I think it might even be recommended to start with a very low bitrate<br>
alternative, then based on the speed it took upgrade to better quality<br>
(bandwidth). It is a kind of "fast start". The same behaviour is<br>
possible for seeking.<br>
Of course it might be anoying to have quality change/variation, so<br>
there is a tradeoff. I guess it should be an option for the end-user<br>
that would modify the heuristic. Some user might prefer quality over<br>
fast start (or reverse way).<br></blockquote><div><br></div><div>I agree that an option would be best.

<div>But I would not want to start on lower quality. Given that many internet connections these days are faster than most reasonable stream bitrates (~ 10Mbit).. I would want VLC to start playing even before the first segment is downloaded completely (prefetch=0).</div>

<div>Prefetching an entire 10sec segment in 8mbit on a 10mbit connection takes a full second and I would like playback to start to in <0.5 sec</div><div><br></div><div>Jeroen Ost</div></div>
