Here's how we do the buffering control on the Flash client. Basically,
you wait for a Full or Empty status on the net stream and adjust the
buffer accordingly. Seems to work well to smooth out the bumps on a
questionable connection.
startBufferLength=2;
expandedBufferLength=15;
ns_video.setBufferTime(startBufferLength);
ns_video.onStatus = function(infoObject:Object) {
if (infoObject["code"]=="NetStream.Buffer.Full"){
ns_video.setBufferTime(expandedBufferLength);
}
if (infoObject["code"]=="NetStream.Buffer.Empty"){
ns_video.setBufferTime(startBufferLength);
}
}
