video playback speed is not enabled in the Moodle videojs
For people who want to enable it, the feature is already available in Moodle code but not activated.
a) in video-lazy.js uncommment // 'playbackRates': [0.5, 1, 1.5, 2]
b) in you root moodle folder:
grunt uglify && mdk purge
And then you have playbackrates in videojs which is such a terrific feature
PS: I suppose there is a tech reason why it is not enabled (maybe some compatibility issue?). Just curious to know what is it?
