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].

Need to do[4]:
If you get this message: libv4l2.so.0: error adding symbols: DSO missing from command line collect2, do that:
If not works, start again using [5].
