I've got this command working on two other servers.

ffmpeg -i in.flv -vhook '/usr/lib/vhook/imlib2.so -i vid_footer.jpg' 

of course the img is in the same directory I"m running it from. and the 
files are there however this is what I get.

[root at web1 videos]# ffmpeg -y -i in.flv -s 320x240 -t 00:00:51 -vhook 
'/usr/lib/vhook/imlib2.so -i vid_footer.jpg' out.mpeg

Seems stream 0 codec frame rate differs from container frame rate: 
1000.00 (1000/1) -> 29.97 (30000/1001)

Couldn't load image 'vid_footer.jpg'
Failed to Configure /usr/lib/vhook/imlib2.so
Failed to add video hook function: /usr/lib/vhook/imlib2.so -i 

I've tried moving the image and fully qualifying the path as well 
without any luck. I get the same thing when I do a -F verdana.ttf rather 
then an image load. As I said this exact same thing works on two other 
servers running the same OS just fine. I did the install using Yum with 
the DAG repo and it said everything was installed correct. The 
drawtext.so and watermark.so work fine. Any suggestions would be a 
greatly appreciated.
