You might have to install from source. To do this, you'll need yasm.
yum install yasm
then you'll want to wget the file here: https://ffmpeg.org/releases/ffmpeg-snapshot.tar.bz2
You can unzip it as such: tar -vxjf ./ffmpeg-snapshot.tar.bz2
then finally make it as described here: https://github.com/FFmpeg/FFmpeg/blob/master/INSTALL.md
Type ./configure to create the configuration. A list of configure options is printed by running configure --help.
configure can be launched from a directory different from the FFmpeg sources to build the objects out of tree. To do this, use an absolute path when launching configure, e.g. /ffmpegdir/ffmpeg/configure.
Then type make to build FFmpeg. GNU Make 3.81 or later is required.
Type make install to install all binaries and libraries you built.
Hope this helps!
This guy tired to support it.
