Hi Justin, thanks for replying. Yes, the plugin is enabled. I also disabled multimedia plugins filter.
I looked at the source code through inspect and its the default videojs player that comes with moodle.
Surprisingly, the div class is <div class="mediaplugin mediaplugin_videojs"> for the player, which leads me to believe it might still be using the default media player videojs player. If I disable the player, it simply runs a <video> element with the source.
I upload the item as a url by uploading a url element (as shown in picture).
I currently have the MathJax, Activity names auto-linking, Videoeasy filter enabled.
