Video Capture Programming

I have a couple of different video capture boards, a Miro
DC50 and a Snazzi.  Both support Direct-X.  I would like
VB sample for capturing video from either of these devices.  

I would like to be able to capture still images in jpg or gif format or movies in AVI or other formats.  I'd be happy to give 100 points to someone who points me to a resource that solves my problem, or I can up the points for a workable code sample.  Please don't suggest that I shell out to the video capture software that comes with the cards.  I know I can do that, but would prefer to develop a application overwhich I have more control.  Thanks!

(Hint, I think there may be such a sample in the DirectShow SDK but I don't have access to this)

Hi mdougan,

Why don't you have acces to the DirectShow SDK, if you have an internet connection you can download it. And even if you can't download it you can look into at the MSDN site because it's free and you only have to register once.....:O)

Look at these links
http://premium.microsoft.com/msdn/library/sdkdoc/bpc/vidrf_3bxw.htm

http://premium.microsoft.com/msdn/library/backgrnd/html/msdn_dx5media.htm

this one contains a great layout of DirectShow and the object model

looking into the future?

OKidOKi think this will do it......
I'm not a real fan of MS but as a Windows developer I must say they really try to help us out leveraging their investments.
:O))
Good luck!

Thanks for responding.  It was the only response I got.  I followed each link and they never led me to the exact info I needed.  One was for Windows 98, and I only have Windows 95 or Windows NT, the site for downloading the SDK says that it is no-longer available for downloading, but that I can order the SDK on disk.

I was hoping for some sample code that could keep me from installing the whole SDK, but it doesn't look like I'm going to find the answer I was hoping for.

I did find a company that sells an Active-X control for doing what I want, through one of the links, but it is a bit pricey, and the demo didn't work with my capture cards... so...

I've decreased the points to 50, since you've helped, but still have not  given me a resource to solve my problem.

Oh, I guess they don't let you lower the points, so, OK, you did go to a lot of trouble to track down the links!

Hmmmm......
You are looking for a VB sample for capturing video (AVI) or images (JPEG or something)? I will be looking for it, OK? since I didn't come up with a solution but with an answer.
:O)

Yes!  But most things I've run across, talk about making calls to the Video For Windows API, so, I may need the SDK regardless - as there might be some DLLs there that I need.  I do believe that the Video For Windows SDK has some VB examples.

Thanks!

I just found an answer to another question on video capture that included a helpful link.

Go to Shrinkwrap Visual Basic.  This is a great resource for Directx sample and Vidcap.  Area 51 is another place to land.
