C# Capture image on webcam physical button press event using directshow

[red00dragon]

i am developing application to capture image from webcam using .net and directshow.

i want to capture image when the hardware button available on webcam is pressed.i cant be able to do it using directshow library.Is there any way in directshow to detect webcam hardware button press event so that i can capture image on that event and save it?

i am using the intraoral webcam used by dentists.

please provide complete code. i am really stuck with this issue.

any help regarding this is appreciatable.

thanks & regards

hi,

i guess you can only detect the press event, if you have some api of the driver of the device. If there isnt any public api it will be a hard job to get the event.

Another idea is, try to do remotecontroll of a standard software for the device (maybe amcap, or stuff like that)

greetings

Perhaps you can request some docs from the manufacturer of that cam. If you're lucky the manufacturer addionally send you the api/drivers to access the cam.
