I use the following HTML code which works fine auto-playing the mp4 in a modal window the first time in the session the button is clicked for the modal window.
<div id="modalwindowhelp" style="display:none;">
<center><img src="HELP WINDOW TEMP.jpg" height="400" width="1050">
<video controls autoplay>
<source src="whatever.mp4" type="video/mp4">
If you are reading this your browser does not support the video tag.
But if the user then leaves the modal window, then comes back to the modal window, the mp4 doesn't auto-play, it's necessary to click the "Play" button to start the mp4
How can I modify the HTML so that the mp4 auto-plays every time the modal window is opened?
Is the page closed or do they just open a new tab? If the page is closed it should play. Try using the loop attribute.
<video controls loop>
<source src="movie.mp4" type="video/mp4">
<source src="movie.ogg" type="video/ogg">
Your browser does not support the video tag.
