【目的】
把我的mplayer的vbr的patch加到buildroot的mplayer中
【方法】
1.确定buildroot中的mplayer的patch的命名规则，这个可以在
先去删除buildroot中的mplayer：
rm build_arm/MPlayer-1.0rc1/ -r
然后直接make，编译输出过程中就有对应信息：
[root@linux-41lh buildroot]$>make
Checking build system dependencies:
BUILDROOT_DL_DIR clean: Ok
CC clean: Ok
。。。。。。。。
rm -rf /root/buildroot/buildroot/project_build_arm/uclibc/buildroot-config
mkdir -p /root/buildroot/buildroot/project_build_arm/uclibc
cp -dpRf package/config/buildroot-config /root/buildroot/buildroot/project_build_arm/uclibc/buildroot-config
bzcat /root/buildroot/buildroot/dl/MPlayer-1.0rc1.tar.bz2 | tar -C /root/buildroot/buildroot/build_arm -xf –
toolchain/patch-kernel.sh /root/buildroot/buildroot/build_arm/MPlayer-1.0rc1 package/mplayer/ mplayer-1.0rc1*.patch*
Applying mplayer-1.0rc1-atmel.3.patch using plaintext:

touch /root/buildroot/buildroot/build_arm/MPlayer-1.0rc1/.unpacked
(cd /root/buildroot/buildroot/build_arm/MPlayer-1.0rc1; rm -rf config.cache;
说明patch名字符合 mplayer-1.0rc1*.patch* 即可。
所以，把自己patch改名符合条件的：mplayer-1.0rc1_vbr_fixedMad.patch
2.把patch拷贝到对应文件夹下：
拷贝mplayer-1.0rc1_vbr_fixedMad.patch到 package/mplayer/ 下面。
这样，make的时候，就会自动找到该patch，并执行它：
。。。。。。。。
rm -rf /root/buildroot/buildroot/project_build_arm/uclibc/buildroot-config
mkdir -p /root/buildroot/buildroot/project_build_arm/uclibc
cp -dpRf package/config/buildroot-config /root/buildroot/buildroot/project_build_arm/uclibc/buildroot-config
bzcat /root/buildroot/buildroot/dl/MPlayer-1.0rc1.tar.bz2 | tar -C /root/buildroot/buildroot/build_arm -xf –

另外要说明一点是，为了确保你的patch正常工作了，你要保证出来的patch，是用-p1去使用的。
因为，buildroot中就是去根据
package/mplayer/mplayer.mk
中的要求，调用toolchain/patch-kernel.sh去应用patch的，而toolchain/patch-kernel.sh里面，是用-p1的：
echo "Applying ${i} using ${type}: "
${uncomp} ${patchdir}/${i} | patch -p1 -E -d ${targetdir}
