[FIXED] Why python can't find libavcodec.so.54 after Ubuntu update from 14.10 to 16.04?

Issue

I've update from Ubuntu 14.10 to 16.04 yesterday and right now I've tried to run my old python + opencv files but every file with opencv gives the same error:

python blendImages.py 
Traceback (most recent call last):
  File "blendImages.py", line 2, in <module>
    import cv2
ImportError: libavcodec.so.54: cannot open shared object file: No such file or directory

you know some workaround this?

Solution

I think it may help if you install these packages.

sudo apt-get install libavcodec-dev libavformat-dev libswscale-dev libv4l-dev
sudo apt-get install libxvidcore-dev libx264-dev

and FFmpeg as well.
