Change speed of Edpuzzle video

explainer.md

Edpuzzle aggressively reverts the playbackRate of a <video> element, so you can't simply change it to increase the speed. Thus, a more aggressive response is necessary to combat it.

Firstly, we get the <video> element:

video = document.querySelector('video')

Then, we get the setter function for the playbackRate property using Object.getOwnPropertyDescriptor(HTMLMediaElement.prototype, 'playbackRate').set. It is called with the <video> element as this and with speed as the new value. This way, the <video> element is properly notified of the speed change by simulating assigning a value to playBackRate directly (ie using =).

Object.getOwnPropertyDescriptor(HTMLMediaElement.prototype, 'playbackRate').set.call(video, speed)

After that, to prevent Edpuzzle from changing it back, we make playbackRate unwritable, so they can't simply set it:

Object.defineProperty(video, 'playbackRate', { writable: false })

Of course, if we can change the speed this way, so can Edpuzzle, so this might not work in the future.

paste-into-console.js

// Paste the following code in the console (right click > inspect element, then click on the Console tab) on the Edpuzzle page

speed = 2 // Change this to the speed (eg 2 for 2x speed)
video = document.querySelector('video')
Object.getOwnPropertyDescriptor(HTMLMediaElement.prototype, 'playbackRate').set.call(video, speed)
Object.defineProperty(video, 'playbackRate', { writable: false })

I found a fix using a Inspect element bookmarklet and deleting a lot of stuff around the video which unlocks the video so i just skip through refresh the page and answer the questions.

can you make it so a can fast forward throught the video

Yes pls Fix it.
