imx6ul上mplayer的移植

安装libmad，这里使用版本libmad-0.15.1b.tar.gz
下载链接：ftp://ftp.mars.org/pub/mpeg/
安装Mplayer，这里使用版本MPlayer-1.0rc2.tar.bz2
下载链接：http://www.mplayerhq.hu/MPlayer/releases/

环境：Ubuntu16.04 64位
工具链版本：4.9.4
目标平台：TQ.IMX6UL

1.安装libmad

#tar xvf libmad-0.15.1b.tar.gz
#cd libmad-0.15.1b/
#vi mplayer.sh

#!/bin/sh
CC=arm-linux-gnueabihf-gcc ./configure --host=arm-linux  --prefix=/home/mm/work/project/yichuan/embesky/mplayer/mplayer-arm --disable-shared --disable-debugging --enable-speed
#make -j4

#make

编译时会出现以下错误：

arm-linux-gnueabihf-gcc: error: unrecognized command line option '-fforce-mem'

这个要在Makefile中去了-fforce-mem
#vi Makefile
将：

  CFLAGS = -Wall -g -O -fforce-mem -fforce-addr -fthread-jumps -fcse-follow-jumps -fcse-skip-blocks -fexpensive-optimizations -fregmove -fschedule-insns2 -fstrength-reduce

改为：

  CFLAGS = -Wall -g -O  -fforce-addr -fthread-jumps -fcse-follow-jumps -fcse-skip-blocks -fexpensive-optimizations -fregmove -fschedule-insns2 -fstrength-reduce      

保存继续编译
#make
又出现以下问题：

/tmp/ccFLzPIj.s: Assembler messages:
/tmp/ccFLzPIj.s:1308: Error: selected processor does not support Thumb mode `rsc r7,r7,#0'
/tmp/ccFLzPIj.s:1455: Error: selected processor does not support Thumb mode `rsc r9,r9,#0'
/tmp/ccFLzPIj.s:1881: Error: selected processor does not support Thumb mode `rsc r7,r7,#0'
/tmp/ccFLzPIj.s:2023: Error: selected processor does not support Thumb mode `rsc r8,r8,#0'

make[2]: *** [synth.lo] Error 1
make[2]: Leaving directory '/home/mm/work/project/yichuan/embesky/mplayer/libmad-0.15.1b'
Makefile:424: recipe for target 'all-recursive' failed
make[1]: *** [all-recursive] Error 1
make[1]: Leaving directory '/home/mm/work/project/yichuan/embesky/mplayer/libmad-0.15.1b'
Makefile:249: recipe for target 'all' failed
make: *** [all] Error 2

在配置时加上–enable-speed参数即可
#make
#make install
最终的编译脚本为mplayer.sh

#!/bin/sh
CC=arm-linux-gnueabihf-gcc 
./configure \
--host=arm-linux \  
--prefix=/home/mm/work/project/yichuan/embesky/mplayer/mplayer-arm  \
--disable-shared  \
--disable-debugging  \
--enable-speed \
make -j4 
make install

最终在–prefix指定的路径生成头文件和库文件

2.编译安装Mplayer
#tar xvf MPlayer-1.0rc2.tar.bz2
#cd MPlayer-1.0rc2/
#vi mplayer.sh

#!/bin/sh
./configure --prefix=/home/mm/work/project/yichuan/embesky/mplayer/mplayer-arm  --cc=arm-linux-gnueabihf-gcc --disable-gui  --target=arm-linux  --host-cc=gcc  --disable-freetype  --enable-fbdev  --disable-mencoder   --disable-sdl --disable-live  --disable-dvdread  --disable-libdvdcss-internal --disable-x11 --enable-cross-compile  --disable-dvdnav --disable-dvdread-internal --disable-jpeg --disable-tga --disable-pnm --disable-tv --disable-ivtv --disable-fontconfig --disable-xanim --disable-win32dll --disable-armv5te --disable-armv6 --enable-static

make

执行脚本编译
#./mplayer.sh
生成可执行文件mplayer

将执行文件mplayer拷贝至arm板/bin目录，另外再拷贝一个mp4文件
mplayer -fs -zoom -x 800 -y 480 /test_file/movie.mp4
-fs 视频图像居中
-zoom -x 800 -y 480 设置大小（具体按自己的开发板LCD分辨率设置）
