封装音视频流为RTP包来网络传输

ios没有直接得api用来封装传输rtp，但是经常有用到得接收过来得音视频数据，经过X264处理转换便可以封装为Rtp包进行直接发送。大家可以看代码：

 

 1 #include "rtpsession.h"

 3 02. #include "rtppacket.h"

 5 03. #include "rtpudpv4transmitter.h"

 7 04. #include "rtpipv4address.h"

 9 05. #include "rtpsessionparams.h"

11 06. #include "rtperrors.h"
