1. 准备两份mplayer，一份为$MPLAYER-WORK，一份为$MPLAYER- BAK;
2. 执行$MPLAYER-BAK/configure;
3. vim $MPLAYER-WORK/configure，去掉里面所有的优化选项，-O2 -O3 -O4;
4. $MPLAYER-WORK/configure --enable-debug;
5. cp -f $MPLAYER-BAK/config.mak $MPLAYER-WORK/ffmpeg/;
6. $MPLAYER-WORK/make;
7. 在编译的过程中如果出现错误，则需要单独编译该xxxx.o文件，将出错地方的编译的指令中的-Wall后加上-O2单独编译，然后继续make
