We can enable/disable decklink-LastFrameShown option by BlackmagicDesktopVideoUtility.exe ,But I need to change that programmatically.
I did not see anything about it in decklink SDK.
Please tell me where are saved BlackMagic-Decklink video card settings? (maybe in a file or registry but I can't find it)
OS = Windows 8.1 ,BlackmagicDesktopVideoUtility version=10.5
Thanks. (Sorry for my English)
I found that Decklink-LastFrameShownvideo (and other video card settings) saved in registry : HKLM\SYSTEM\ControlSet001\Services\DeckLink\Settings\1D482621\IdleVideoOutputOperation Value= Black/LastFrame
But when I change it manually not affect.
