Hey Guys,
I had question regarding the cameras hardware trigger functionality. I am using the Snapshot Maker sample application and it is working great with the camera I am using but there seems to be no way to actually detect when the snapshot button on the camera is pressed. The event handler seems to fire only when the new frame is ready and not when the button is actually pressed. Is there a way to detect this snapshot button is pressed before it starts to render the new frame from the snapshot pin?
I would like to display a message to the user when the snapshot button trigger is recognized so that they know something is happening in the background (grabbing a new frame) when the video stream stops. Depending on the resolution of the snapshot frame it can take several seconds for the new frame to come in and it might appear the the application is frozen. If it's possible to trigger another event when the trigger button is actually pressed (and we are waiting for the snapshot frame) the user could be notified with a message or something.
Thank you for any help!
