Hi, we are using the DFG/1394-1 on different machines (P4, 2GHz, Centrino 1,4GHz) with Radeon 9200 or Radeon 9700 Mobility. Until now i failed to use the hardware abilities of the graphics cards for scaling and deinterlacing (video overlay). Is this possible at all? Does IC Capture Standard output to the overlay? Can you tell us a sample graph for usage with graphedit which will demonstrate output to hardware overlay?

My fault, output to overlay works. But why are the controls on the graphics cards properties overlay page disabled? (helligkeit, ..., gamma)

Hello,

The properties are disabled, if they are not supported through the WDM driver of a device.

IC Capture does not output to the overlay.

If you want to use the overlay, you must insert the overlay video renderer into your filtergraph. This video renderer should be delivered with DirectX 9 . If i am right, it is named "video mixing renderer 9". But i never tested this.
