Dear all,
I've got a video capture device. Device manager shows "nVidia WDM Video
Capture (universal)" driver in "Sound, video and game controllers"
category. Also, Windows Movie Maker, and other standard video capture
tools can record video from the device.
But, I've got no idea how to read transmitted data in a C# application.
All I'm gonna do is to show the real-time movie on an appropriate
control on my form.
Any sort of help would be highly appreciated ;)
Best regards,

There is no direct way in C# or .NET to do so, however with some external
libraries you can. One well known and powerful method is DirectShow.NET
( http://www.codeproject.com/cs/media/directshownet.asp) which is a wrapper
around many DirectShow and unmanaged calls to DirectX.
Another easy method, is DirectX.Capture
( http://www.codeproject.com/cs/media/directxcapture.asp) which is a library
that wrapps itself around the previously mentioned DirectShow.NET and makes
capture very very easy.
Still another option, would be breaking out some Managed DirectX (found with
the DirectX 9 SDK) and manually hitting DirectShow on your own to do the
recording.
I should mention, by using DirectShow (via any of the above mentioned
mechanisms or any other for that matter) for your capturing, you save
yourself a lot of time and hassle in writing your own low level system to
communicate with the driver or video buffer.

Dear Brendan,
You can not imagine how helpful you have been :)
I've not yet studied the source code but the demo project is the right
thing that I needed.

Hi,
Im trying to develop a Visual C# .NET app. that uses DirectShow filters to capture video from camera source. However, after going through a series of articles, I've seen that DirectShow is not directly supported in Visual C#.NET.
Im wondering if there's any way to use the video-capture filters of DirectShow in Visual C#.
Otherwise, would it be possible to create a Visual C++ DLL that uses DirectShow filters to capture video from a WDM...

Hi,
Could anyone point me in the right direction for using video capture? I'd
like to write a basic VB.NET app that shows the output from a composite
camera and has a simple record now button. (I'd also like to be able to
control things like frame rate etc.)
At the moment my knowledge in this area is pretty basic so I'm just looking
for some online resources where I can gem up on the subject. For example if
I use a third party API,...

Hello.
I would like to preview video, capture still images and record video
simultaneously with my AGP capture card. I have to do it in dotNET. Is
there a dedicated solution to do that in dotNET? Or the only solution
is to write wrappers to access old directShow?
TIA for any answers

Hi,
I want to get a video capture card for my PC, which runs both WinXP Pro SP3 and Vista Business SP1.
Nearly all the video capture cards I see state they only run on Windows Media Centre Edition.
Is this strictly true? Is there some software I can put onto XP that will provide the same services as MCE?
Regards,
Rob.

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows.
