GraphStudio

GraphStudio is an open source alternative/replacement for GraphEdit. The main reasons for this project were lot of cool features missing in GraphEdit tool. And of course, the fact that it’s not being developed as fast as one may need.

Features:

• Detailed System, Filter, Pin, MediaType information
• Reports
• Registry modification (add/remove types for filters manually)
• Information on registered filters (CLSID, name, file, version, location …)
• Detection of broken registry entries
• Easier graph construction
• Support for DVB, DVD, Capture graphs
• Inspection of media type formats including header parsing for existing codecs such as H.264, MPEG-2 …
• Dumping of media type formats for later analysis
• and many more ...

If you receive a "xmlLite.dll not found" error, you need to ensure this update for Windows XP has been installed.
