Open the browser and press f12 or fn+f12 to enter the developer tool, and enter the code in the console:
document. getElementsByTagName("video")[0]. playbackRate=16(The above 16 is the video double speed, the maximum is 16)
You can play the video at the specified speed.
Of course, you can also add "javascript:" before the code, namely:
javascript:document. getElementsByTagName("video")[0]. playbackRate=16
As shown in the picture below, save it to the browser bookmark, and click the bookmark when the video is playing to play it at double speed.
