`no decode delegate for this image format`

[pixelastic]

Hello,

I just tried to use gifify to extract a gif from a mp4 video I downloaded from YouTube, and got the following error:

$ gifify input.mp4 -o output.gif --from 257 --to 279 --resize 250:-1
convert.im6: no decode delegate for this image format `/tmp/magick-Ij8cWq6S' @ error/constitute.c/ReadImage/544.
convert.im6: no images defined `gif:-' @ error/convert.c/ConvertImageCommand/3044.

I'm on Ubuntu, with the following dependency versions:

[vvo]

The video is available to download [here](http://tmp.pixelastic.com/Joachim de Posada - Ne mangez pas le marshmallow-553.mp4). It was originally downloaded with youtube-dl.

Edit: I just installed MP4Box, but I'm not sure exactly what command you would like me to run on my file.

I think your ffmpeg version is way too old.

Which version is the minimum?
