I recently play with network stream startup time
and it isn't really nice to wait 10 and more seconds until user really see
something

for example for hls stream
AUTO_PREROLL_SIZE_BYTES                  2 * 1024 * 1024  => 2MB
AUTO_PREROLL_NOT_SEEKABLE_SIZE_TIME      10 * GST_SECOND

and after it preroll it is switch to 
AUTO_PLAY_ADAPTIVE_SIZE_BUFFERS 2

but still we have 10s PREROLL TIME in second multiqueue

I know that most of this values isn't problem for playback from local file
system
but for network streaming it is long wait time.

I think we can tune it with  DEFAULT_HIGH_PERCENT     to something like 20% for
network streams and first multiqueue can stay in buffers mode
