OpenCV 2.4.x over Ubuntu

I installed Opencv 2.4.8 over ubuntu 12.04, works good with images, but i getting error at display/read videos, then i research and use other resources:

[1], is best for me, have scripts for install opencv library, if you like more details about steps, is possible use [2] or [3].


-----------------------------------------

When you like java libraries
Need to do[4]:

$ export JAVA_HOME=/root/jdk1.7.0_07
$ mkdir build
$ cd build
$ cmake -DBUILD_SHARED_LIBS=OFF ../


If you get this message: libv4l2.so.0: error adding symbols: DSO missing from command line collect2, do that:

$grep -rl -- -lv4l1 samples/* modules/* | xargs sed -i 's/-lv4l1/-lv4l1 -lv4l2/g'

If not works, start again using [5].
