Description

We get a memory leak near 4 kbytes each 10-15 seconds while using elementary highgui functions like cvQueryFrame(). The leak can start either immediatly or in 2-3 minutes after launch. This error occures also in example application "cam-histo.py" and others. Minimal code that causes the leak seems to be:

import highgui
capture = highgui.cvCreateCameraCapture (0)
while 1:
    frame = highgui.cvQueryFrame (capture)

Environment: OpenCV 2.0.0.a, Python 2.6, SWIG python bindings, Windows Vista Home Premium.

Thanks, we know that in the new python bindings there is no leak problem. But there are some another problems, that make us to combine the old and the new bindings in one program.

swig python bindings are not included into OpenCV anymore. Let's make the new bindings good enough for all purposes.
