CentOS Error: "cannot restore segment prot after reloc: Permission denied"

I'm trying to convert an AVI to FLV using. I installed ffmpeg using:

yum install ffmpeg

NOTE: It would be better if you also install some important decoders and encoders for converting.
This tutorial might help you on how to completely install your ffmpeg.

After installation I run ffmpeg but I was blocked by this error:

ffmpeg: error while loading shared libraries: /usr/local/lib/libx264.so.68:
cannot restore segment prot after reloc: Permission denied

To solve this simply type the following:

/usr/sbin/setenforce 0

Afterwards, I continue with converting using this code:

ffmpeg -i input.avi -sameq -ar 44100 output.flv

wherein the input.avi is the raw avi file and the output.flv is the result FLV converted file.

If you did the things above correctly, your AVI should now be an FLV!
