Public functions

getMediaClock

fun getMediaClock(): MediaClock!

If the renderer advances its own playback position then this method returns a corresponding MediaClock. If provided, the player will use the returned MediaClock as its source of time during playback. A player may have at most one renderer that returns a MediaClock from this method.

Returns
`MediaClock!`	The `MediaClock` tracking the playback position of the renderer, or null.
