Welcome to Graphedit
Graphedit is an excellent program for using Direct Show Filters and apply them directly to your multimedia. It is provided by Microsoft in the platform SDK or in various other DirectShow filter packages. No third party program is needed. I use this program very often and is probably the only other Microsoft program other than Windows 2000 that I enjoy to use so much. I would recommend Graphedit to anyone who works with multimedia on a daily basis and/or wants to achieve high quality results. It may be frustrating for some to use, but if you take the time to learn how to use it, you won't be able to work without it. Now that I'm finished with my Graphedit promotion, let's get on with the tutorial =P
Before we begin using Graphedit, we need to make sure we have all the necessary filters installed . If you have any form of software DVD player, like PowerDVD, MPEG-2 filters we need will already have been installed with the PowerDVD installation. Basically, the filters we need to supply for Graphedit are:
- An MPEG-2 stream splitter (You can use Microsoft's or Ligos' splitter)
Microsoft's splitter only recognizes one audio channel
- An MPEG Audio Decoder (Comes with your software DVD player)
- An MPEG Video Decoder (Comes with your software DVD player)
- the WAV DEST filter (Comes with Graphedit)
If you have these filters, but they are not registered, simply place the files *.ax in a safe directory (eg. C:\Windows\System or C:\WINNT\System32), then register the filters by using the command prompt:
- regsvr32.exe (insert filtername).ax
You will need to know the location of regsvr32.exe if it is not in your path. Also, make sure you include the file's extension (ax) when registering it. If the filters aren't in the Window's System directory, you'll need to include the full path (no spaces). An example:
- regsvr32.exe C:\Documen~1\Admini~1\filters\(insert filtername).ax
To unregister any Direct Show Filter, just use the -u option with regsvr32.exe:
- regsvr32.exe -u C:\Documen~1\Admini~1\filters\(insert filtername).ax
