Ok, i've tried with this commandline:

./ffmpeg -i 
/home/guillaume/Desktop/guillaume/The_Godfather-1972_snow.avi -vhook 
/home/guillaume/Prgm/ffmpeg/vhook/watermark.so -f ~/Documents/7.15.gif

I guess I'm missing smth. I don't use the commanline tool "ffmpeg" so 
I'm  not familiar with its commandline. Maybe it doesn't work because I 
missed smth.
