I recently installed OpenCV 2.4.2 in Ubuntu 12.04.
I have also installed ffmpeg 0.11, Latest snapshot of x264, v4l-0.8.8 (All are latest stable versions)
cmake -D WITH_QT=ON -D WITH_FFMPEG=ON -D WITH_OPENGL=ON -D WITH_TBB=ON -D BUILD_EXAMPLES=OFF WITH_V4L=ON ..
make
sudo make install
When I do cmake, I get this

Whenever I use VideoCapture in C++ or Python, I get

What's the problem here ?
