Special player for Wordpress video sites?

[HaveAGoodLuck]

The website includes embedded codes obtained from sites like vidmoly and filelion. Upon inspecting the page source of some movie and adult sites, I noticed they use a unique player and do not indicate the source of the video. Are these sites hosting the videos on their own servers or using a custom player? The main question is, if they use embedding, I would like to install a custom player on my WordPress site. Do you have any recommendations or know of a place where custom players are available for purchase?
