Is it possible to prevent viewers from recording the screen or taking screenshots?
You can not configure the player to prevent screenshots or screen recordings. The only way you could prevent those actions is to use DRM protection on your content. You will need to configure the DRM on your provider’s side of things to disallow screenshots and recordings. This only works for devices which support this. It will also mean that fewer devices will be compatible with your content.
