这几天在做android下的音频播放器，使用ffmpeg做解码器，过程中出现一个问题，执行的时候出现下面这个问题：

都是一些寄存器以及函数地址，真不知道怎么找具体哪个函数出错了，后来网上看到ndk-stack这个工具，很快就定位到错误了

ndk-stack需要log作为输入来分析

adb logcat | $NDK/ndk-stack -sym $PROJECT_PATH/obj/local/armeabi 
也可以把log直接拿出来，再用ndk-stack分析 
adb logcat > /tmp/foo.txt 
$NDK/ndk-stack -sym $PROJECT_PATH/obj/local/armeabi -dump foo.txt
