How to use sink write to write raw pcm data to an aac file，ultimate goal is use sink write to accept rgb data and pcm data into an overall video file

Question

I have been able to use sink write to read rgb32 data in a file to generate an mp4 video, please refer to the example on the official website https://learn.microsoft.com/zh-cn/windows/win32/medfound/tutorial--using-the-sink-writer-to-encode-video Now,I wanted a similar idea to write a pcm generated data to an aac or mp3 file, but there were some problems with the code:

HRESULT InitializeSinkWriter(IMFSinkWriter** ppWriter, DWORD* pStreamIndex)
{
    HRESULT hr = S_OK;
    *ppWriter = NULL;
    *pStreamIndex = NULL;

    DWORD streamIndex;
    IMFSinkWriter* pSinkWriter = NULL;
    IMFMediaType* pMediaTypeOut = NULL;
    IMFMediaType* pMediaTypeIn = NULL;


    // Set the input media type.
    if (SUCCEEDED(hr))
    {
        hr = MFCreateMediaType(&pMediaTypeIn);
    }
    if (SUCCEEDED(hr))
    {
        hr = pMediaTypeIn->SetGUID(MF_MT_MAJOR_TYPE, MFMediaType_Audio);
    }
    if (SUCCEEDED(hr))
    {
        hr = pMediaTypeIn->SetGUID(MF_MT_SUBTYPE, _recorderConf.audioInPutFormat);
    }
    if (SUCCEEDED(hr))
    {
        hr = pMediaTypeIn->SetUINT32(MF_MT_AUDIO_NUM_CHANNELS, _recorderConf.audioChannelNum);
    }
    if (SUCCEEDED(hr))
    {
        hr = pMediaTypeIn->SetUINT32(MF_MT_AUDIO_SAMPLES_PER_SECOND, _recorderConf.audioSamplePerSec);
    }
    if (SUCCEEDED(hr))
    {
        hr = pMediaTypeIn->SetUINT32(MF_MT_AUDIO_BITS_PER_SAMPLE, _recorderConf.audioBitPerSample);
    }
    if (SUCCEEDED(hr))
    {
        hr = pMediaTypeIn->SetUINT32(MF_MT_AUDIO_AVG_BYTES_PER_SECOND, _recorderConf.audioBytesPerSecond);
    }
    if (SUCCEEDED(hr))
    {
        hr = pMediaTypeIn->SetUINT32(MF_MT_ALL_SAMPLES_INDEPENDENT, _recorderConf.audioSampleIndependent);
    }
    if (SUCCEEDED(hr))
    {
        hr = pSinkWriter->SetInputMediaType(streamIndex, pMediaTypeIn, NULL);
    }

}

hr = pSinkWriter->SetInputMediaType(streamIndex, pMediaTypeIn, NULL); The hr return value for this line is: 0xc00d36b4 : The data specified for the media type is invalid, inconsistent, or not supported by this object。 I want to know what went wrong and what is the right way to do it
