Vimeo video not working on iPhone

[LiSkynden]

I am using PopTrox on this site:
http://boudoir.jirina.fi/
(scroll down to PORTFOLIO and down to last two thumbs)
video is not working on iPhone5 iOS8.3 with Safari. It does work on iPhone with Chorme tho, but "crashes" when turning the phone ... check this video

I copied the PopTrox Vimeo code from here
https://github.com/n33/jquery.poptrox
and used it like this
< a href="https://vimeo.com/121874333" data-poptrox="vimeo,800x480" class="image fit from-left">

but i dont think there's anything in that cause the video works on iPhone with Chrome.

Sorry for newbie question but I now noticed i have the v2.3.2 version ... and the newest is 2.5.1? Should i download that...?
