Hi,
I am using QTKit APIs for streaming from webcam. I get the error
message 'Camera used by another application' for some of the webcams.
But, no other application was using this webcam. The applications like
Photobooth, iChat can stream properly from this webcam
Following are the steps to stream from the device:
1. Open the input device: [inputDevice open: &error]
It opens the device successfully without any error.
2. add input device to capture session: [captureSession addInput:
inputDevice error: &error]
3. Call [captureSession startRunning]
But, it displays a message 'Camera used by another application' in
QTCaptureView( We are not sure whether it is put up by QTkit framework
or the webcam driver). We also get the following console log:
"usbConnectToCam-USBDeviceOpen: Error: kIOReturnExclusiveAccess -
exclusive access and device already open"
Can anyone help me out to solve this problem.
Thanks in advance,
Deepa
