live555 移植

转自：http://blog.csdn.net/lawishere/article/details/8182952

Live555 是一个为跨平台的C++开源项目，它实现了RTP/RTCP、RTSP、SIP等的支持。并且相对于其他的流媒体服务器是完全开源并且免费的。

废话不多说，下面开始。



1、首先到它的主页下载一个源码包：

http://www.live555.com/liveMedia/public/

我下载的是latest的，具体什么版本还真不清楚




2、放到linux目录下解压：

[html] view
plaincopyprint?

root@kubuntu:/home/frank tar zxvf live555-latest.tar.gz

root@kubuntu:/home/frank# cd live

root@kubuntu:/home/frank/live#



3、首先尝试在PC的Linux上编译：

区别于传统的源码包，不是传统的配置方式，而是通过genMakefiles配对目录下的config.*文件生成Makefile

[html] view
plaincopyprint?

root@kubuntu:/home/frank/live# ./genMakefiles linux

root@kubuntu:/home/frank/live# make

编译很顺利，然后上网找一个*.264文件（常见的就是那个test.264在新闻报道

）放在当前目录下

执行mediaServer目录下的live555MediaServer服务器原型

root@kubuntu:/home/frank/live# ./mediaServer/live555MediaServer

LIVE555 Media Server

version 0.75 (LIVE555 Streaming Media library version 2012.11.08).

Play streams from this server using the URL

rtsp://192.168.1.41:8554/<filename>

where <filename> is a file present in the current directory.

Each file's type is inferred from its name suffix:

".264" => a H.264 Video Elementary Stream file

".aac" => an AAC Audio (ADTS format) file

".ac3" => an AC-3 Audio file

".amr" => an AMR Audio file

".dv" => a DV Video file

".m4e" => a MPEG-4 Video Elementary Stream file

".mkv" => a Matroska audio+video+(optional)subtitles file

".mp3" => a MPEG-1 or 2 Audio file

".mpg" => a MPEG-1 or 2 Program Stream (audio+video) file

".ts" => a MPEG Transport Stream file

(a ".tsx" index file - if present - provides server 'trick play' support)

".wav" => a W*** Audio file

".webm" => a WebM audio(Vorbis)+video(VP8) file

See http://www.live555.com/mediaServer/ for additional documentation.

(We use port 8080 for optional RTSP-over-HTTP tunneling, or for HTTP live streaming (for indexed Transport Stream files only).)

通过VLC可以点播rtsp://192.168.1.41:8554/test.264视频，

（注意：test.264所在的目录要和live555MediaServer执行目录相一致，若test.264放在live目录下，则需要在live目录下执行./mediaServer/live555MediaServer）



4、交叉编译

编译器arm-hismall-linux-gcc/arm-hismall-linux-g++

同理如果通过genMakefiles生成交叉编译的Makefile，我们需要一个对应的config.*

因此我们创建一个config.hi3507，内容可以参考config.armlinux

[html] view
plaincopyprint?

root@kubuntu:/home/frank/live# cat config.hi3507

CROSS_COMPILE?= arm-hismall-linux-

COMPILE_OPTS = $(INCLUDES) -I. -O2 -DSOCKLEN_T=socklen_t -DNO_SSTREAM=1 -D_LARGEFILE_SOURCE=1 -D_FILE_OFFSET_BITS=64

C = c

C_COMPILER = $(CROSS_COMPILE)gcc

C_FLAGS = $(COMPILE_OPTS)

CPP = cpp

CPLUSPLUS_COMPILER = $(CROSS_COMPILE)g++

CPLUSPLUS_FLAGS = $(COMPILE_OPTS) -Wall -DBSD=1

OBJ = o

LINK = $(CROSS_COMPILE)g++ -o

LINK_OPTS =

CONSOLE_LINK_OPTS = $(LINK_OPTS)

LIBRARY_LINK = $(CROSS_COMPILE)ar cr

LIBRARY_LINK_OPTS = $(LINK_OPTS)

LIB_SUFFIX = a

LIBS_FOR_CONSOLE_APPLICATION =

LIBS_FOR_GUI_APPLICATION =

EXE =



然后与在PC上编译一样，进行编译。

[html] view
plaincopyprint?

root@kubuntu:/home/frank/live# ./genMakefiles hi3507

root@kubuntu:/home/frank/live# make clean;make

这里要记得先make clean，否则因为之前在PC上编译的目标文件没清楚会导致链接失败。

编译时会产生一个错误

[html] view
plaincopyprint?

In file included from MPEG4GenericRTPSink.cpp:22:

include/Locale.hh:47:123: xlocale.h: No such file or directory

In file included from MPEG4GenericRTPSink.cpp:22:

include/Locale.hh:62: error: `locale_t' does not name a type

make[1]: *** [MPEG4GenericRTPSink.o] Error 1

make[1]: Leaving directory `/home/frank/live/liveMedia'

make: *** [all] Error 2

这个是由于海思使用的是uClinux，并没有xlocale.h这个头文件，

而live555内部的一个locale模块调用了（见liveMeida/locale.hh），因此通过编译选项把他去掉。

修改config.hi3507，在编译选项上加入-DLOCALE_NOT_USED把此模块去掉。

CROSS_COMPILE?= arm-hismall-linux-

COMPILE_OPTS = $(INCLUDES) -I. -O2 -DSOCKLEN_T=socklen_t -DNO_SSTREAM=1 -D_LARGEFILE_SOURCE=1 -D_FILE_OFFSET_BITS=64

C = c

C_COMPILER = $(CROSS_COMPILE)gcc

C_FLAGS = $(COMPILE_OPTS)

CPP = cpp

CPLUSPLUS_COMPILER = $(CROSS_COMPILE)g++

CPLUSPLUS_FLAGS = $(COMPILE_OPTS) -Wall -DBSD=1 -DLOCALE_NOT_USED

LIBRARY_LINK = $(CROSS_COMPILE)ar cr

LIBRARY_LINK_OPTS = $(LINK_OPTS)

LIB_SUFFIX = a

LIBS_FOR_CONSOLE_APPLICATION =

LIBS_FOR_GUI_APPLICATION =

EXE =

再次生成Makefile并编译

[html] view
plaincopyprint?

root@kubuntu:/home/frank/live# ./genMakefiles hi3507

root@kubuntu:/home/frank/live# make

编译成功！

再按照上述方法把程序放到hi3507上运行测试
