As per the reply from internal folk:
You can overlay the html, where the vedio tag is present and change the preload="metadata". it will take meta info only after that.
<video width="480px" height="270px" controls preload="metadata" controlsList="nodownload"><source src="" type="video/mp4"></video>
Just remember controlsList="nodownload", is used to hide download option. You can remove it as per your need
