ios - 如何在 ios 中使用 pjsip 进行通话录音？

Question

我制作了 VOIP 应用程序。现在我需要实现通话录音功能。我正在使用以下功能进行通话录音:

+(NSString *)startRecording:(int)callid userfilename:(NSString 
*)filename
{

pjsua_recorder_id recorder_id;

pj_status_t status;

NSArray       *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString  *documentsDirectory = [paths objectAtIndex:0];
NSString *strPath = [NSString stringWithFormat:@"%@/%@", documentsDirectory,filename];

pj_str_t fileName = pj_str([strPath UTF8String]);
status = pjsua_recorder_create(&fileName, 0, NULL, 0, 0, &recorder_id);
NSLog(@"status issss-->%d",status);

pjsua_call_info call_info;

status = pjsua_recorder_create(&fileName, 0, NULL, -1, 0, &app_config.rec_id);
isRecordingStarted = 1;
if (status != PJ_SUCCESS)
{
    pjsua_perror(THIS_FILE, "error dll_startAudioCapture from pjsua_recorder_create", status);
}
else
{
    app_config.rec_port = pjsua_recorder_get_conf_port(app_config.rec_id);
    PJ_LOG(5, (THIS_FILE, "dll_startAudioCapture recId=%d confPort=%d", app_config.rec_id, app_config.rec_port));
    /* connect sound port to recorder port */
    status = pjmedia_conf_connect_port(pjsua_var.mconf, 0, app_config.rec_port, 0);
    if (status != PJ_SUCCESS)
    {
        pjsua_perror(THIS_FILE, "error dll_startAudioCapture edia_conf_connect_port snd->recport", status);
    }
    /* connect caller's port to recorder port */
    pjsua_call_get_info(0, &call_info); //callid
    status = pjmedia_conf_connect_port(pjsua_var.mconf, call_info.conf_slot, app_config.rec_port, 0);
    if (status != PJ_SUCCESS)
    {
        //                pjsua_perror(THIS_FILE, @"error dll_startAudioCapture pjmedia_conf_connect_port caller->recport", status);
    }
    //boost callTaker's and caller audio levels as configured
    if ((status = pjmedia_conf_adjust_rx_level(pjsua_var.mconf, pjsua_var.recorder[app_config.rec_id].slot,0)) == PJ_SUCCESS)
    {
        //                PJ_LOG(5, (THIS_FILE, "dll_startAudioCapture pjmedia_conf_adjust_rx_level by %d", g_audCapClientBoost));
    }
    else
    {
        pjsua_perror(THIS_FILE, "Error dll_startAudioCapture pjmedia_conf_adjust_rx_level", status);
    }
    if ((status = pjmedia_conf_adjust_tx_level(pjsua_var.mconf,pjsua_var.recorder[app_config.rec_id].slot,0)) == PJ_SUCCESS)
    {
        //                PJ_LOG(5, (THIS_FILE, "dll_startAudioCapture pjmedia_conf_adjust_tx_level by %d", g_audCapServerBoost));
    }
    else
    {
        pjsua_perror(THIS_FILE, "Error dll_startAudioCapture pjmedia_conf_adjust_tx_level", status);
    }
}
NSLog(@"str path is====>%@",strPath);
return strPath;
}

停止录音:

+(void)stopRecording:(int)callid
{
    //    pjsua_call_info call_info;
   //    pjsua_call_get_info(callid, &call_info);
   if(app_config.rec_id != 0)
   {
    pj_status_t status = pjsua_recorder_destroy(app_config.rec_id);
    NSLog(@"sttaus iiisss ----> %d",status);
    NSLog(@"recording id is---->%d",app_config.rec_id);
    isRecordingStarted = 0;

  }

}

上面的代码非常适合 3 次录音。当我开始第 4 次录音时，出现错误 “error dll_startAudioCapture from pjsua_recorder_create”

所以任何人都有使用 pjsip 进行通话录音的解决方案，请帮助我。

谢谢。

+(NSString *)startRecording:(int)callid userfilename:(NSString 
  *)filename
 {
pjsua_recorder_id recorder_id;

pj_status_t status;

NSArray       *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);

pj_str_t fileName = pj_str([strPath UTF8String]);
status = pjsua_recorder_create(&fileName, 0, NULL, -1, 0, &recorder_id);
NSLog(@"status issss-->%d",status);

[[NSUserDefaults standardUserDefaults] setInteger:recorder_id forKey:@"recording_id"];
[[NSUserDefaults standardUserDefaults] synchronize];

pjsua_call_info call_info;

NSLog(@"recordder id id--->%d",recorder_id);
NSLog(@"recording is for start recording is--->%d",app_config.rec_id);

//status = pjsua_recorder_create(&fileName, 0, NULL, -1, 0, &app_config.rec_id);
isRecordingStarted = 1;
if (status != PJ_SUCCESS)
{
    pjsua_perror(THIS_FILE, "error dll_startAudioCapture from pjsua_recorder_create", status);
}
else
{
    //        app_config.rec_port = pjsua_recorder_get_conf_port(app_config.rec_id);

    app_config.rec_port = pjsua_recorder_get_conf_port(recorder_id);
    PJ_LOG(5, (THIS_FILE, "dll_startAudioCapture recId=%d confPort=%d", app_config.rec_id, app_config.rec_port));
    /* connect sound port to recorder port */
    status = pjmedia_conf_connect_port(pjsua_var.mconf, 0, app_config.rec_port, 0);
    if (status != PJ_SUCCESS)
    {
        pjsua_perror(THIS_FILE, "error dll_startAudioCapture edia_conf_connect_port snd->recport", status);
    }
    /* connect caller's port to recorder port */
    pjsua_call_get_info(0, &call_info); //callid

    if (status != PJ_SUCCESS)
    {
        //                pjsua_perror(THIS_FILE, @"error dll_startAudioCapture pjmedia_conf_connect_port caller->recport", status);
    }
    //boost callTaker's and caller audio levels as configured
    if ((status = pjmedia_conf_adjust_rx_level(pjsua_var.mconf, pjsua_var.recorder[app_config.rec_id].slot,0)) == PJ_SUCCESS)
    {
        //                PJ_LOG(5, (THIS_FILE, "dll_startAudioCapture pjmedia_conf_adjust_rx_level by %d", g_audCapClientBoost));
    }
    else
    {
        pjsua_perror(THIS_FILE, "Error dll_startAudioCapture pjmedia_conf_adjust_rx_level", status);

    }
    else
    {
        pjsua_perror(THIS_FILE, "Error dll_startAudioCapture pjmedia_conf_adjust_tx_level", status);
    }
}

NSLog(@"str path is====>%@",strPath);
return strPath;
}

+(void)stopRecording:(int)callid
{
//    pjsua_call_info call_info;
//    pjsua_call_get_info(callid, &call_info);

NSInteger int_recording_id = [[NSUserDefaults standardUserDefaults] integerForKey:@"recording_id"];

pjsua_recorder_id recorder_id = int_recording_id;

//    if(recorder_id != 0)
//    {

pj_status_t status = pjsua_recorder_destroy(recorder_id);
NSLog(@"sttaus iiisss ----> %d",status);
NSLog(@"recording id is---->%d",recorder_id);
isRecordingStarted = 0;


//  }
}

请替换上面的方法。我在开始录制时将 recording_id 存储在用户默认值中。停止时，录制从用户默认值中获取值，然后停止该 recording_id 录制。

谢谢。
