Re: SUCCESS - Testing application to compare Acoustic Echo
Cancellation (AEC) in SWF11 in OpenMeetings Raju
Hi, I have the same problem as George when I attempted to use two PCs, for
a 1:1 communications I was not able to do this.
I was not able to do the following:
Send from PC1 on “stream1” --------> Receive on PC2 on “stream1”
Send from PC2 on “stream2” -------> Receive on PC 1 on “stream2”
But what happens it this
Send from PC1 on “stream1” --------> Receive on PC2 on “stream1”
Send from PC2 on “stream2” -------> Receive on PC 1 on “stream1”
If I send a second strem (strem2) on PC2 to receive on PC1, this
receive playback strem1 and not strem2.
Why?
Please answer me

Hi,
I have fixed the problem when attempt to use 2 PCc for a 1:1 communication.
The problem is in test-setup.lzx.swf11.swf file.
Now I am able to do the following:
Send from PC1 on “stream1” --------> Receive on PC2 on “stream1”
Send from PC2 on “stream2” -------> Receive on PC 1 on “stream2”

Re: SUCCESS - Testing application to compare Acoustic Echo
Cancellation (AEC) in SWF11 in OpenMeetings Raju
Posted by Vincenzo Raimondo <vi...@gmail.com>.
Hi,
Someone know how compile file text-setup.lzx to test-setup.lzx.swf11.swf ?
Please help me. Thanks
> Sebastian, Vincenzo, Raju,****
>>
>> ** **
>>
>> I did find a few small problems when testing with the “
>> test-setup.lzx.swf11.swf” application.****
>>
>> ** **
>>
>> **1) **I was able to successfully test using a single PC by
>> broadcasting on “stream1” and receiving on “stream1”. That is on my test PC
>> I would broadcast on “stream1” and then also receive on “stream1” using the
>> same PC. This worked well for testing the AEC feature.
>>
>> ****
>>
>> **2) **It seems that it does not matter what I name the two streams
>> for the Broadcast and Playback, e.g. stream1 & stream1 or stream1 & stream2
>> or George & Tony, the test application simply connects the BroadCast stream
>> to the Play-Broadcast stream on the same PC, regardless of what I name the
>> streams. I cannot connect the Play-Broadcast stream of one PC to the
>> steam started on another PC.
>>
>> ****
>>
>> **3) **As reported above in step 2, when I attempted to use two
>> PCs, for a 1:1 communications I was not able to do this, maybe I did not
>> understand how to do this?. I could only send and receive on the same PC,
>> I was not able to do the following;
>> Send from PC1 on “stream1”
>> Receive on PC2 on “stream1”
>> Send from PC2 on “stream2”
>> Receive on PC 1 on “stream2”
>>
>> What happened is that the playback on PC1 would only receive the stream
>> that it is sending, that is “stream1”, no matter what I called the “playBroadCast”
>> stream name.
>>
>> ****
>>
>> **4) **I also found that, as mentioned in Sebastian’s instructions,
>> if I ever stoped the broadcast or the playback, I had to close the browser
>> and then try again, if I was to be able to receive the broadcast again.
>> Thus between testing with “userEchoSuppression” turned on and then testing
>> with it turned off, I had to close the browser and reset up the test (no
>> problem doing this, just shows that the code does not fully close and
>> restart the connection).
>>
>> ****
>>
>> **5) **While I used the server’s domain name in the web browser’s
>> URL, I had believed that I had to use the actual IP address of the domain
>> name in the “test-setup.lzx.swf11.swf” own URL: field, but this
>> understanding was incorrect, I was also able to use the server’s domain
>> name in the URL: field. And once again, without the options “useEchoSuppression”
>> and “Use Enhanced Microphone” checked, the echo is very bad, but when
>> running the tests with the default of these options selected, the echo is
>> *greatly* reduced *on a laptop that does not have any hardware AEC
>> features*, and when using the internal speakers and microphone.
