AVI -> animated gif

#############################

Problem

You have an AVI and you want to convert it to an animated GIF.

Solution

Step 1

mplayer  file.avi  -vo gif89a  -vop scale=100:100  -frames 240

Meaning: resize to 100 x 100 pixels; take the first 240 frames from the AVI.

If it works, stop here.

If there is something wrong with the GIF output, then:

mplayer file.avi -vo jpeg -vop scale=100:100 -frames 240

It'll produce 240 JPG files.

Step 2

mogrify -format gif *.jpg

Step 3

convert  -adjoin  -loop 0  -delay 5  *.gif  animation.gif

Meaning: infinite loop; leave 5/100 second delay between the images.

Note: mogrify and convert are part of the ImageMagick package.
