Videos in FS questions
by Seven Du 30 Mar '11

30 Mar '11

Hi, I finally got a chance to play with videos in FS. I read some discussions of mod_fsv and mod_mp4, and I haven't try mod_mp4 but I think video passthrough is enough for me for now. Videos in conference. In my test video is sort of works, it seems that all parties see the video of the current speaker ( who is in control of floor). I didn't find much info about floor only in a email said it's auto selected and we have not much use about that param. So my questions are: - is it possible to lock the video of one speaker? so it's like a broadcast conference where all seeing and listening to one speaker? I think we can get that by mute all others but it would be good if we can control - if we can lock one speaker's video, can we manually switch to another speaker's video? - If we could use sth. like mod_mp4, is it possible to mix videos lively? I guess it would be a performance killer. - how to record videos in a conference? is it possible to conference xxx dial loopback/9193 to record video ? (I haven't try that). I'd like to work on a patch to make the above work if not already supported. Also, other ideas about cool things with video in FS are welcome. Talk to flash I heard someone started working on a mod_fmtp like things, how's the progress? I'd like to take a look maybe I can help working on that. I now there's already some sip-flash gateways out there but seems that only adobe fms supports rtfmp: http://askmeflash.com/article/10/comparison-wowza-vs-fms-vs-red5 Thanks, 7. -- About: http://about.me/dujinfang Blog: http://www.dujinfang.com Proj: http://www.freeswitch.org.cn Sent with Sparrow

Re: [Freeswitch-users] Freeswitch latest source rebuild issue under Windows
by Andrew Keil 30 Mar '11

Jeff, I have tried the build again with no luck - same main fatal error as before. Followed from http://wiki.freeswitch.org/wiki/Installation_for_Windows Note that building for Windows within a tree that has previously been built for a different platform will result in numerous errors and build failures. To resolve, delete the following generated files: libs/apr/include/apr.h libs/js/config.h libs/js/src/jsautocfg.h libs/js/nsprpub/pr/include/prcpucfg.h libs/iksemel/include/config.h libs/xmlrpc/xmlrpc_config.h libs/libsndfile/src/sfconfig.h; also rename libs/win32/libsndfile/config.h to libs/win32/libsndfile/sfconfig.h {Note: this line is the only one that I actually did anything - since the rest of the files do not exist} libs/sofia-sip/libsofia-sip-ua/su/sofia-sip/su_configure.h Then Rebuild the solution. Tried to rebuild three more times with no joy - same main fatal error as before. See attached.

FS performance test -Hard disk alway busy when registerred 500 users
by Charles 30 Mar '11

30 Mar '11

I'm makeing the load test of the FreeSWITCH, I registerred 500 users to FS, and make NO calls, then the LED of Hard disk alway blink meaning it always busy... below is my hardware configuration, would someone can help how to improve the performance? thanks in advance. i tried to increased the nonce-ttl to 600 from 60 tring to decrease the times of writing db. however it doesn't make help... attached is the internal.xml for reference. Windows server 2008 64bit. CPU: Intel Core2 Duo L7400 with Intel 310 1.5GHz, Memory: 2G, bit: 64bit, HD: 160G P.S. i can think about RAMDISK, however, I�m afraid of it is so stable... if it can be increase the performance by HD itself, it will be great.

Freeswitch latest source rebuild issue under Windows
by Andrew Keil 30 Mar '11

30 Mar '11

To Freeswitch developers.... I previously posted this to Freeswitch-dev and it is waiting Moderator approval. However Darren Schreiber suggested I post this here. OK. Here goes, what I have done so far... 1) Setup a Virtual Machine running 32-bit XP SP3 (with all Critical Updates applied). That way I can quickly go back in time and try an install again if necessary. 2) Since I noticed that you now support Visual C++ 2010 Express, I downloaded and installed that (without the option for SQL Server Express 2008). 3) I also then installed the Windows SDK (7.1 (the latest version)). The reason for this is when I download your latest build of Freeswitch 1.0.7 today it complained about 64bit settings throughout various project files when opening Freeswitch.2010.express.sln 4) Then I simply downloaded your latest build from http://latest.freeswitch.org/ and extracted it out to c:\FreeSWITCH (so that there is a sub-directory freeswitch-1.0.7 below it with all the files) - this looks the same layout as the Freeswitch book example, except 1.0.7 version instead. 5) Opened the Freeswitch.2010.express.sln 5.1) Stated inside the Visual Studio Output Window: "Some of the properties associated with the solution could not be read." 6) Built the solution via F7 See attached for the build errors from Visual Studio. I guess my questions are the following: Q1) Should I be running Visual C++ 2010 Express or Visual C++ 2008 Express - it does not matter to me, however I always like to move with the times? Q2) Was I right in installing the Windows SDK (http://msdn.microsoft.com/en-us/windows/bb980924.aspx) after the installation of Visual C++ 2010 Express? Perhaps this should be added to the Freeswitch windows installation instructions page: http://wiki.freeswitch.org/wiki/Installation_for_Windows Q3) Should I expect the http://latest.freeswitch.org/ version of freeswitch to Build first time? Has this been tested? Q4) Should I simply use the 1.0.6 version with Visual C++ 2008 Express and follow the Freeswitch book word for word? This seems a reliable path, but I am a 'C' developer myself and would like to start out with a more up-to-date dev. environment and a version of freeswitch that is closer to the current version. Q5) Can someone make comments on the Build errors that are inside the attached file. Obviously I could go through and debug each build error, however I feel it best to have my questions answered above to avoid wasting time. Please note. I can happily start again and go back in time to the point prior to the installation of Visual C++ 2010 Express, since I am running a ESXi Virtual Machine. All I aiming for is a clean setup of FreeSWITCH under XP for testing and developing purposes (this is not to run in a production environment). I would like to be as up-to-date as possible in order to progress quickly (obviously I will install GIT/TortoiseGIT etc.. to make my dev. environment more integrated once I have a working base version of Freeswitch). Thanks in advance, Andrew Keil

recvEvent causes zombies process
by Ejay Greeves 29 Mar '11

29 Mar '11

I am wanting to code an inbound event program. In order to see why I am getting zombie processes I stripped out all my code and used the minimum skeletcon code to do a test. con = ESL::ESLconnection.new('127.0.0.1', '8021', 'ClueCon')con.events("plain", "CHANNEL_HANGUP_COMPLETE") loop do event = con.recvEvent pid = fork do end Process.detach(pid) end This code does nothing but wait for an incoming event, creates an fork then detach however it still produces a defunct process. I think con.recvEvent is the cause?

How to set PIN after conference created?
by Duncan Pierce 29 Mar '11

29 Mar '11

Hi everyone, I'm new to FreeSWITCH. I've managed to set up many features quite easily but I'm struggling with mod_conference. I want to allow a user to create a conference and set its PIN by dialling a special number 81<conference_number>*<pin>: <extension name="initiate_conference"> <condition field="destination_number" expression="^81(\d*)\*(\d*)$"> <action application="log" data="INFO Creating conference $1 with PIN $2"/> <action application="answer"/> <action application="conference" data="$1@default+$2"/> </condition> </extension> Other users can dial into the same conference using a different access number, but are challenged for the PIN set by the first user: <extension name="join_conference"> <condition field="destination_number" expression="^82(\d*)$"> <action application="answer"/> <action application="conference" data="$1"/> </condition> </extension> There is no <param name="pin" ...> set in <configuration name="conference.conf"><profiles><profile name="default">. I was expecting <action application="conference" data="$1@default+$2"/> to create the conference and set its PIN, so that a subsequent <action application="conference" data="$1"/> would be challenged to provide the same PIN. Instead what happens is the first caller has the required PIN set for their call, but the second caller is not challenged to provide the PIN at all. Looking at the code in mod_conference.c on git checkout v1.0.6 I see there only 2 ways conference->pin can be set: via <param name="pin" .../> in the profile or via API 'conference $1 pin $2'. I was expecting there would be a third way: assigning conference->pin = dpin when creating a new conference. Although I find this a bit confusing it could be by design. I tried using the API to set the PIN after the conference has been created but I lack the knowledge to do this successfully. I've tried: * <action application="set" data="result=${conference($1 pin $2)}"/> after <action application="conference" data="$1@default+$2"/> - no actions execute after the <action application="conference"> * <action application="set" data="result=${conference($1 pin $2)}"/> before <action application="conference" data="$1@default+$2"/> - unsurprisingly, it reports conference not found * <action application="export" data="nolocal:api_on_answer=conference $1 pin $2"/> - appears not to execute but it's difficult to be sure in this case Thanks in advance for any help you can provide! Best regards, Duncan
