hi3507/hi3515交叉编译live555

 

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闭嘴

 

2、放到linux目录下解压:

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

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在新闻报道奋斗)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 WAV 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

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。

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

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
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 =


再次生成Makefile并编译

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
