AMRDeinterleaver H264BufferedPacket H264BufferedPacketFactory MPEG4GenericBufferedPacketFactory MPEG4VideoStreamParser MPEG4GenericBufferedPacket DummySink liveMedia库中Source，Sink以及 Filter等概念。Sink就是消费数据的对象，比如把接收到的数据存储到文件，这个文件就是一个Sink。 Source就是生产数据的对象，比如通过 RTP读取数据。数据流经过多个'source'和'sink's，下面是一个示例 File: E:\work\project\live555.mdl 17:13:29 2009年11月27日 Class Diagram: liveMedia / 类图
