What does this OpenCV installation error mean and how can I resolve it?

My system is Ubuntu 14.04. I tried many several methods to install OpenCV (tried both 2 and 3). I can not successfully install.

I followed [this documentation][1] for the installation and got this error.

UPDATE:

I reinstalled ffmpeg and x264. I have tried almost all the blogposts and official docs. This is the error I find:

UPDATE 2:

Please find the new error again here

UPDATE 3:

I upgraded to Ubuntu 16.04 and tried to reinstall OpenCV but it did not help. Find the error here:

/usr/bin/ld: cannot find -lSDL2 collect2: error: ld returned 1 exit status modules/videoio/CMakeFiles/opencv_videoio.dir/build.make:256: recipe for target 'lib/libopencv_videoio.so.3.1.0' failed make[2]: * [lib/libopencv_videoio.so.3.1.0] Error 1 CMakeFiles/Makefile2:6364: recipe for target 'modules/videoio/CMakeFiles/opencv_videoio.dir/all' failed make[1]: * [modules/videoio/CMakeFiles/opencv_videoio.dir/all] Error 2 Makefile:160: recipe for target 'all' failed make: *** [all] Error 2

libavcodec-dev was discontinued since trusty (14.04), and FFmpeg replaced it. Having said that, building opencv from source still requires this and some other deprecated libraries. (You might need to search in other repositories, look only for official ones). I noticed this error when I followed the same method of building opencv from source on Linux Mint 19 and Ubuntu 18.04 Gnome. You might also want to re-clone/download the opencv repository from GitHub and git checkout 3.4.1 or higher.

There were some dependencies which did not allow the system to install. I followed almost all tutorials. I could easily install OpenCV2/3 with conda.
