我已经尝试了上述方法在通话过程中进行录制和播放.我不会在接收方听到蜂鸣声.而且我正在播放的声音在接收器端太低.如果我有任何错误，请查看上面的代码并提供帮助.
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.
我发现记录器ID和callinfo.conf_port ID是相同的.并没有找到任何方法来将conf_slot获取到已创建的media_conf中.请帮我，我被困在这几天了.
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.
推荐答案
您应该改用pjsua文件播放器(pjsua_player *)和pjsua文件记录器(pjsua_recorder *).
You should use pjsua file player (pjsua_player*) and pjsua file recorder (pjsua_recorder*) instead.
调用pjsua_player_create()/pjsua_recorder_create()创建播放器/记录器.
Call pjsua_player_create()/pjsua_recorder_create() to create the player/recorder.
要获取conf端口，可以使用pjsua_player_get_conf_port()/pjsua_recorder_get_conf_port().
And to get the conf port, you can use pjsua_player_get_conf_port()/pjsua_recorder_get_conf_port().
您应该能够在pjsua_app.c上看到示例实现
You should be able to see the sample implementation on pjsua_app.c
