HarmonyOS 鸿蒙Next 音频采集，回调不被调用

HarmonyOS 鸿蒙Next 音频采集，回调不被调用 回调函数：

int32_t MyCaptureOnReadData(OH_AudioCapturer *capturer, void *userData, void *buffer, int32_t length) {
    // 从buffer中取出length长度的录音数据
    IRTC_LOG_DEBUG();
    return 0;
}

// 自定义音频流事件函数
int32_t MyCaptureOnStreamEvent(OH_AudioCapturer *capturer, void *userData, OH_AudioStream_Event event) {
    // 根据event表示的音频流事件信息，更新播放器状态和界面
    IRTC_LOG_DEBUG();
    return 0;
}

// 自定义音频中断事件函数
int32_t MyCaptureOnInterruptEvent(OH_AudioCapturer *capturer, void *userData, OH_AudioInterrupt_ForceType type, OH_AudioInterrupt_Hint hint) {
    // 根据type和hint表示的音频中断信息，更新录制器状态和界面
    IRTC_LOG_DEBUG();
    return 0;
}

// 自定义异常回调函数
int32_t MyCaptureOnError(OH_AudioCapturer *capturer, void *userData, OH_AudioStream_Result error) {
    // 根据error表示的音频异常信息，做出相应的处理
    IRTC_LOG_DEBUG();
    return 0;
}

开启采集代码

OH_AudioStreamBuilder *builder;
OH_AudioStreamBuilder_Create(&builder, AUDIOSTREAM_TYPE_CAPTURER);
// 设置音频采样率
OH_AudioStreamBuilder_SetSamplingRate(builder, 48000);
// 设置音频声道
OH_AudioStreamBuilder_SetChannelCount(builder, 2);
// 设置音频采样格式
OH_AudioStreamBuilder_SetSampleFormat(builder, AUDIOSTREAM_SAMPLE_S16LE);
// 设置音频流的编码类型
OH_AudioStreamBuilder_SetEncodingType(builder, AUDIOSTREAM_ENCODING_TYPE_RAW);
// 设置输入音频流的工作场景
OH_AudioStreamBuilder_SetCapturerInfo(builder, AUDIOSTREAM_SOURCE_TYPE_MIC);
OH_AudioCapturer_Callbacks callbacks;
// 配置回调函数
callbacks.OH_AudioCapturer_OnReadData = MyCaptureOnReadData;
callbacks.OH_AudioCapturer_OnStreamEvent = MyCaptureOnStreamEvent;
callbacks.OH_AudioCapturer_OnInterruptEvent = MyCaptureOnInterruptEvent;
callbacks.OH_AudioCapturer_OnError = MyCaptureOnError;
OH_AudioStreamBuilder_SetCapturerCallback(builder, callbacks, nullptr);
OH_AudioStreamBuilder_GenerateCapturer(builder, &audioCapturer_);
OH_AudioCapturer_Start(audioCapturer_);

MyCaptureOnReadData函数不会被回调
