I would not have expected that any other device could use the microphone when OM (or another application) was also using the microphone.

So it is not possible to open another browser and run OpenMeetings using the same device. It might be also that you cannot use Skype or other applications that try to access the microphone at the same time while you are using the Microphone in OpenMeetings Sebastian 2013/2/17 [email protected] <[email protected]> I have enabled the AEC feature in the client in r1446971. There might be some new options to check in the enhancedOptions. Basic guide is here: http://www.adobe.com/devnet/flashplayer/articles/acoustic-echo-cancellation.html Some of them could be made configurable in the config.xml, but I had no time yet to look into it more detailed. @Maxim If the issue with the file permission and the mxmlc executable is fixed, IMHO you can close OPENMEETINGS-529 @George You are welcome to test with your users @Timur Theoretically we can use SPEEX codec. I think SPEEX is a bit better for AEC and bandwidth usage. However my issue was the last time I used it our recordings do no more work cause FFMPEG had very poor SPEEX support. But I guess for VoIP integration SPEEX would be even more handy. Would it help you if there is SPEEX in use?

But lets check OpenLaszlo trunk, maybe somebody has made the changes needed to have swf11 and flex 4.6 available. Sebastian 2013/2/15 [email protected] <[email protected]> Plz check what SDK is used internally / what Flex (what version of mxmlc.jar) compiler is used? It might happen that this does not even compile to SWF11. My Internet is currently pretty slow, sorry it would take a while to check that here. Thanks!

If there is a nightly build from that we should use it. Can you please post the link to it? I guess you need a nightly build, building OpenLaszlo from source is not so straightforward ... you need a lot of special tools. actually without OSX its almost impossible (except you are a cygwin geek) Sebastian 2013/2/15 Maxim Solodovnik <[email protected]> I googled openlaszlo swf 11 and get the post regarding latest openlaszlo from git it is 5.0 currently On Fri, Feb 15, 2013 at 12:59 PM, [email protected] <[email protected]> wrote: Good question. Basically we have that 4.9.5 version from Raju which is using the needed flex SDK internally. I don't know if those changes ever made it into the 5.0 Version, espacially which flex SDK 5.0 is using internally. If 5.0 uses a newer SDK and supports swf11 we should use it.

Cause I can imagine Ivy will think that 4.9.5 is sufficient to download. But we need also version 4.9 because 4.9.5 does not SWF8 file format anymore. Any ideas on that? My roughest idea would be to rename the entire .tgz file so that it will treat it as if those or completely different packages. 2) And then we need to refactor the build.xml to have two openlaszlo directories (laszlo.home) options. So when compiling the SWF8 stuff it will use openlaszlo4.9 and when it compiles to SWF11 it will use openlaszlo 4.9.5 3) We need to refactor the Audio/Video components. Basically in editRecordStreamSWF10.lzx line 240 "getMicrophone" has to be replaced with: "getEnhancedMicrophone" http://help.adobe.com/en_US/FlashPlatform/reference/actionscript/3/flash/media/Microphone.html And there has to be checked which of those config values are valid (or which ones are important to be added). Cause enhanced microphones have a different option set. Some of those new variables should be made available through the config.xml (and old ones removed). @Maxim: If you could take care about 1) + 2) I would be really thankful. Issue 3) is basically something I have been testing already. Thanks!
