二、编译

1、往文件 config.linux里的 COMPILE_OPTS 添加以下两个参数 -DNO_STD_LIB 和 -DNO_OPENSSL=1 ，修改后如下：

COMPILE_OPTS =		$(INCLUDES) -I/usr/local/include -I.  -O2 -DNO_STD_LIB -DNO_OPENSSL=1 -DSOCKLEN_T=socklen_t -D_LARGEFILE_SOURCE=1 -D_FILE_OFFSET_BITS=64
C =			c
C_COMPILER =		cc
C_FLAGS =		$(COMPILE_OPTS) $(CPPFLAGS) $(CFLAGS)
CPP =			cpp
CPLUSPLUS_COMPILER =	c++
CPLUSPLUS_FLAGS =	$(COMPILE_OPTS) -Wall -DBSD=1 $(CPPFLAGS) $(CXXFLAGS)
OBJ =			o
LINK =			c++ -o
LINK_OPTS =		-L. $(LDFLAGS)
CONSOLE_LINK_OPTS =	$(LINK_OPTS)
LIBRARY_LINK =		ar cr 
LIBRARY_LINK_OPTS =	
LIB_SUFFIX =			a
LIBS_FOR_CONSOLE_APPLICATION = -lssl -lcrypto
LIBS_FOR_GUI_APPLICATION =
EXE =

2、分别执行以下命令

./genMakefiles linux
make clean
make -j8
mkdir build
make install PREFIX=$PWD/build/***************************
以下用于交叉编译的，若是交叉编译不用输入上面的命令
****************************/
//创建脚本文件，并输入以下信息
#!/bin/bashLIVE555_DIR=`pwd`cd $LIVE555_DIRINSTALL_DIR=$LIVE555_DIR/build
mkdir -p $INSTALL_DIR#编译成静态库
export LDFLAGS="-static"#声明交叉编译器的路径
#export PATH=/opt/arm-gcc/bin/:$PATH./genMakefiles armlinux
make -j$(nproc) CROSS_COMPILE=aarch64-linux-gnu-make install PREFIX=$INSTALL_DIR CROSS_COMPILE=aarch64-linux-gnu-

三、搭建rtsp服务器

1、利用qt creator创建工程，在 *.pro 文件添加 live555 库和头文件的路径（注意库的顺序）

INCLUDEPATH *= /home/gui/live/build/include/liveMedia/
INCLUDEPATH *= /home/gui/live/build/include/BasicUsageEnvironment/
INCLUDEPATH *= /home/gui/live/build/include/groupsock
INCLUDEPATH *= /home/gui/live/build/include/UsageEnvironment/LIBS += -L/home/gui/live/build/lib/ -lliveMedia \-lBasicUsageEnvironment -lgroupsock -lUsageEnvironment

2、服务器代码实现如下（参考源码的testOnDemandRTSPServer.cpp文件例程）：

#include <QCoreApplication>#include "liveMedia.hh"
#include "BasicUsageEnvironment.hh"
#include "InputFile.hh"
#include "BasicHashTable.hh"
#include <GroupsockHelper.hh>
#include <iostream>static void announceURL(RTSPServer* rtspServer, ServerMediaSession* sms) {if (rtspServer == NULL || sms == NULL) return; // sanity checkUsageEnvironment& env = rtspServer->envir();env << "Play this stream using the URL ";if (weHaveAnIPv4Address(env)) {char* url = rtspServer->ipv4rtspURL(sms);env << "\"" << url << "\"";delete[] url;if (weHaveAnIPv6Address(env)) env << " or ";}if (weHaveAnIPv6Address(env)) {char* url = rtspServer->ipv6rtspURL(sms);env << "\"" << url << "\"";delete[] url;}env << "\n";
}static void announceStream(RTSPServer* rtspServer, ServerMediaSession* sms,char const* streamName, char const* inputFileName)
{UsageEnvironment& env = rtspServer->envir();env << "\n\"" << streamName << "\" stream, from the file \""<< inputFileName << "\"\n";announceURL(rtspServer, sms);
}int main(int argc, char *argv[])
{// Begin by setting up our usage environment:TaskScheduler* scheduler = BasicTaskScheduler::createNew();UsageEnvironment* env = BasicUsageEnvironment::createNew(*scheduler);//设置RTP数据的最大传输大小OutPacketBuffer::maxSize = 1000000;//创建一个rtsp的服务RTSPServer* rtspServer = RTSPServer::createNew(*env, 8554);if (rtspServer == NULL) {*env << "Failed to create RTSP server: " << env->getResultMsg() << "\n";exit(1);}char const* descriptionString= "Session streamed by \"LiveRTSPServer\"";Boolean reuseFirstSource = true;// A H.264 video elementary stream:{char const* streamName = "h264ESVideoTest";char const* inputFileName = "test.264";//hevc//创建一个会话ServerMediaSession* sms= ServerMediaSession::createNew(*env, streamName, streamName,descriptionString);//管理之前，需要先注册一个实例，实现里边所有的管理function,将来给rtsp服务调度。sms->addSubsession(H264VideoFileServerMediaSubsession::createNew(*env, inputFileName, reuseFirstSource));rtspServer->addServerMediaSession(sms);//将ServerMediaSession添加到rstp服务announceStream(rtspServer, sms, streamName, inputFileName);}// A MPEG-1 or 2 audio+video program stream:{char const* streamName = "mpeg1or2AudioVideoTest";char const* inputFileName = "test.mpg";// NOTE: This *must* be a Program Stream; not an Elementary StreamServerMediaSession* sms= ServerMediaSession::createNew(*env, streamName, streamName,descriptionString);MPEG1or2FileServerDemux* demux= MPEG1or2FileServerDemux::createNew(*env, inputFileName, reuseFirstSource);sms->addSubsession(demux->newVideoServerMediaSubsession(false));sms->addSubsession(demux->newAudioServerMediaSubsession());rtspServer->addServerMediaSession(sms);announceStream(rtspServer, sms, streamName, inputFileName);}//开始运行服务env->taskScheduler().doEventLoop(); // does not returnreturn 0;}
