R-OpenCV updating

The R-OpenCV project is being updated again.

The Ubuntu version: 11.04
The OpenCV version for development: 2.3.1 (August 2011) http://opencv.willowgarage.com/wiki/
The ffmpeg version: git (gtt clone git://git.videolan.org/ffmpeg.git ffmpeg)
The R version for development: R-devel 2.15.0 (svn)

The OpenCV Installation: http://opencv.willowgarage.com/wiki/InstallGuide. On my ubuntu, I had to install libasound2-dev and libjack-dev, otherwise the compilation raise errors.

Potential Problem & solution:
  • Use –enable-shared –enable-nonfree --enable-pic pic when configuring ffmpeg in case error happens during compiling of libopencv_highgui.so, moaning about the symbol av_destruct_packet.
