2.解压 文件
3.进入 root@yuweixian:/home/ywx/yu/src# cd cd MPlayer-1.0rc4/ 编译配置
- root@yuweixian:/home/ywx/yu/src/MPlayer-1.0rc4# ./configure --host-cc=gcc --cc=arm-linux-gcc --target=arm-armv4l-linux --enable-static --prefix=/home/ywx/yu/src/mplayer --disable-win32dll --disable-dvdread --enable-fbdev --disable-mencoder --disable-live 2>&1 | tee logfile
4. make 编译
注：这里会出错，在libmpeg2/motion_comp_arm_s.S文件的最前面加上如下的内容：
- #ifndef HAVE_PLD
-
.macro pld reg
-
.endm
-
#endif
5.再次 make
然后再次 make 编译，这次编译没有了错误，
最后在 /home/ywx/yu/src/mplaye/ 生成了 bin etc lib
在 bin/下面 生成了 mplayer 大约 11MB
这里会提示不能更改权限的错误，我们需要手动 改变权限
chmod 777 bin/mplayer
上传 mplayer 附件，一共分成了3个压缩包上传不了
mplayer.part1.rar mplayer.part2.rar mplayer.part3.rar madplay还有一些快捷键，比如：增大/减小音量（+/-），暂停（b），停止
(ESC/s)，回车（从头播放）其他的操作可以查看madplay的源码。6.处理好了。。
7.通过nfs 文件加载到 开发板上
[root@yuweixian /mnt]# mount -t nfs 192.168.1.8:/home/ywx/yu /mnt/nfs -o proto=tcp -o nolock
./mplayer testbeijing.avi 注意这里需要时320*240 的视频
8.查看结果
mplayer直接默认将视频输出到/dev/fb0，事实上是可以通过-vo fb来指定。
[root@yuweixian yu]# cd test-avi/
[root@yuweixian test-avi]# ls
mplayer testbiejing.avi
[root@yuweixian test-avi]# ./mplayer testbiejing.avi
