一、

live555\testProgs\testRTSPClient.cpp 测试rtsp命令和数据接收：

1.发送并处理Describe消息

rtspClient->sendDescribeCommand(continueAfterDESCRIBE);

2.发送并处理Setup消息

rtspClient->sendSetupCommand(*scs.subsession, continueAfterSETUP);

3. 创建sink，准备接收媒体数据

scs.subsession->sink =DummySink::createNew(env, *scs.subsession, rtspClient->url());

4.开始播放

scs.subsession->sink->startPlaying(*(scs.subsession->readSource()),

subsessionAfterPlaying, scs.subsession);

5.获取媒体数据

Poll 模式调用getNexFrame获取媒体数据

fSource->getNextFrame(fReceiveBuffer, DUMMY_SINK_RECEIVE_BUFFER_SIZE,

afterGettingFrame,this,

onSourceClosure, this);

VLC 的live555插件也是使用poll模式调用getNexFame 获取媒体数据
