Thread used for testing images/animations. In my case an mp4 animation created with ffmpeg.

This image uses a -pix_fmt yuv420p option.

Tried it on two browsers. Chrome and believe it or not, IE 11, and it works fine.  :)

Not happy to hear that Sterks. Unfortunately I cannot test that device myself. What I can do is to find another file that works and compare with mine that does not. 

Are you able to see the mp4's that A-team posted, like in this post (and many others) :

testing avi. testing mp4
settled on

 ffmpeg -i tst2.gif -crf 29 -pix_fmt yuv420p -vf "scale=trunc(iw/2)*2:trunc(ih/2)*2" tst2e.mp4

-crf 29 the higher the number the lower the quality, smaller file
-pix_fmt yuv420p better chance of working in all browsers (same as Wipneus)
-vf prevents odd number of frames

probably still doesn't work for everyone but tested ok in firefox and edge on win10
