Hi Miklos,
sorry I missed you message. OpenCV has some trouble with certain FFMPEG
versions (Google will give you the best links ;) ). The superbuild currently
uses OpenCV 2.3 which should be used with the latest FFMPEG version. Thus,
either you update your FFMPEG version or you turn it off for OpenCV: Open CMake
in the OpenCV-Build directory and turn off "WITH_FFMPEG", reconfigure and
compile again.
Regards,
Michael

Betreff: Re: [mitk-users] OpenCV build error
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.
