errors and AV delays

[GoogleCodeExporter]

Which version of OpenMeetings are you running?
r998 from SVN

What's your operating system on client and server side?
Win2003 Server & WinXP Pro

Is it a problem related to the client/usability or server-side?
Server

Did you have any trace/debug output?
Yes, error log is attached
_____________________________________

I installed the latest source from SVN, and I am using latest version of 
Red5 (0.7.0). The application runs and I can login to a conference.. but 
on a local network running two clients I see a gradually increasing delay 
between audio and video... also screenshare does not launch (see attached 
log)

Why do I see this delay in AV (both clients have Flash 9 player)?

Why doesn't screenshare launch?

Why do I get so many errors in my log?
For example see below... surely these are not errors?

I am also getting lots of debug messages in my log.. how can I turn these 
off?

Many thanks in advance
Phil

Hi !

I have absolutely no idea about how to resolve your problem, but I'm very 
interested
in finding a solution for it.

First of all, do not be afraid of all those [ERROR] you see in your logfile. 
Those
are only debug logs, but are declared as errors in the source code. So the 
problem is
in the source, not on your side ;)

Secondly, it could be interesting to know which version of the Flash plugin you 
are
using, which browser (with full version),...

We have had some errors with a specific (old) version of IE6 which disappeared 
when
we upgraded it.

Hope this can help.

Mathieu

One precision about the ERRORs in the log file: I'm only speaking about the 
lines you
pasted here. There might be other lines that are *real* errors ;)

If you want to turn of the DEBUG messages, you have to configure properly the
log4j.properties file and set the log level to INFO (show INFO and ERROR 
messages) or
ERROR (show ERROR messages only)

OpenMeetings is for the moment tested with red5 0.6.3 not with red5 0.7
red5 0.7 has some major changes in logging. I cannot guarantee any results in 
red5 0.6.3

I did also test with 0.7 but just to make sure that it is working not 
developing with
it. I propose changing soon.... basically 0.7 brings changes in Clustering et 
cetera
not in Network et cetera.

And what do you mean by *delay*? There is no hardware/software trick to solve 
this
issue! Only thing which might could be done in future is to solve:
http://code.google.com/p/openmeetings/issues/detail?id=318
=> so the user gets a button to *resync* his Audio/video by restarting his 
Stream.

In general it could be improved if red5 has some improvements but in most cases 
delay
is connected to bad bandwidth.
Also *delay* != *delay*
there is:
1.) delay after a period of time
2.) delay between audio and video (out of sync) after a period of time
3.) delay immediately after starting the conference (usually connteced to bad 
bandwidth)
4.) delay cause Flash-Plugin is at 100% CPU (Linux Flash Plugin)
5.) delay cause of Webcam/Driver Issues

case 1 and 2 maybe be solved by Issue 318 but Issue 
case 3 may be improved by adding / analyzing 
NetConnection.InsufficientBandwidth events 
case 4 may be solved by changing Frame-Rate of overall Movie Issue317
case 5 may be solved by adding a test app Issue 303

sorry the first sentence of my previous comment should have been:
*OpenMeetings is for the moment tested with red5 0.6.3 not with red5 0.7
red5 0.7 has some major changes in logging. I cannot guarantee any results in 
red5 0.7*

Mathieu..thanks for your replies

Sebastian..also thanks for your reply...yes, I was reading about the logging 
changes 
in 0.7 Red5 today..and I downloaded your latest SVN build to try out 
logback.xml. I 
was able switch off DEBUG message by editing logback.xml in the Red5/conf 
folder but 
it didn't seem to work as application level

The delay I am talking about is when one user speaks or moves.. this is 
heard/seen 
some seconds later on the other client.. typically this starts at about 1 
second and 
steadily grows. Since I eliminated the DEBUG log entries this has improved but 
still 
happens. I am on a local network so bandwidth should not be a problem(?)

I guess this is Red5 problem.. I tried to test this on your live system but 
most of 
today it has been locked up.. ie. unable to get moderation in abandoned 
conferences

Many thanks for your reply.. I will wind back version of Red5 and try again
