Re: Sound issue on laptop due to lack of Acoustic Echo Cancellation (AEC) that is available in Adobe Flash 10/11

[seba.wag...@gmail.com]

Yes,

this is the app:
https://svn.apache.org/repos/asf/incubator/openmeetings/trunk/singlewebapp/WebContent/src/test/test-setup.lzx

We need to compile it to SWF11 and then share the link for the SWF.

Error in openmeetings log when using chat.

[Luis Guerra]

Hi!

I have an error on openmeetings log every time a user writes a message on the 
chat window. The message is displayed, but still for every message an error is 
created. The error log is growing fast!

This is an example of an error message:
---

Any idea how to solve this? Been searching the web for days, to no avail.

Thanks in advance,
Luis Guerra.

Re: Error in openmeetings log when using chat.

[seba.wag...@gmail.com]

The logs says it is an error but just because we did mix up the log
statements.
We did write log.error($MESSAGE); instead of log.debug($MESSAGE) in the
source code.
So there is nothing for you to fix here, you can ignore this "error"
message.

Re: openmeeting mails not receiving while sending invitation for openmeetings to join a conference

[Jason Trader]

Thanks Maxim, I am not sure what was wrong with it, but I formatted my
entired system and reinstall OM, it's working correctly now, however, no
one can join my conference room if they are trying to connect outside of
lan. Can this caused by port forwarding?

Jason

I believe they receives links to http://localhost.
Try to access your OM using its DNS name accessible to others and then send
invitations

RE: Sound issue on laptop due to lack of Acoustic Echo Cancellation (AEC) that is available in Adobe Flash 10/11

[Joseph Karwat]

Both the audio and video communications aspects of OM are critical.
Anything we can do to enhance an end-user's experience in those areas will
definitely help increase OM's rate of adoption.  The AEC issue is rather
important to resolve as most users are now expecting a "hands free"
environment due to Skype. Requiring a headset is a major hurdle in
widespread end-user adoption.  Even if an IT manager installs the package,
without end-user adoption, OM just withers on the vine.

 

I have purchased the new Logitech bcc950 web conference webcam and it's an
amazing device.  It does solve OMs AEC issue, and I highly recommend it to
anyone who uses video conferencing extensively, but at $200 USD, it's rather
pricey, and it's not something one would put in a backpack. 

 

So taking a look at OM's priorities from an End-User perspective, I think
the following items are at the top of my list:

 

1.  AEC

2.  User testing to make sure all the features in both the official and
Interim releases work as advertised

3.  Making Screen Sharing and Recording easier to use

4.  Making the package easier to install

5.  Proving a proven, tested, easy, upgrade methodology for IT managers
to upgrade to newer versions of OM. 

 

While I am not a programmer I can offer support in testing and would be
pleased to lead an effort to organize the community to fully test the
Official and interim releases.

 

I really like OM and its community and believe that OM has a very bright
future.

Sebastian,

 

I am sure there are others than myself who would appreciate if we could
implement Flash's AEC.

 

I am not that skilled with the code or compiling but if I can help with
testing please let me know how.  That is if someone can build the
"audio/video sample application to SWF11", I might be able to test it out?

 

Thanks,

 

George Kirkham

Hi George,

maybe we can make upgrade the audio/video sample application to SWF11 to
have a quick look at all the feature currently available in flash player.
We have such an sampler application, that has a checkbox for all the
available settings where you can make a simple 1:1 call via Red5 and test
everything.

I think this should be done upfront. Otherwise its more a mystical thing
that happens inside the application. If it works in the sampler it
will/should work in OpenMeetings.

Maxim,

Adobe Flash will only handle Echo Cancellation if the client side Flash
Application calls Flash's "Enhanced audio API".

 I would greatly recommend that OpenMeetings should implement Echo
Cancellation, if possible via Flash since this is the platform that
OpenMeetings is currently using.  The current Echo issue of means that we
only use OpenMeetings for its whiteboard and Video sharing.

html

In addition to acoustic echo cancellation, enhanced audio also provides
noise suppression. Previously, Flash Player only provided noise suppression
for Speex audio. The new noise-suppression scheme is applied to all captured
audio samples. Noise suppression is controlled by the already-existing
noiseSuppressionLevel property of the Microphone class and is enabled by
default. Setting noiseSuppressionLevel to 0 will disable noise suppression.

Enhanced audio has a couple of limitations:

.You cannot use enhanced and non-enhanced audio at the same time.

.You can only use a single enhanced audio capture at any given time.

 Operation of enhanced audio is controlled by the enhancedOptions property
on your Microphone object and the MicrophoneEnhancedOptions class. The class
has the following properties:

.MicrophoneEnhancedOptions.mode selects the operation mode for enhanced
audio. For possible values, please see the MicrophoneEnhancedMode class. The
default value is MicrophoneEnhancedMode.HALF_DUPLEX for USB capture devices
and MicrophoneEnhancedMode.FULL_DUPLEX otherwise.

 .MicrophoneEnhancedOptions.echoPath specifies the echo path length (in
milliseconds). A longer echo path means better echo cancellation but also
introduces longer delays and requires more processing power. The default
value is 128; the only other possible value is 256.

RE: problem with the whiteboard. only one page !

[Didier Orlandi]

Hi  Maxim,

 

Thank you for your answer, but page navigator doesn’t work !

When I press the button, nothing happen. I just try to pass the page of a pdf 
or a ppt.

Do you think it’s a problem with the installation of the software swftools?

I had already reinstall swtools image magic and I have always the same problem.

Do you have any ideas?

Thank you very much.

 

Didier

black screen when screen sharing

Hi!

 

Seems like an old issue but still: when I share my screen, other
participants see only black rectangle + white cursor.

 

OM 2.0 + java 7 installed. 

 

Couldn't find the solution while googling L
