[Bug 1012378] [NEW] convert to mpeg fails due to ffmpeg pass argument

[rt_davies]

Public bug reported:

A simple call to convert to create an mpeg from a few jpegs fails with
the following error message:

convert: delegate failed `"ffmpeg" -v -1 -mbd rd -trellis 2 -cmp 2
-subcmp 2 -g 300 -pass 1/2 -i "%M%%d.jpg" "%u.%m" 2> "%Z"' @
error/delegate.c/InvokeDelegate/1058.

I compared line 83 of /etc/ImageMagick/delegates.xml to the latest
release at http://www.imagemagick.org/source/delegates.xml and found the
only difference is an additional flag "-pass 1/2" in the Ubuntu
package's version.

Removing the "pass" argument fixes the convert error.  I notice that the man page for convert doesn't mention a pass argument.
 
I propose the solution is to remove "-pass 1/2" from delegates.xml line 83.

Here is more information about my configuration:
