Hi, Co.De. said:

hi,

i would like to resize video and overlay with image. when i resize video, e.g. from 624x352 to 320x240, and use imlib2 vhook in one line, i get 320x240 video with small picture in the corner: ffmpeg -i infile.avi -cropright 52 -cropleft 52 -s 320x240 -aspect 1.333 -vhook './imlib2.so -x 0 -y 0 -i image.png' outfile.avi

i know that options for imlib2 are -x -y for coordinates, and i would like to know how to use """ Expressions are functions of these variables: N frame number (starting at zero) H frame height W frame width h image height w image width X previous x coordinate of text or image Y previous y coordinate of text or image """ precisely, how do i tell to the image to keep the same size ? do i have to use two commands ? like in first command resize video, and in second use vhook ?

Right, either you use two commands or you compile libavfilter (http://wiki.multimedia.cx/index.php?title=Libavfilter) and then you may use one command: ffmpeg -i infile.avi \ -vfilters crop=52:0:-1:-1,scale=320:240 \ -aspect 1.333 \ -vhook './imlib2.so -x 0 -y 0 -i image.png' outfile.avi Regards, V?ctor
