Set the maximum kept buffer before the current position, in seconds.
Everything before that limit (currentPosition - maxBufferBehind) will be
automatically garbage collected.
This feature is not necessary as the browser should by default correctly remove old segments from memory if/when the memory is scarce.
However on some custom targets, or just to better control the memory footprint of the player, you might want to set this limit.
You can set it to Infinity to remove this limit and just let the browser do
this job instead.
In DirectFile mode (see loadVideo options),
this method has no effect.
player.setMaxBufferBehind(bufferSize);-
