[FFmpeg-devel] vhook, watermark and padding

I downloaded imlib2 v1.4.0 and finally got it installed. But I can't  
get ffmpeg to detect that it exists. I can't seem to find a devel  
package for this version. When I tried installing an RPM for an older  
version it still didn't pick it up.

Any idea how to make this work?
