Hi Pushparaj, hi all,
 
in a previous mail somebody mentioned that a stagnat video is proably
connected with a high network latency.
ived check this with a tool to simulate WAN connections and i was able
to adjust packetloss, latency and bandwidth.
 
indeed, after increasing latency to 200ms the buffer is running empty,
rebuffers and runs empty, and so on.
its getting more worst after setting packetloss to 1% or higher.
and at least downsizing the bandwidth has also a stucking effect (of
course).
in generell you can say: the more far the client the more stagnant the
video.
 
the full test is attached (latency from 200ms to 400ms, 1% packetloss,
down to 512kbps bandwidth). you can also download it here
http://www.versicherungen-abc.info/BufferEmpty.xls
 
with the same networkparameters i also tryed progressive download over
http. This worked fine and smoothly.
 
May be increasing the os tcpwindowsize could help. dont know, havnt test
it.
 
Another solution mentioned by somebody at this list, is to adjust the
buffer dynamic.
 
something like this:
--------------------
startBufferLength  = 2;
expandedBufferLength = 15; 
 
my_ns.setBufferTime(startBufferLength);
 
my_ns.onStatus = function(info) {
 d_console("onStatus: " + info.code);
      if (info.code=="NetStream.Buffer.Full")
       my_ns.setBufferTime(expandedBufferLength);
      if (info.code=="NetStream.Buffer.Empty")
       my_ns.setBufferTime(startBufferLength);
}
--------------------
but the buffer is still running empty. the playback is just starting
quicker after an empty buffer "if (info.code=="NetStream.Buffer.Empty")
my_ns.setBufferTime(startBufferLength);"
 
Hopefully this will be fixed soon (if its a red5 prob??).
 
greetings
-Adam-
