Yii2. Getting video file parameters?

Question

JavaScript

Hello, there are two questions)),
1) An application on yii2 with a video, I need to add the duration of the video to the database when adding a video to the site. (maybe there is some kind of extension for working with video like for pictures like yii2-images, I did not find it)
2) How to get random frames from a video in automatic mode, so that when I hover over the preview, I change frames, such as preview (here JS with everything is clear to him), but with the automation of obtaining these frames, not very much.
Who can tell? :)
