receiver.cpp

简单的rtp流媒体文件发送和接收程序,c语言实现。

#include <stdio.h>
#include "rtpsession.h"
#include "rtppacket.h"

// 错误处理函数
void checkerror(int err)
{
  if (err < 0) {
    char* errstr = RTPGetErrorString(err);
    printf("Error:%s\n", errstr);
    exit(-1);
  }
}

int main(int argc, char** argv)
{
  RTPSession sess;
  int localport;
  int status;

  if (argc != 2) {
    printf("Usage: ./sender localport\n");
    return -1;
  }

   // 获得用户指定的端口号
  localport = atoi(argv[1]);

  // 创建RTP会话
  status = sess.Create(localport);
  checkerror(status);

  do {
    // 接受RTP数据
    status = sess.PollData();
	// 检索RTP数据源
    if (sess.GotoFirstSourceWithData()) {
      do {
        RTPPacket* packet;
        // 获取RTP数据报
        while ((packet = sess.GetNextPacket()) != NULL) {

          // 删除RTP数据报
          delete packet;
        }
      } while (sess.GotoNextSourceWithData());
    }
  } while(1);

  return 0;
