So I have a website like YouTube and I want to monetize it. It uses simple HTML5 video player to display dynamic videos. I don't want to integrate any other player because my site is designed for HTML5 players. I have watched couple of videos about this, and neither of the source codes worked (It didn't display the ad itself). I use Adsterra VAST tag, so I don't know if it's their problem or not. I would be very happy if someone can help me with documentations or sample codes. Thank you!
