When I want to run ffmpeg I get the following error:ffmpeg: error while loading shared libraries: libtheoraenc.so.1: cannot open shared object file: No such file or directoryThis is output of ls \usr\lib -l | grep libtheora:-rw-r--r--  1 root   root    419238 Jan  5  2010 libtheora.a-rw-r--r--  1 root   root       935 Jan  5  2010 libtheora.lalrwxrwxrwx  1 root   root        19 Jan  5  2010 libtheora.so -> libtheora.so.0.3.10-rw-r--r--  1 root   root    145636 Jan  5  2010 libtheoradec.a-rw-r--r--  1 root   root       948 Jan  5  2010 libtheoradec.lalrwxrwxrwx  1 root   root        21 Jan  5  2010 libtheoradec.so -> libtheoradec.so.1.1.4-rw-r--r--  1 root   root    334696 Jan  5  2010 libtheoraenc.a-rw-r--r--  1 root   root       954 Jan  5  2010 libtheoraenc.lalrwxrwxrwx  1 root   root        21 Jan  5  2010 libtheoraenc.so -> libtheoraenc.so.1.1.2What should I do to solve the problem?Edit: in line:libtheoraenc.so -> libtheoraenc.so.1.1.2I can't find libtheoraenc.so.1.1.2 in /usr/lib(packages libtheora and libtheora-dev are installed)output of locate libtheoraenc.so.1.1.2 is:/usr/lib/libtheoraenc.so.1/usr/lib/libtheoraenc.so.1.1.2But I can't find this files in /usr/lib!

I think I'd recommend a reinstall of libtheora0:sudo apt-get install --reinstall libtheora0And since you have some non-unixey backslashes in your original question, let's be explicit about looking for the libraries:ls -l /usr/lib/libtheoraenc*
