HarmonyOS OH_AudioStreamBuilder_GenerateCapturer失败

OH_AudioStreamBuilder *builder = nullptr;
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);
audioCapturer_ = nullptr;
OH_AudioStream_Result result = OH_AudioStreamBuilder_GenerateCapturer(builder, &audioCapturer_);
IRTC_LOG_DEBUG("%{public}d", result);
if(audioCapturer_){
  OH_AudioCapturer_Start(audioCapturer_);
}

OH_AudioStreamBuilder_GenerateCapturer返回值为AUDIOSTREAM_ERROR_INVALID_PARAM，但是代码是从官方api文档里拷贝下来的。
