I have tried the above methods to record and play during the call. I am not getting and beep at the receiver side. And the sound that I am playing is too low at the receiver side. Please look into the above code and help if I am making any mistakes.
I found that recorder id and callinfo.conf_port id is the same. and did not find any way to get the conf_slot in crated media_conf. Please help me I am stuck in this for days.
回答1:
You should use pjsua file player (pjsua_player*) and pjsua file recorder (pjsua_recorder*) instead.
Call pjsua_player_create()/pjsua_recorder_create() to create the player/recorder.
And to get the conf port, you can use pjsua_player_get_conf_port()/pjsua_recorder_get_conf_port().
You should be able to see the sample implementation on pjsua_app.c
