Can't run citra on Linux 14.04 (trusty)

Issue:
I downloaded both nightly and canary build at https://citra-emu.org/download/
When I try to open citra, citra-qt and citra-room in terminal, they all say

: error while loading shared libraries: libavformat.so.57: cannot open shared object file: No such file or directory

I ran “locate libavformat.so” and showed that I have libavformat.so.54

I also tried to find libavformat.so.57 online but I just can’t find one.

Please help me
