removing progress bar from video

[Allie Silverman]

Part of my study is assigning people to watch different videos. I am hoping to restrict their control over the progress bar so that they cannot replay or skip to the end (to ensure that everyone is watching the entire video once and no more). I've looked over videojs documentation for the control bar (https://docs.videojs.com/controlbar) and tried a couple of things but cannot get anything to work. Any insight would be great! 

This is the code I am using currently:

<div class="text-center">

<video controls = "controls" autoplay="autoplay" poster="https://i.ytimg.com/vi/koKuyLE8y8s/maxresdefault.jpg" width="640" height="360" >

<source src="https://cdn.jwplayer.com/videos/DQDe3ikJ-64nbePyI.mp4" type="video/mp4" />

<object type="application/x-shockwave-flash" data="http://releases.flowplayer.org/swf/flowplayer-3.2.1.swf" width="640" height="360">

<param name="movie" value="http://releases.flowplayer.org/swf/flowplayer-3.2.1.swf" />

<param name="allowFullScreen" value="true" />

<param name="wmode" value="transparent" />

<param name="flashVars" value="config={'playlist':['https%3A%2F%2Fi.ytimg.com%2Fvi%2FkoKuyLE8y8s%2Fmaxresdefault.jpg',

{'url':'https%3A%2F%2Fcdn.jwplayer.com%2Fvideos%2FDQDe3ikJ-64nbePyI.mp4','autoPlay':true}]}" />

<img alt="control" src="https://i.ytimg.com/vi/koKuyLE8y8s/maxresdefault.jpg" width="640" height="360" title="No video playback capabilities, please download the video below" />
