一、准备工作
搭建本地rtmp服务：
https://www.cnblogs.com/doudouyoutang/p/6602430.html
获取使用到的库，openssl 和 librtmp
参考：

https://github.com/x2on/OpenSSL-for-iPhone
也可以从我的工程中直接拿
二、代码编写
利用librtmp中的RTMP_Read函数，直接读取到的就是FLV流，然后写入文件，就可以正常播放了。
void RtmpStreamDumper::startDump()
{
int readBytes = 0;
bool bLiveStream = true;
int bufsize = 1024*1024*10;
long countbufsize = 0;
char *buf = (char*)calloc(sizeof(char), bufsize);
char *path = (char*)calloc(sizeof(char), this->rtmp_rsource_url.size() + 1);
strcpy(path, this->rtmp_rsource_url.c_str());
RTMP_LogPrintf("Start Dump To %s", this->dump_flv_path.c_str());
RTMP *rtmp = RTMP_Alloc();
RTMP_Init(rtmp);
rtmp->Link.timeout=10;
if(!RTMP_SetupURL(rtmp, path))
{
RTMP_Log(RTMP_LOGERROR,"SetupURL Err\n");
RTMP_Free(rtmp);
return;
}
if (bLiveStream){
rtmp->Link.lFlags|=RTMP_LF_LIVE;
}
RTMP_SetBufferMS(rtmp, 3600*1000);
if(!RTMP_Connect(rtmp,NULL)){
RTMP_Log(RTMP_LOGERROR,"Connect Err\n");
RTMP_Free(rtmp);
return ;
}
if(!RTMP_ConnectStream(rtmp,0)){
RTMP_Log(RTMP_LOGERROR,"ConnectStream Err\n");
RTMP_Close(rtmp);
RTMP_Free(rtmp);
return ;
}
while((readBytes = RTMP_Read(rtmp,buf,bufsize))){
this->dumpBytesToFlv((const unsigned char *)buf, readBytes);
countbufsize += readBytes;
RTMP_LogPrintf("Receive: %5dByte, Total: %5.2fkB\n",readBytes,countbufsize*1.0/1024);
}
if(buf){
free(buf);
}
if(rtmp){
RTMP_Close(rtmp);
RTMP_Free(rtmp);
rtmp=NULL;
}
}
三、执行效果
四、已经封装为可执行文件
std::cout<<"use example :RtmpDumper [rtmp_live_url] [flv_save_path(default to excute folder)]"<<std::endl;
std::string url((argc > 1)?argv[1]:"");
std::string path((argc > 2)?argv[2]:"");
RtmpStreamDumper *dp = new RtmpStreamDumper(url, path);
dp->startDump();
return 0;
使用方法
RtmpDumper rtmp://localhost:1935/myapp/room
五、代码

Dump Rtmp Stream To FLV File （从Rtmp流保存为FLV文件）
