[recon-devel] Capture conversation audio in file

[Spiridon Dimopoulos]

Hello,

I am trying to capture the audio stream during a conversation, in either a file or a buffer. I have found that in every remoteParticipant the sipXtapi ConnectionID is saved and also the MediaInterface pointer. By accessing those 2 I am calling the RecordChannelAudio like this:

participant->getMediaInterface()->getInterface()->recordChannelAudio(participant->getMediaConnectionId(),"/tmp/test.wav");

Confirmation from sipXtapi is OK that starts recording (although verifying the connectionID as -1 and not the ConnectionID from participant). The wav file is created and the length is quite close to the actual call duration that the participant is attending. But the audio file is total silence. Do I have to make any adjustments to the flowgraph to connect the recorder with the channel and capture the audio?? Maybe I have to modify the mixer weights somewhere?

Using version 1.9.8 of reciprocate and sipXtapi 3.3.0 test17 library package for Ubuntu.

Thank you,
Spiros

I believe you will need to setup the Mix as you have suggested. It's been
awhile since I've look at recon, so I can't guide you off the top of my
head very well right now. :)

You can try the sipXtapi mailing list as well, since this seems more
specific to that component. http://sipxtapi.sipfoundry.org/wiki/SipXtapi
