Animated gif to avi on linux

问题

Is there any way to convert an animated gif to a video format (e.g. .avi) on Linux?

I have already tried

ffmpeg -i thegif.gif thevideo.avi

but all I get is the first image of the video.

回答1:

I can suggest combination of imagemagick and ffmpeg

do this to extract each frame as png/jpeg

$magick> convert 'images.gif[0]' image.png

Do this to convert images to movie sequence

ffmpeg -f image2 -i image%d.jpg video.mpg

ffmpeg's gif input doesn't work too well. It's usually easier to unpack the gif frames with convert (from ImageMagick) and process these with ffmpeg:

convert some.gif some%05d.png  
ffmpeg -i some%05d.png some.avi  
rm some*.png

If you like to have a certain framerate as input because the resulting video is to fast or to slow

ffmpeg -r 'xx' -i some%05d.png some.avi  

where xx is the input framerate.

If you dont want temporary files, you can try mencoder:

mencoder myfile.gif -mf fps=25 -o myfile.avi -ovc lavc -lavcopts vcodec=mpeg4

回答5:

If you like to have a loop as output

ffmpeg -loop 1 -t x -i some%05d.png some.avi

where x is the time the video should run in seconds.
