trouble viewing webcam with graphedit

[drewdaman]

Hello all,

I am a TOTAL newbie to DirectX/Show etc. I want to use it to stream a webcam so i can view it on a different machine.

I tried a very simple graph (just to view teh webcam for the moment). i read somewhere that all you need to do to be able to view your webcam is to insert a filter .. (the webcam one).. in my case, go to Graph->InsertFilters->Video Capture Sources->Logitech QuickCam Web. Then you right click on the Capture output pin and say "Render Pin". I did this and i am able to view something. but what i am able to view is terrible! There are "fuzzy lines" across the view window and you can't make anything out! If i wave my hand in front of the webcam, you can see something is moving, but you can't really tell what it is.

I was hoping someone could suggest what i could do to fix this problem. Because i also read somewhere that if my graph doesn't work, tehn there is no point even attempting to write code because that will not work either.

THe precise instructions i read to do what i just described:

"To render live video:
! From filter list, under “Video Capture Sources”, insert filter
for camera
! Right-click on capture pin and select “Render pin”
! Press “Play”"

(on slide 10).

I'm not sure if i need any other filters. I know very little about multimedia stuff.. and there are just so many filters i don't even know where to start trying to fix this!

Would really appreciate any input you guys could give me on this!
Thanks a lot!
Drew

normally if your right click on the video source or its output pin you can set its resolution and format.

its likely that it has a default format that your graphics card dosent like and you just need to set it.

u often have to set it before linking capture source to anything else
