Ffmpeg error in linux

Question

Any help on how I can solve this error: ffmpeg: error while loading shared libraries: libavdevice.so.52: cannot open shared object file: No such file or directory

Solution

Basically, to find the file:

sudo find / -name libavdevice.so.52

For example, you've found this file in the /usr/local/lib. Next include that library into your library path. Add this to your /etc/ld.so.conf:

/usr/local/lib

And finally after modifying this file run this:

sudo ldconfig
