Is /usr/local/lib
searched for shared libraries ? I have this error:
[Leo@chessman ~]$ whereis ffmpeg
ffmpeg: /usr/local/bin/ffmpeg
[Leo@chessman ~]$ ffmpeg
ffmpeg: error while loading shared libraries: libavcore.so.0: cannot open shared object file: No such file or directory

Make sure your LD_LIBRARY_PATH
is set up to include all directories you want to search and then test it again.
You can test this quickly with:
LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/lib ffmpeg
which will set it only for that invocation.
Alternatively, you can edit /etc/ld.so.conf
which contains the default directories searched. Some Linux distributions may not include /usr/local/lib
in that file.
Note that you may also need to update the cache /etc/ld.so.cache
by running ldconfig
(as root, or with sudo
).
