Is there any way to track

Hello.

I am trying to use some videos in my Qualtrics survey.

I want video autoplay, hiding controller and preventing right-click and F5.

But it seems that at the iOS environment, video autoplay does not work.

So I just want to check if people have watched the video.



I found almost the same question and the kind answer, but it is dealt with youtube iframe api.

I prefer html5 video player because I cannot manage some features in the case of youtube video..(e.g. hiding controller and preventing right-click)



Can someone please help me out?
