[mgp-users 00774] Re: Problem with MagicPoint1.09 and mng-animations

I had problems with those as well. I checked the past emails in this
group, and the following recipe works for me:

- start X without windowmanager (maybe start just an xterm)
- start mgp
- use the system command to call mpeg_play like this
  %system "mpeg_play -quiet -dither color -controls none -position
+350+300 -loop file_to_show.mpg"
- put the system command last on the slide, so everything else in drawn
first.

This is not ideal, as the position is now fixed  (and will be wrong on
another screen resolution), but I couldn't get xsystem to work (partly,
because mpeg_play doesn't support the -geometry parameter ...).

I also tried to convert my mpeg into an mng using ImageMagick as you
described, but the movie became very big (50MB) so this was pointless. I
didn't try the -compress switch of convert. Does that make the file
smaller?

Hope this is of interest,

Hans
