Member Function Documentation

int avcap::QT_DeviceEnumerator::findDevices

(

DeviceCollector::DeviceList &

dev_list

)

Use this method to populate a DeviceList with the descriptors of the Devices found on the system.

Parameters:

dev_list

: the list that is filled with DeviceDescriptor-objects.

Returns:

0 on success, -1 else

virtual int avcap::QT_DeviceEnumerator::open

(

)

[virtual]

Open the underlying device.

The CaptureDevice-Object returned by getDevice(), which is actually used to perform capturing is not valid before open() is called.

Returns:

0 success, -1 on failure, e.g. open() has been already called before

Reimplemented from avcap::QT_DeviceDescriptor.

virtual int avcap::QT_DeviceEnumerator::close

(

)

[virtual]

Close the underlying device.

The CaptureDevice-Object returned by getDevice(), which is actually used to perform capturing, is not valid after close() is called.

Returns:

0 success, -1 failure

Reimplemented from avcap::QT_DeviceDescriptor.
