There are various default buffer values for ExoPlayer:

B4X: 
bufferForPlaybackMs    2500
minBufferMs    15000
maxBufferMs    50000
bufferForPlaybackAfterRebufferMs    5000

Is there a way using JavaObject/Reflection to change these values?

Basically, when I start Exoplayer, the stream doesn't start playing until it reaches that 2500ms default value (bufferForPlaybackMs), but I would like to set this to 1000ms so the stream will start quicker.
