    我一直都用0.10.x的版本，2.0版本的我没试过，编译脚本用的同一个，想来问题不大吧，在引用ffmpeg库的时候链接顺序很重要，否则会出现上面的问题，我用的顺序是：LOCAL_LDLIBS := -lz -lswresample -lswscale -lswresample -lavformat -lavcodec -lavutil
      

  4.   

    赐教问题，我编译ffmpeg2.0的时候，我配置ndk正确，测试hello-jni生成了so。
    但是我编译ffmpeg的时候执行，config.sh一直提示没这个命令。找不到目录！

    同求解答，搞了几点都木有在win7+cygwin下编译成功
