Bilibili believes that everyone is familiar with it, and Flv.js is the HTML5 Flash video (FLV) player open sourced by the bilibili website, purely native JavaScript developed (written by ECMAScript 6), no Flash is used.
Its working principle is that Flv.js parses the flv file stream in JavaScript, and encapsulates it into fmp4 in real time, and feeds it to the browser through Media Source Extensions, realizing the playback of FLV format videos.
