Description

Hello all,

We are a research group from the Ruhr Universitaet Bochum (Germany) and we use the
cv::VideoCapture class to grab from various firewire/ieee1394 cameras.

For our purpose, we need to identify the cameras on the bus and we want to adjust the
cameras to exactly the same values as on the last startup.

It would be nice if it were possible to introduce four additional properties for the
cv::VideoCapture class and add support for the firewire backend.

These properties are:
CV_CAP_PROP_ZOOM
CV_CAP_PROP_FOCUS
CV_CAP_PROP_GUID
CV_CAP_PROP_ISO_SPEED

We have already implemented these properties in our local copy of the OpenCV-2.3.1 trunk.
There are two files which had to be patched: cap_dc1394_v2.cpp and highgui_c.h. We can provide
two patch files for the changes made by us.

We would be pleased if these changes could be integrated into the official repository.

Best regards,
Georg Hartinger

Thank you for the report! New properties were added in r7382 but it is necessary to test them in a future.
