Capture Frame from camera in Windows

(1/3) > >>

Dzandaa:
 Hi everybody,

 Working with Lazarus Pascal 2.012 FPC 2.3.0 on Windows, Linux and MacOS

Is there a good solution to grab a frame from a camera in windows with examples.

In Linux I have the 5dpo Component Library TSdpoVideo4L2 that work fine and easy to grab a frame from a WebCam,
but I didn't found an equivalent for Windows where all solution depends of external programs like VLC or MPlay...

Thank you.

In windows you can use directshow for it.

Hi,

What library do I need?
I'm on Windows 64 Bits.

Do you have an example for Lazarus?

Thank you.

af0815:

Hi,

Thank you,

I also fond the DSPack library, but not a working example.

All I found was for Delphy and there are some missing Definition (or different)

I'll look at your link.

I'm converting one of my C# program to Pascal Lazarus (3D digitizer with a camera and 4 lasers)
On Linux, I have a library that can grab frames from a WebCam,
but I'm also looking for a similar Windows solution.
