DeviceIOControl
|
From: OGLES on 21 Jul 2006 11:01 Hi all, I have the output from DeviceIOControl when trying to take a picture using a camera; something like this: if (DeviceIoControl(Camera_FileHandle, IOCTL_OEM_CAM_CAPTURE, &vinFrame, sizeof(VINFRAMEINFO), Camera_CaptureYUV2, CAMERA_CAPTURE_SIZEBYTES, &cbRet, NULL)) return true; } I can also dump the output as a file, but how can I convert this into a picture ? Thanks in advance, OGLES
From: Juggs Ravalia (MS) on 23 Jul 2006 00:13 It seems that you are using a custom OEM defined IOCTL here. Since the Camera driver could be written/changed by the OEM to provide more info - I would say that you contact the device manufacturer for more detials on the capabilities of IOCTL_OEM_CAM_CAPTURE IOCTL code.

From: OGLES on 13 Aug 2006 06:32 Hi Juggs, Unfortunately, it is not possible to contact the "device manufacturer for more details".. Anyhow - I've figured out that the output is RGB565, y-flipped.. so just now need to know how convert this into a Bitmap.. Any ideas ?
