Use ffmpeg to resize image

Question

Is it possible to resize an image using FFMPEG?

I have this so far:

ffmpeg. -i 1.jpg -vf scale=360:240 > 2.jpg

I get the error messa

Answer 1

If you want to retain aspect ratio you can do -

./ffmpeg -i 1.jpg -vf scale="360:-1" 2.jpg

or if you want to resize based on input width and height, let's say half of input width and height you can do -

./ffmpeg -i 1.jpg -vf scale="iw/1:ih/2" 2.jpg

where

iw: input width
ih: input height
