Movies plugin by wonderboymusic allows you to use simple functions in your theme to display videos you have attached to Posts/Pages/Custom Post Types in your Media Library. Your player is styled 100% with CSS/images (if you want). The video player uses the MediaElement (by default, or VideoJS – you pick!) library and your browser’s native HTML5 capabilities when available with a fallback to Flash when necessary. Allows you to play video inline on mobile browsers that support HTML5 Video. Video metadata is written to the page using the hMedia micro-format for semantic markup.
