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...

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.

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 all:
I'd like to grab images from video (wmv format, a physical file stored
in the host or even a streaming video, e.g. mms://abc.com/test.wma).
Is there any solution that after I put the timecode into the the
module, the PHP can return to the image corresponding to the timecode.
How can I do this? Thanks

I use this code to capture a screen in a regular VB 2005 windows app.
It works great! I found the code in google. But when I create a windows
service it does not capture the screen. It only captures a blank
graphic. Does anyone know why it will not capture the current screen?
Is something not available when running as a service? Thanks!!!

Hi guys, what i'm trying to do is do frame processing with the
possibility of the app to not be in focus.What happens if the capture
window gets hidden is that no more frames are sent to the
callback...I've tried fyield to no avail.I'd greatly appreciate it if
someone could put me on the right path with this one.

Hello
I'm writing a video recorder that records input from an external device
I use multipule files capture, and every X minutes i stop the graph, set the output file name to another file and run the graph again.
All in all, seems to be working well, i get multipule video files for my capture.
HOWEVER - for each file, there seem to be extra frames !

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.
This is as boiled down as I can make it.
Here is my compilation command:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp

Let's talk about the concept of autonomous AI software engineers and no-code agents. These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own....
Now, this would greatly impact the work of software developers. The idea...
