Accessing audio samples from linphone

I'm using linphone开发者_如何转开发c (without gtk interface, only command line) in Linux and I want to access incoming and outgoing sound samples, but I don't know what file should I edit to access them. Can anybody give me a clue, please?


Assuming the outgoing and incoming sound samples are related to a call e.g. you are typing linphonec> call sip:usernumber@someproxy.net.

The call stack of the function is:

lpc_cmd_call from linphone-version/console/commands.c
linphone_core_invite_with_params from linphone-version/coreapi/linphonecore.c
linphone_core_invite_address_with_params from linphone-version/coreapi/linphonecore.c
linphone_core_start_invite from linphone-version/coreapi/linphonecore.c
linphone_call_init_media_streams from linphone-version/coreapi/linphonecall.c
audio_stream_new from from linphone-version/mediastreamer2/src/audiostream.c

Media stream is initialised on the host and can be accessed using mediastreamer2 API

In terms of accepting a call see the following call stack:

linphone_core_accept_call from linphone-version/coreapi/linphonecore.c
linphone_core_update_streams from linphone-version/coreapi/callbacks.c
linphone_call_start_media_streams from  linphone-version/coreapi/linphonecall.c
linphone_call_start_audio_stream from  linphone-version/coreapi/linphonecall.c
audio_stream_start_full from linphone-version/mediastreamer2/src/audiostream.c

Media stream is initialised on the client and can be accessed using mediastreamer2 API.

mediastreamer2 API documentation is avaliable here

linphone Source Code is avaliable here or here
