Morning SO.
I would like to compile openCV to make it work on a webcam capture using Qt 4.7. For that purpose, OpenCV must be compiled for a 64bit system.
So, I've tried 3 compilations :
Compiling from the source with cmake :
sudo cmake -G "Unix Makefiles" .
it works, but I can't dump a video into a file using cvCreateVideoWriter : the output file is empty.
using macports :
sudo port install opencv
it's not that great because it depends on gtk2, ffmpeg and the libX .. and there is no image captured.
using the compiled framework
the framework is compiled for 32 bit system only.
Does anyone have an idea ?
