 Summary of the bug:
 Hi all,
 I want to make video like http://113.171.224.242/videoplayer/output-
 1dd3aacc-010a-4303-8c53-919bb2e956a7.mp4
 This is my command. But it only zoom 1 corner

 How to reproduce:
 {{{
 ffmpeg -i 2.jpg -vf
 "zoompan=z='if(lte(zoom,1.0),1.5,max(1.001,zoom-0.0015))':d=125:x='if(gte(zoom,2.5),x,x+1/a)':y='if(gte(zoom,2.5),y,y+1)'"
 -c:v libx264 -t 10 -s "3872x2592" zoomout2.mp4
 }}}
 Patches should be submitted to the ffmpeg-devel mailing list and not this
 bug tracker.
