完整成功-交叉编译mplayer，支持流媒体live555，总结出现错误和解决方法。

一、准备工作：

MPlayer-1.0rc1.tar.bz2   #MPlayer  source code  下载地址：MPlayer-1.0rc1.tar.bz2

libmad-0.15.1b.tar.gz      #解码库  下载地址：libmad-0.15.1b.tar.gz

live.2011.12.23.tar.gz      #live库的支持，流媒体功能必要 下载地址：live.2011.12.23.tar.gz

PS:好像只能使用这个版本的流媒体包，其他版本会导致，在编译mplayer时出现如下

demux_rtp_codec.cpp:(.text+0x61b): undefined reference to `operator new[](unsigned int)'
demux_rtp_codec.cpp:(.text+0x6f9): undefined reference to `operator delete[](void*)'
.......
.......
demux_rtp_codec.cpp:(.text+0xec0): undefined reference to `parseGeneralConfigStr(char const*, unsigned int&)'
collect2: ld returned 1 exit status
make: *** [mplayer] 错误 1

这是使用其他版本live555 版本包导致的

二、 安装工作：

1-解压libmad

tar -xvzf libmad-0.15.1b.tar.gz -C /opt/

进入libmad解压目录：cd libmad-0.15.1b/

./configure --enable-fpm=arm --host=arm-none-linux-gnueabi --disable-shared --disable-debugging --prefix=/opt/libmad-arm

make

make install

如果make的时候出现错误：

cc1: error: unrecognized command line option "-fforce-mem"

修改 Makefile 第129行 将 -fforce-mem 删除

vim Makefile

再执行make && make install

 

2-解压live库

tar -xvzf live.2011.12.23.tar.gz -C /usr/local/lib/

进入live解压目录 cd /usr/local/lib/live

vim config.armlinux

只修改其中部分如下:

CROSS_COMPILE=       arm-linux-

LIBRARY_LINK =     $(CROSS_COMPILE)ld -o

LIBRARY_LINK_OPTS =      $(LINK_OPTS) -r -Bstatic

保存后退出 

执行

./genMakefiles armlinux

make

好了接下来就是交叉编译mplayer了

3-解压mplayer库

tar -xvzf MPlayer-1.0rc1.tar.bz2 -C /opt/

进入mplayer解压目录 cd /opt/MPlayer-1.0rc1

创建一个脚本build.sh

mkdir build.sh

添加如下内容：

#!/bin/bash

./configure \
	--prefix=/opt/mplayer-arm \
	--cc=arm-linux-gcc \
	--host-cc=gcc \
	--enable-cross-compile \
	--target=arm-linux \
	--enable-linux-devfs \
	--disable-win32 \
	--disable-dvdread \
	--enable-fbdev \
	--disable-mencoder \
	--enable-libavcodec \
	--disable-liba52 \
	--disable-mp3lib \
	--enable-static \
	--disable-armv5te \
	--disable-iconv \
	--charset=noconv \
	--enable-mad \
	--enable-ossaudio \
	--enable-live \
	--with-livelibdir=/usr/local/lib/live \
	--with-extraincdir=/usr/local/arm/arm-2009q3/arm-none-linux-gnueabi/include:/opt/libmad/include \
	--with-extralibdir=/usr/local/arm/arm-2009q3/arm-none-linux-gnueabi/lib:/usr/local/arm/arm-2009q3/lib/:/opt/libmad/lib

注意链接路径的问题，修改为你自己的。

修改build.sh权限，再执行脚本：

chmod 777 build.sh

./build.sh

然后执行：

make 
make install

如果在执行make编译的过程中，会出现如下警告和错误

./version.sh `arm-linux-gcc -dumpversion`
arm-linux-gcc -c -Wdeclaration-after-statement -O4   -pipe -ffast-math -fomit-frame-pointer -D_REENTRANT -D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64 -I/usr/local/arm/arm-2009q3/arm-none-linux-gnueabi/include -I/opt/libmad/include -I/usr/include  -I/usr/local/lib/live/liveMedia/include              -I/usr/local/lib/live/UsageEnvironment/include              -I/usr/local/lib/live/BasicUsageEnvironment/include              -I/usr/local/lib/live/groupsock/include -I.  -I./libavutil -I./libavcodec -o mplayer.o mplayer.c
cc1: warning: include location "/usr/include" is unsafe for cross-compilation

                 from mplayer.c:6:

/usr/include/sys/sysmacros.h:80: warning: integer constant is too large for 'unsigned long' type
Makefile:277: recipe for target 'mplayer.o' failed
make: *** [mplayer.o] Error 1

则修改config.mak文件 

vim config.mak

将第22行中的 -I/usr/include 删除，保存退出。再执行make和make install。

如果在执行make install安装的过程中，出现如下提示

install -m 755 -s mplayer /home/hxy/MPlayer/
MPlayer-1.0rc2/../output/arm_linux/bin
strip: Unable to recognise the format of the input file 
`/home/hxy/MPlayer/MPlayer-1.0rc2/../output/arm_linux/bin/mplayer'

这个时候修改Makefile文件，将第24行INSTALLSTRIP = -s 中的-s注释掉，如下

vim Makefile

# Do not strip the binaries at installation
ifeq ($(STRIPBINARIES),yes)
INSTALLSTRIP = #-s
endif

再make install ，得到mplayer可执行文件，结束。
