I intend to embed a number of videos in my classes, however I don't think everyone wants to listen to me talking slowly. How can students increase the video playback speed to 1.5x or 2.x?
I found this tracker ticket to add playback rates for VideoJS: https://tracker.moodle.org/browse/MDL-58673
You can vote or comment in the ticket to try to bring it to the next version of Moodle. Also, if you aren't afraid of code, there are steps in the description about how to enable playback rates.
Well, I voted and commented (that the steps there don't directly work in the pre-packaged moodle VM I got).
I ultimately had to use the H5P plugin, and then completely change the format of the class because the plugin can't be used to show videos in lessons :\
