Here is a sample i did quite a while ago about spritesheets. In it a character running. Several buttons below it. Among them 2, 1 to slowdown speed and 1 to make him run faster. Click multiple times to see the effect.
Similar technique(s) will work for video offcourse. As the Lectora mediaplayer is based upon the Mediaelement.
Sounds like a interesting option. I got no clue how to add a plugin to an existing mediaelement. HTML5 video has default the playbackRate property.
For audio you offcourse need something else.
You could for example use this audio library.
Checking the documentation for Buzz
you quickly find that there is a speed property. So you can speedup/slowdown audio with Buzz.
Set the playback speed where 1 is normal speed, 2 is double speed, etc.
