I am just putting a drop of LCCS 10.3 swc that supports echo cancellation based on player 10.3 beta release yesterday. Its a local build for me and not tested and it doesn't have the multicast stuff either( as I just built it on our player 10 swc). I just wanted to throw out something for ppl to try out echo cancellation.
I am attaching the swc
Things you will need if you are using flex builder
a) you need to have additional compiler option as -target-player=12
b) You need to have the 10.3 playerglobal.swc in your Flex SDK
c) You need to have flash player 10.3 installed on your machine.
Since there are additional classes , we will in future have to give out a new swc for 10.3 in all likelihood. But for now, test and let us know how AEC works for you.
Hope this helps
Hi Nigel & Arun,
Thanks for referring me back to this thread in your post on AEC in http://forums.adobe.com/message/3709913#3709913. That's great that you have an prerelease AEC version of the swc for each of your releases.
Since I'm using the prerelease swc (and source code) that includes your initial CPU spiking/ratcheting fix, does that also include the code necessary to test AEC? If not, would it be possible to get the swc and source that includes both the CPU spiking/ratcheting fix and AEC?
We build and release the 10.3 swc along with our regular release. So
10.3 swc would have all the changes we made since our last release. So
you can expect the 10.3 swc with the CPU spiking/ratcheting fix in our
next release which is very soon.
Ah great - thanks Arun.
So just to confirm, that 10.3 .swc and source code will include access to AEC as well?
Thanks Arun, having access to the source to 10.3 will be very helpful for debugging.
Will that have AEC, or if not, could another AEC patch (with the understanding that our mileage may vary) be made available?
Just to confirm, based on items from other threads, you do echo cancellation for us and we don't need to set
view.audioPublisher.useEchoSuppression = true;
view.audioPublisher.codec = SoundCodec.SPEEX;
useEchoSuppression by default is set to false, and codec is set to SPEEX by default. But AudioPublisher.useEchoSuppression is a wrapper to the "Reduce Echo" field in the Flash Player Microphone settings panel, and "useEchoSuppression" functionality is ignored in enhanced mic (with AEC support)
So just to double-check, you're saying that there's nothing we need to do from our side to enable AEC if we're using the 10.3 SWC then?
We're asking because we've been hearing a fair bit of echo recently even when running under 10.3 with AEC, but the users in question were speaking loudly and there were other computers nearby connected to the same room.
Yes Trace, You don’t have to do anything to enable AEC.
Let us know if you hear echo under a different setting.
I have no echo now with the new swc. Audio is getting close to perfect. I still make those two calls in the API, but not sure if it's necessary or not.
I have been out of the "LCCS" game for a few months working on php for a project, so I apologize for my ignorance here, but am I correct in thinking the AEC 10.3 swc has not been officially released yet?
I just reinstalled the LCCS SDK Navigator, as well as downloading the latest SDK, and the library is still at version 10.1! Am I missing something or is 10.3 still in beta?
Sorry to sound like such a NOOB, but I tried installing the LCCS 10.3 build and I can't even get that far! I did install the Flex 4.5.0 SDK without trouble, however, now I am getting errors and my LCCS app. will no longer compile!
Did this, but still errors!
I found "playerglobal.swc" in C:\Program Files\Adobe\Adobe Flash Builder 4\sdks\4.5.0\frameworks\libs\player\10.2\ and replaced the one that was already there with the new one from the current LCCS 10.3 build, but I keep getting the following error:
unable to open 'C:\Program Files\Adobe\Adobe Flash Builder 4\sdks\4.5.0\frameworks\libs\player\10.2\playerglobal.swc'
I have absolutely no idea what I'm doing with this!
Did this without a problem!
As far as installing the actual LCCS 10.3 build, I am utterly clueless! How does one go about doing this without screwing up the currently working LCCS builds? Do I just copy/paste it alongside the LCCS 10.0 and 10.1 folders in 'C:\Program Files\Adobe\Adobe Flash Builder 4\plugins\com.adobe.lccs\libs\'?
I went to http://jfvisuals.blogspot.com/2011/06/acoustic-echo-cancelation-working.html page where he explains what to do, and although it was informative, he doesn't explain how to do it!
I'm literally pulling my hair out here! Please help
Can you post the errors you are seeing?
I am using the 10.3 swc and have got it working by following the steps posted by Basu at the beginning of this thread. Is it possible that you are compiling with the older playerglobal.swc?
Follow these steps, and let us know if your app still fails. These steps
are specific to 4.5 flex SDK
1) Create directories 'C:\Program Files\Adobe\Adobe Flash Builder
4\sdks\4.5.0\frameworks\libs\player\10.3' & 'C:\Program Files\Adobe\Adobe
Flash Builder 4\sdks\4.5.0\frameworks\libs\player\12.0'
2) Copy 10.3 playerglobal.swc into the directories you just created
3) Add swf-version=12 to your project compiler properties. (Right click on
your project, Properties + Flex Compiler + Additional Compiler arguments)
4) Also set Flash Player Options to Use a specific version and set it
10.3.0 (roperties + Flex Compiler + Adobe Flash Player Options)
Thank you for your response! I did finally get it working, however, now a few errors have come up (which probably have more to do with compiling under the new SDK rather than an incomplete installation).
Yes, this seems that this was the case What I did was physically create a folder called "10.3" and copied/pasted the 10.3 playerglobal.swc inside of it! Is it ok to do this? Did you do the same thing? I just don't know if there is a "proper" way to do this or not.
I did the same thing with the LCCS 10.3 SDK. I just copied and pasted the SDK in a folder I physically created in the player folder. Again, I'm not sure if this is the way to do this, but I found no alternative!
I had also forgot to include "swf-version=12" in my compiler arguments originally.
Thank you so much for this!
I managed to get it working, but will go over everything again (as per your directions) to make sure I didn't miss anything!
One last question - I installed the new LCCS 10.3 SDK by copying and pasting it into the 'C:\Program Files\Adobe\Adobe Flash Builder 4\plugins\com.adobe.lccs\libs\' folder. Is this ok? Is there a better way to "install" it?
