With video playback

Currently, the playbackSpeed property ofplayer currently only supports the whiteboard itself. During playback, the audio and video mounted by media will not be affected byplaybackSpeed for the time being. The whiteboard itself operates audio and video through videojs, so you can modify the playback rate of audio and video through thevideojs player.

const videoJsId = "white-sdk-video-js";
const mediaPlayer = videojs.getPlayer(videoDom);
// https://docs.videojs.com/docs/api/player.html#MethodsplaybackRate
mediaPlayer.playbackRate(1.25);

The media player of the Vue user can be a DOM node, with slightly different operations.
