Video is stuck when starting playing on real device with Safari

Hi,
I’m using:

  1. iOS 9.3.2 device
  2. Appium 1.5.3 - with “Use Mobile Safari” capability
  3. appuimlibrary for robot framework

My test is to navigate to dailymotion.com site, pick up a movie and play it.
While the video start playing it stuck after 2-3 seconds!
No error is retrieved from appiumlibrary, while in appium log I can see:
