Android中的ffmpeg + libfaac编译错误

Question

我已成功集成并编译了libfaac中的ffmpeg。当我试图编译libfaac功能我得到这个错误：

/home/admin1/Desktop/android/workspace/.../obj/local/armeabi/libavcodec.a(libfaac.o): In function `Faac_encode_close': 
/home/admin1/Desktop/android/workspace/.../jni/ffmpeg/libavcodec/libfaac.c:145: undefined reference to `faacEncClose'

collect2: ld returned 1 exit status 
make: *** [/home/admin1/Desktop/android/workspace/.../obj/local/armeabi/libxyz.so] Error 1 

我不知道为什么我得到这个错误。

任何帮助，将不胜感激......

我解决了使用Android.mk的LOCAL_LDLIBS ......

我忘了添加引用我libfaac.a文件Android.mk它：

LOCAL_LDLIBS := -ldl -lgcc -llog -lz -lm -lc -lstdc++ -L$(LOCAL_PATH) -lfaac
