convert delegate for quicktime video

Post by martyl »

I wanted convert to make thumbnails of a quicktime video.

When I specify a quicktime video, convert complains about a
convert: no decode delegate for this image format `VidTestComp.mov' @ error/constitute.c/ReadImage/532.

But when I claim its an mpeg (i.e. mpeg:movie.mov) file (but not true -- just enough so ffmpeg processes it), it works without a problem

How do I write a delegate for quicktime movies? I was a little confused on the syntax of it.

As you have a delegate, either duplicate it in the system delegates file, with a input file suffix change,

Or copy it to your personal .magick/ area (so it does not get updated on a new IM install.

You could submit it here if it works for you and a developer can add it for future releases.
