GraphEdit Capture and Preview
April 24, 2007 at 5:05 pm | In GraphEdit | Leave a CommentHi,
It is actually possible to capture and preview transform filters with GraphEdit. This is really easy (I was so happy because I am a real newbie).
Steps to follow:
1.- Insert your capture device (webcam or other) . Graph->Insert Filters ->Video Capture Sources-> (Choose what you want, e.g. Logitech QuickCam Ultra Vision).
2.- Insert your Transform Filter (make sure that it is registered)
3.- Connect them by cliking right on the video capture filter pin. Select “Render pin” and GraphEdit makes all the work for you.
4.- Delete the Video Renderer (because we will split the output of your filter) .
5.- Insert the DirectShow filter called Smart Tee. Connect your transform filter with it.
6.- Insert the AVI Mux Filter (DirectShow folder) and connect its input with the output pin (capture) of the Smart Tee filter.
7.- Insert the DirectShow filter called File writer (give a name to it when it asked for) . Connect it to the AVI Mux filter
8.- Insert the Video Renderer (click right on the output pin of the Smart Tee and select the option “Render Pin”).
And That’s it !!!
You will save the output to an AVI file while you see a preview
PS: You can download GraphEdit from this site (you do not need to download Platform SDK to get this application)

cxcore100d.dll or cxcore100.dll not found

Well, check if you have correctly installed openCV :
http://opencvlibrary.sourceforge.net/VisualC%2B%2B
Do not forget to put the CV headers after the Visual Studio ones (sounds stupid but it was my problem). However, be careful because if you are using different versions of OpenCV, then this is clearly NOT a solution. In this case I would suggest to use OpenCV static libraries.
See you!
Marcelo
PS: Otherwise, use the brute force approach : copy all the openCV dll to the project directory…. (try not to do it)
DirectShow and OpenCV (Transform Filter)

There are some sources that might be useful for newbies like me.
An old guide version of DirectShow and OpenCV

DirectShow Wizard
April 19, 2007 at 8:46 pm | In DirectShow | 2 CommentsHaving trouble with the DirectShow wizard for visual c++ 6.0 when you
are using visual studio 8 ?
Well try the following link for the “new Wizard” :
http://tmhare.mvps.org/downloads.htm
Now, it may happen to you, too, that this doesn’t work because your this
version has been done for visual studio 7. In this case, you should
change the file DSWizard.vsz
I have something like this
VSWIZARD 7.0
Wizard=VsWizard.VsWizardEngine.8.0
Param=”WIZARD_NAME = DSWizard”
Param=”RELATIVE_PATH = VCWizards”
Param=”WIZARD_UI = TRUE”
You may need to change the relative path to something else (or using the
ABSOLUTE_PATH for the correct address) .
It worked for me, at least for now. Verify that your ‘DSWizard’ folder is in ‘C:\Program Files\Microsoft Visual Studio 8\VC\VCWizards’ and that your files. vsz .ico and .vsdir soient dans ‘C:\Program Files\Microsoft Visual Studio 8\VC\vcprojects’.
I do not know if you can start this wizard in your templates. If you have some information about it, please make a comment.
I hope this helps.
Marcelo
