Visit the link in the Resources section to download "Windows 7 Preferred Filter Tweaker." Choose a location for the downloaded file and double-click it to install the program.

  • Open the program by double-clicking its icon on the desktop. You will be presented with a list of the DirectShow filters currently installed.

  • Click the toggle button next to a DirectShow filter you wish to enable. Only one filter can be enabled for each entry.

  • Click "Apply" to save your changes and click "Exit" to exit the program.

Delete or Reset DirectShow Filters

  • Visit the link in the Resources section to download "DirectShow Filter Manager." Choose a location for the downloaded file and double-click it to install the program.

  • Open the program by double-clicking its icon on the desktop. You will be presented with a list of the DirectShow filters currently installed.

  • Click to highlight a filter you wish to remove and click the "Remove selected filter" button to remove it.

  • Click the "Troubleshooting" tab and click "Restore standard DirectX codecs" if you wish to reset to the standard codecs installed with Windows. This can often fix conflicting filters by resetting them.

Tips & Warnings

  • You can reset all filters using Preferred Filter Tweaker by setting all filters to "Microsoft."
