hello flashcomm group,
i have found an unexpected streaming behaviour when playing a stream via modem
(5000 bytes per second). The stream bufferTime is set to 3 seconds. When
streaming a video, the default behaviour should look like this:
Movie starts
Buffering 3 seconds
Movie plays buffered video
Buffering 3 seconds
Movie plays buffered video
Buffering 3 seconds
Movie plays buffered video
Buffering 3 seconds
Movie plays buffered video
Movie ends
I hope this was the correct behaviour. Here are my results:
Movie starts
Buffering 3 seconds
Movie plays buffered video
Buffering 3 seconds
Movie drops frames
Buffering 3 seconds
Movie drops frames
Buffering 3 seconds
Movie drops frames
Movie ends
The video plays only after the first buffering, after the next bufferings the
videoframes seems to be dropped. I have tested the following sample code on 3
different servers with fcs version 1.5 including the update, it never works as
expected here. The bug (?) occurs on Windows XP (localhost), Windows 2003,
RedHat 9 and RedHat Linux 7 (Mediatemple). Another server with Windows 2000
works fine! Can anybody else reproduce this here http://www.powerflashers.com
/flashcom/play/play.html (Mediatemple)? Don?t forget to use modem speed
(NetLimiter).
This is the used code:
conn = new NetConnection();
conn.connect ("rtmp:/test_record");
conn.onStatus = function (info) {
if (info.code == "NetConnection.Connect.Success") {
stream = new NetStream (this);
stream.setBufferTime (3);
stream.play ("test39");
video.attachVideo (stream);
}
};
onEnterFrame = function () {
out2 = stream.time;
};
Thanks.
