GraphEdit Capture and Preview

Hi,

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)
