I'm trying to diagnose a problem with another program (Pure Data) that may be caused by a defect in imagemagick or gmerlin. Here's the original bug report https://sourceforge.net/p/pd-gem/bugs/222/
I'm running pd extended 0.43.4 on Ubuntu 13.10. I've install gmerlin 1.2.0 in order to play animated gifs within that program.
If I play gifs made in imagemagick they only play once and don't loop. If I play ones made in GIMP then they loop forever. What is GIMP doing that imagemagick isn't?
Here is the original gif file http://i.imgur.com/npym0Bq.gif
For completeness I reencoded it in imagemagick http://i.imgur.com/WvBNnZ4.gif (convert originalgif.gif -coalesece images.png ; convert images*.png newgif.gif)
Here is the new gif, saved in GIMP http://i.imgur.com/51YOrMS.gif and a screenshot of the parameters I used when svaing the gif in GIMP http://i.imgur.com/ZFc4iwl.png
Can anyone help?
Looping is not supported at all, so I don't know how gmerlin would do it.
One difference I see between the gifs is, that WvBNnZ4.gif has a zero frame duration (and thus an infinite framerate) while 51YOrMS.gif has a framerate of
