convert-im6.q16: cache resources exhausted

On some video files (not all) I get the follow error and the produced file is empty :

$ gifify --colors 255 -o x.gif --resize '800:-1' VID_20170820_124826.mp4

The video was 30 seconds long, I ended up doing three runs of 10 seconds and that works...

Same problem. Tried making a gif out of a 45 second gif. Both this and the following script ends with the same error:

$ ffmpeg -i demo.mp4 -r 10 -f image2pipe -vcodec ppm - |   convert -delay 5 -loop 0 - output.gif

It seems that issue could be closed, since the workaround described in #396 works great (ie. increasing the available memory in the /etc/ImageMagick-6/policy.xml file).

Hey @AlexandreBonneau, can you give a link to the workaround? thanks!

[AlexandreBonneau]

@vvo I was referring to the issue #396 mentioned just above. I edited my comment to add the link.
