convert depending on MPlayer

[Niels Serup]

Hello list

When I ran this command:

convert test.avi frame%03d.png

I got these errrors:

sh: mplayer: not found
convert: Delegate failed `"mplayer" "%i" -really-quiet -ao null -vo
png:z=3' @ delegate.c/InvokeDelegate/1015.
convert: missing an image filename `frame%03d.png' @
convert.c/ConvertImageCommand/2775.

Now, I don't have MPlayer installed -- but I do have a copy of FFmpeg.
And when I ran this command:

ffmpeg -i test.avi -an -sameq -r 1/5 frame%03d.png

I achieved my goal, which was to extract screendumps from a video file.

Considering that MPlayer and FFmpeg clearly has the exact same feature
in this case, would it be possible to make convert try to use FFmpeg if
no mplayer program is found? I consider it a bug to depend on a program
that's not there.

I am using Trisquel 3.5, based on Ubuntu 9.10.

Recent versions of ImageMagick use ffmpeg rather than mplayer. Consider
upgrading.
