frank10 Posted February 11, 2012 Share Posted February 11, 2012 I have a Logitech C910 webcam that's capable of 1920x1080p pics. I want to make a window preview of 1280x720 or more. I used some DllCall to avicap and user32, like this: #include <WindowsConstants.au3> #include <GUIConstants.au3> global $gui, $cap, $avi,$user $avi = DllOpen("avicap32.dll") $user = DllOpen("user32.dll") $WM_CAP_START = 0x400 $WM_CAP_DRIVER_CONNECT = $WM_CAP_START + 10 $gui = GUICreate("test",1280,720,100,10) $cap = DllCall($avi, "int", "capCreateCaptureWindow", "str", "test", "int", BitOR($WS_CHILD,$WS_VISIBLE), _ "int", 0, "int", 0, "int", 1280, "int", 720, "hwnd", $gui, "int", 1) DllCall($user, "int", "SendMessage", "hWnd", $cap[0], "int", $WM_CAP_DRIVER_CONNECT, "int", 0 , "int", 0) GUISetState(@SW_SHOW) The result is a GUI window of 1280x720 with a webcam frame of 640x480. If I set 320x240 it gives a correct little pic, but it doesn't set it at a larger pic of 640x480. How can I display a webcam pic of 1280x720 or more? Is this a limit of avicap?

frank10 Posted February 12, 2012 Author Share Posted February 12, 2012 Should it be possible to display the webcam in a window with GDI+ or Direct2D ? Maybe this should reach the larger resolution. Has someone an example code? Link to comment Share on other sites More sharing options...

frank10 Posted February 12, 2012 Author Share Posted February 12, 2012 (edited) Yes, it has the same DllCall I posted above: doesn't work. Here I simplified more without the scale and preview, but those don't affect the resolution thing. Edit: apart the scale command that fills the window but it fills scaling the res, instead I want the original resolution larger than 640 without scaling.
