android上使用mp4v2合成h264+aac，写入音频数据后打不开视频文件

Question

我在android上写了一个视频录制程序，录制时把视频、音频数据放在两个队列里，并开启两个线程去读取数据，写到sd卡中。现在的问题是，如果只写入h264，则视频播放正常（使用videoView，虽然没有声音）；但如果同时写入了音频数据，则打不开视频文件。请问可能是什么原因才会造成这种结果呢？

打包h264+aac的代码如下：

 //写视频数据
BOOL WriteVideoData(RECORD_PARAM *struRecordParam, char* pVideoData, int nSize, int iFrameRate, int iType, long lTimestemp){

    BOOL bResult = FALSE;
    if(struRecordParam==NULL || struRecordParam->mp4FileHandle<=0 || struRecordParam->isOpen==FALSE) return FALSE;

    if (nSize==0) {//写空帧
        if (!MP4WriteSample(struRecordParam->mp4FileHandle,
            struRecordParam->videoId,
            (const uint8_t*)pVideoData,
            nSize,
            lTimestemp,
            0,
            true)) {

            return FALSE;
        }

        return TRUE;
    }

    if ((pVideoData[4]&0x1f) == 7) {

        NSLOGE("writeVideoFrame: if 7");

        if (struRecordParam->hasSPS) {
            return FALSE;
        }

        NSLOGE("to MP4AddH264VideoTrack ");
        struRecordParam->videoId = MP4AddH264VideoTrack(struRecordParam->mp4FileHandle,
                struRecordParam->nVideoTimeScale,
                (struRecordParam->nVideoTimeScale/struRecordParam->nVideoFrameRate),
                struRecordParam->nVideoWidth,
                struRecordParam->nVideoHeight,
                pVideoData[5],
                pVideoData[6],
                pVideoData[7],
                3);

        if (struRecordParam->videoId == MP4_INVALID_TRACK_ID) {
            return FALSE;
        }

        MP4SetVideoProfileLevel(struRecordParam->mp4FileHandle, 0x7F);

        MP4AddH264SequenceParameterSet(struRecordParam->mp4FileHandle,
                struRecordParam->videoId,
                (const uint8_t*)(pVideoData+4),
                nSize-4);
        struRecordParam->hasSPS = TRUE;
        NSLOGE("MP4AddH264VideoTrack ok");

    } else if ((pVideoData[4]&0x1f) == 8) {
        NSLOGE("writeVideoFrame: if 8");

        if (struRecordParam->hasPPS) {
          return FALSE;
        }

        MP4AddH264PictureParameterSet(struRecordParam->mp4FileHandle,
                struRecordParam->videoId,

                nSize-4);
        struRecordParam->hasPPS = TRUE;

    } else {
        NSLOGE("writeVideoFrame: if else");

        pVideoData[0] = (nSize-4) >> 24;
        pVideoData[1] = (nSize-4) >> 16;
        pVideoData[2] = (nSize-4) >> 8;
        pVideoData[3] = (nSize-4) & 0xff;

        if (!MP4WriteSample(struRecordParam->mp4FileHandle,
                struRecordParam->videoId,
                (const uint8_t*)(pVideoData),
                nSize,
                MP4_INVALID_DURATION,
                0,
                true)) {

            return FALSE;
        }
    }


    return TRUE;
 }

//写音频数据
BOOL WriteAudioData(RECORD_PARAM *struRecordParam, char* pAudioData, int nSize, long lTimestemp){

    if(struRecordParam==NULL || struRecordParam->mp4FileHandle<=0 || struRecordParam->isOpen==FALSE) return FALSE;

            return FALSE;
