View Full Version : Grabbing frame without output on the screen

June 20, 2002, 18:38:39
I'm programing in VC++ and i'm trying to grab images from DFG/1394-1 converter and not to output them on the screen right away but rather modify them in some way and then dump on the screen. But when i make a call to Grabber::startLive() a window with the live feed is being created. Can you please outline the steps i need to take to avoid that?
Right now i do the following:
1.Initialize the library
2.Instanciate grabber
3.Create FrameGrabberSink
4.Set color format for the grabber
5.Get MemBufferCollection with newMemBufferCollection and then use it to setActiveMemBufferCollection
6.Make a call to starLive()
That's where the window with live feed pops up. I want to get rid of it.
7.Grab frames by calling getActiveMemBuffer()

Thank you for your time,

Hello Eugene,

you must call startLive() with the parameter "FALSE" to avoid a live display window.
