How to install a preview poster

To set the image as a preview before the start of playback, specify the URL to the picture with the parameter poster in the code

var player = new Playerjs({id:"player", file:"//site.com/video.mp4", poster:"//site.com/image.jpg"});

You can customize poster in the builder Settings / Poster

By default, the poster is stretched to the full size of the player. In PRO it is possible to set Special size and position (free template with example).
