Those are files installed by libraries that are ffmpeg dependencies.

Here's a link that shows how to install ffmpeg on centos (as package):

Thank you for the post. I have the following libraries missing in my centos server. How to install them?

/usr/local/lib/libavdevice.so.52
/usr/local/lib/libavdevice.so.52.2.1
/usr/local/lib/libavfilter.so.1.38.1
/usr/local/lib/libavfilter.so.1
/usr/local/lib/libavcodec.so.52.87.0
/usr/local/lib/libavcore.so.0
/usr/local/lib/libavcore.so.0.6.0

Thanks.

Thank you for the post. Checking my Centos Server I notice some libraries that you mention in the post are missing. Those below:

/usr/local/lib/libavdevice.so.52
/usr/local/lib/libavdevice.so.52.2.1
/usr/local/lib/libavfilter.so.1.38.1
/usr/local/lib/libavfilter.so.1
/usr/local/lib/libavcodec.so.52.87.0
/usr/local/lib/libavcore.so.0
/usr/local/lib/libavcore.so.0.6.0


How to install those libraries?

Thank you for your help.

[b]ffmpeg: error while loading shared libraries: libavdevice.so.52: cannot open shared object file: No such file or directory[/b]

After installling ffmpeg on CentOS 4.8 the above error apears when running ffmpeg for the first time.
[code]# ffmpeg
ffmpeg: error while loading shared libraries: libavdevice.so.52: cannot open shared object file: No such file or directory[/code]
Running [i]ldd[/i] utility shows that ffmpeg binary is dynamically linked to libraries which cannot be found:
[code]# ldd `which ffmpeg`
libavdevice.so.52 => not found
libavfilter.so.1 => not found
libavformat.so.52 => not found
libavcodec.so.52 => not found
libswscale.so.0 => not found
libavcore.so.0 => not found
libavutil.so.50 => not found
libm.so.6 => /lib/libm.so.6 (0x006c3000)
libpthread.so.0 => /lib/libpthread.so.0 (0x007e9000)
libc.so.6 => /lib/libc.so.6 (0x00575000)
/lib/ld-linux.so.2 (0x00557000)
[/code]

All ffmpeg required libraries have been successfully installed under /usr/local/lib/ directory:
[code]# find /usr/local/lib/ | grep -E "libavdevice.so.52|libavfilter.so.1|libavcodec.so.52|libavcore.so.0"
/usr/local/lib/libavdevice.so.52
/usr/local/lib/libavdevice.so.52.2.1
/usr/local/lib/libavfilter.so.1.38.1
/usr/local/lib/libavfilter.so.1
/usr/local/lib/libavcodec.so.52.87.0
/usr/local/lib/libavcore.so.0
/usr/local/lib/libavcore.so.0.6.0
/usr/local/lib/libavcodec.so.52
[/code]

To make ffmpeg binary look in this directory for linked libraries, edit [i]/etc/ld.so.conf[/i] and add this path:
[code]
include ld.so.conf.d/*.conf
/usr/local/libevent-1.4.14b/lib
/usr/local/lib
[/code]
[code]# ldconfig[/code]

Now run ffmpeg again and it works:
