JSMpeg.Player API

A JSMpeg.Player instance supports the following methods and properties:

.play() – start playback

.pause() – pause playback

.stop() – stop playback and seek to the beginning

.destroy() – stops playback, disconnects the source and cleans up WebGL and WebAudio state. The player can not be used afterwards.

.volume – get or set the audio volume (0-1)

.currentTime – get or set the current playback position in seconds
