live555 交叉编译移植到海思开发板

本文章参考了。http://blog.csdn.net/lawishere/article/details/8182952，写了hi3518的配置说明。特此感谢

https://blog.csdn.net/sunxiaopengsun/article/details/79175408

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：

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文件放在当前目录下

执行mediaServer目录下的live555MediaServer服务器原型

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-hisiv100nptl-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.*

因此我们复制一个config.hi3518，命令：cp config.armlinux config.hi3518

CROSS_COMPILE?=     arm-hisiv100nptl-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 =

然后与在PC上编译一样，进行编译。

root@kubuntu:/home/frank/live# ./genMakefiles hi3518
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。上面那段是已经去掉的

 再次生成Makefile并编译

root@kubuntu:/home/frank/live# ./genMakefiles hi3518
root@kubuntu:/home/frank/live# make

编译成功！

5 移植到海思开发板上

将mediaServer的live555MediaServer(你可以试一下，在linux系统中打开这个是出错误的)，通过nfs挂载到开发板上执行。运行后会出现

LIVE555 Media Server-Test frank
        version 0.84 (LIVE555 Streaming Media library version 2014.10.07).
Play streams from this server using the URL
        rtsp://0.0.0.0/<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
        ".265" => a H.265 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
        ".ogg" or ".ogv" or ".opus" => an Ogg audio and/or video file
        ".ts" => a MPEG Transport Stream file
                (a ".tsx" index file - if present - provides server 'trick play)
        ".vob" => a VOB (MPEG-2 video with AC-3 audio) file
        ".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 80 for optional RTSP-over-HTTP tunneling, or for HT

测试的时候会发现RTSP的地址是0.0.0.0；

在nfs挂载的时候，已经用ifconfig eth0 192.168.0.166 将板子的IP地址设为了192.168.0.166 ，为什么还是0 呢

需要用到route add default gw 192.168.0.1,这个192.168.0.1是网关的IP地址，也就是你的路由器的IP地址，命令意思的是添加一条默认网关命令，将所有的数据包都转发到192.168.0.1；注意开发板上是运行./live555MediaServer,发现时没有端口号的，直接rtsp://192.168.0.166 就可以看到想要的结果，预祝成功。

如何在hisi编译好的live555版本基础上修改成g++编译？

将 所有工程中的CROSS_COMPILE变量设置为空即可。
