Video and screen capture: problem on win 7
I want to capture screen flow in video or image on windows 7 64 bits system, with NVidia Quadro 600 graphic card (driver is up to date). I use lib "VLC" for video capture, or "print screen" button for image capture.
When I try to capture a fullscreen opengl application, or a QML application, or WPF application, the captured image is black. It seems that graphic card content can't be acquired...
It is the same for each computer which is under windows 7.
This manipulation worked on windows XP.
what are the changes on screen capturing between windows XP and windows 7 ?
how can I resolve this problem ?
is there any option to activate in system ?
is there any software which could work (with an API) ?
Thank you very much,
