Hi Miklos,
Some more questions concerning the build error:
Which version of OpenCV do you use? Do you use the automatically
downloaded OpenCV, which should then be 2.3? Under Windows or Linux? We
recently had some problems with Ubuntu, but they should be fixed now.
These errors occur at the superbuild-level, right?
>Do I have to install some development packages to get it work?
libavcodec-deve is installed
You actually don’t need any additional packages.

Hi,
I turned on OpenCV at the superbuild level and I got the following error:

Do I have to install some development packages to get it work?
libavcodec-deve is installed.
