Thanks Bplex
Well after a long run i got a solution

This error means your ffmpeg-php rpm is corrupted so i have just uninstall the previous all rpms of ffmpeg-php.

step 1
see how many rpms are there for ffmpeg-php on you system by this comand
rpm -qa | grep php

then uninstall the only ones having php-ffmpeg one by one

rpm -e php-ffmpeg-0.5.1-2.fc8.remi –nodeps

then WGET new one from here

http://rpm.pbone.net/index.php3/stat/4/ ... 6.rpm.html

rpm -ivh ffmpeg-php-0.5.1-1.fc7.remi.i386.rpm

install it and it will work fine
