How to install a video player?

Dear Team,

Could you please let me know how we can play a video bitstream on a player, instead of downloading it? I read the document as it has an HTML5 player. I have also tried with video.js. However, the bitstreams are downloading when we click on the Download button. How can we activate the video player on Dspace DSpace-CRIS 8? Thank you in advance for your help.

Regards
