Buffering works by handling it inside the application as desired.
Usually you would set your pipeline to PAUSED when you get BUFFERING
messages with percent<100, and set it to PLAYING when you get BUFFERING
messages with percent==100.

The percentages in the buffering messages are scaled according to the
high/low properties on the multiqueue, so setting high-percent=100 is
usually not a good idea.
