Desktop capture driver

Hello,

How I should write a desktop capture driver? Basically this driver
should work as a virtual video driver.

Is anybody point out me from where I should start with?

Note: I have already written a virtual video driver which is a user mode
DLL. Is this the way I should follow for the desktop capture driver?


Thank you,
Sreeram

Based on my (very) limited experience, I would suggest starting with the
mirror driver in the DDK.

Mirror driver is the solution.

You may look at the TightVNC open-source project:

hi sreeram.

how are you?


you can simply capture the desktop
1 5 or 30 times a second.
(as u see fit)

if this is not suiteable,
then tell us your system needs.

Thank you for all.

I need to write a virtual video driver( like a webcam driver --- but
here source is desktop and to capture all changes ) which should capture
the desktop continuously. This driver should show as a video source for
any video recording applications, like WME, Adobe Premiere etc...

If I write it as a mirror driver will it show as a "video source" for
video recording applications?

Thank you,
Sreeram

Develop the ancient-style VfW driver, it will be simplest, and DirectShow
will be emulated on top of it by QCAP.DLL.

Also - I know people in Russia who can sell you this module with sources,
the module is debugged and has the Win98 version.

Hello Maxim,

I know how to develop the VfW driver. I hope you must have been
remembering I posted tooo much questions at the time. But that driver
captures network streams. It is working fine.

But I would like to capture desktop here continuously (including
changes) instead of network streams. Could you please point out me
related article(capturing desktop continuously --- including desktop
changes) from where I can start? I will read and implement it myself.

Thank you,
Sreeram
