运行ios的AppRTC，RtcEventLog问题

Question

我想在AppRTCMobile中添加一个接口，这个接口可以启动webrtc模块，以实现两部手机(局域网，已经知道IP地址和端口号)之间的语音通话，但是当我运行成功时，每次RtcEventLog调用该方法时都会出现异常，导致软件崩溃。我不知道呼叫呼叫是否合理。我真诚地感谢您在没有解决方案的情况下给予我的帮助。下面的源代码，请帮我找出问题所在。

    std::unique_ptr<RtcEventLog> event_log = webrtc::RtcEventLog::Create();
    webrtc::Call::Config callConfig = webrtc::Call::Config(event_log.get());
    callConfig.bitrate_config.max_bitrate_bps = 500*1000;
    callConfig.bitrate_config.min_bitrate_bps = 100*1000;
    callConfig.bitrate_config.start_bitrate_bps = 250*1000;

    webrtc::AudioState::Config audio_state_config = webrtc::AudioState::Config();
    cricket::VoEWrapper* g_voe  = nullptr;
    rtc::scoped_refptr<webrtc::AudioDecoderFactory> g_audioDecoderFactory;
    g_audioDecoderFactory = webrtc::CreateBuiltinAudioDecoderFactory();
    g_voe = new cricket::VoEWrapper();
    audio_state_config.audio_processing = webrtc::AudioProcessing::Create();
    g_voe->base()->Init(NULL,audio_state_config.audio_processing,g_audioDecoderFactory);
    audio_state_config.voice_engine = g_voe->engine();

    audio_state_config.audio_mixer = webrtc::AudioMixerImpl::Create();
    callConfig.audio_state = AudioState::Create(audio_state_config);
    std::unique_ptr<RtcEventLog> event_logg = webrtc::RtcEventLog::Create();
    callConfig.event_log = event_logg.get();
    g_call = webrtc::Call::Create(callConfig);



    g_audioSendTransport = new AudioLoopbackTransport();
    webrtc::AudioSendStream::Config config(g_audioSendTransport);
    g_audioSendChannelId = g_voe->base()->CreateChannel();
    config.voe_channel_id = g_audioSendChannelId;
    g_audioSendStream = g_call->CreateAudioSendStream(config);


    webrtc::AudioReceiveStream::Config AudioReceiveConfig;
    AudioReceiveConfig.decoder_factory = g_audioDecoderFactory;
    g_audioReceiveChannelId = g_voe->base()->CreateChannel();
    AudioReceiveConfig.voe_channel_id = g_audioReceiveChannelId;
    g_audioReceiveStream = g_call->CreateAudioReceiveStream(AudioReceiveConfig);

    g_audioSendStream->Start();
    g_audioReceiveStream->Start();

Here's a screenshot of the error that occurred when the crash occurred. Please tell me if you want to know more.

您的代码在event_log_->LogAudioPlayout()时崩溃...很明显，event_log_对象已经发布了。

由unique_ptr或scoped_refptr管理的对象在执行后会被释放，但这些对象在您的情况下可能仍会使用，这将导致崩溃问题。因此，将这些对象放在全局内存中或保留它们。
