技术点：
1、live555实时数据处理(难点)
2、G711编码实现(同时实现AAC编码)
3、音视频时间戳的了解(后期做同步需要深入研究)
4、VLC的日志调试
//-------------------------------------------------------------------------------------------------------------------------------------//
遇到的难点：
1、live555通过队列取G711 ALAW编码数据，数据发生变化导致VLC播放有杂音
解决方案：
查起来麻烦，摈弃队列使用缓存拷贝，VLC播放效果明显变好
2、G711 ALAW编码数据正常，live555推流结束后，VLC才播放开始几包声音数据
原因：VLC播放声音原因时间戳
解决方案：在AudioFrameLiveSource::doGetNextFrame()中添加gettimeofday(&fPresentationTime,NULL);
3、单独视频流单独音频流VLC都播放正常。两路流一起推，VLC黑屏声音正常
原因：live555单线程机制，AudioFrameLiveSource::doGetNextFrame()和VideoFrameLiveSource::doGetNextFrame()两个不能都有阻塞操作，出现上述现象是因为，AudiodoGetNextFrame获取实时数据频率高且有阻塞等待现象，导致视频VideodoGetNextFrame也无法处理数据。
解决方案：目前机制AudiodoGetNextFrame获取实时数据失败不做等待且memcpy(fTo,audiodata,0)，VideodoGetNextFrame仍阻塞获取实时数据。效果不错！
