Hello,

Basically, followed this step.

http://docs.opencv.org/doc/tutorials/introduction/linux_install/linux_install.html

got source from git clone https://github.com/Itseez/opencv.git

I typed make and waited..but got error..

maybe you need to update/upgrade ffmpeg library via sudo apt-get

Different versions of FFMPEG are not binary or source compatible. OpenCV drops support of some ancient FFMPEG versions. I do not know minimal supported FFMPEG version, but recommend you to use something upper then 1.0. FFMPEG I'm sure that FFMPEG 1.0 is supported.
