DirectShow Detective is a straightforward software that reveals the version and file location of every DirectShow filter, audio compressor, and video compressor running on your computer.

The downside is that sometimes these third-party software components can completely mess up DirectShow, making it challenging for both users and vendors to troubleshoot the problem. Certain "codec packs" are known culprits for causing these issues.
Enter DirectShow Detective, a simple software that enables power users and tech support departments of video and audio software vendors to easily display the version and file path of each DirectShow filter, video compressor, and audio compressor on their system. This information helps identify whether a standard filter or codec has been installed or removed incorrectly.
Best of all, DirectShow Detective is completely free and compatible with Windows Vista. Say goodbye to the frustration of DirectShow errors and hello to smooth video and audio playback.
