UnsatisfiedLInkError Verknüpfung mit FFMPEG mit NDK

Question

Ich habe FFMPEG für Android unter Verwendung der Dateien von bambuser kompiliert. Die Kompilierung läuft gut. Keine Fehler. Ich habe auch dafür gesorgt, dass der Paketname in build.sh geändert wird. Sobald ich jedoch versuche, die Dateien zu verlinken, gibt das Telefon einen UnsatisfiedLinkError aus. Dies ist die Datei Androkd.mk:

LOCAL_PATH := $(call my-dir)

include $(CLEAR_VARS)
MY_LIB_PATH := ffmpeg-android/build/ffmpeg/armeabi/lib
LOCAL_MODULE := bambuser-libavcore
LOCAL_SRC_FILES := $(MY_LIB_PATH)/libavcore.so
include $(PREBUILT_SHARED_LIBRARY)

include $(CLEAR_VARS)
LOCAL_MODULE := bambuser-libavformat
LOCAL_SRC_FILES := $(MY_LIB_PATH)/libavformat.so
include $(PREBUILT_SHARED_LIBRARY)

include $(CLEAR_VARS)
LOCAL_MODULE := bambuser-libavcodec
LOCAL_SRC_FILES := $(MY_LIB_PATH)/libavcodec.so
include $(PREBUILT_SHARED_LIBRARY)

include $(CLEAR_VARS)
LOCAL_MODULE := bambuser-libavdevice
LOCAL_SRC_FILES := $(MY_LIB_PATH)/libavdevice.so
include $(PREBUILT_SHARED_LIBRARY)

include $(CLEAR_VARS)
LOCAL_MODULE := bambuser-libavfilter
LOCAL_SRC_FILES := $(MY_LIB_PATH)/libavfilter.so
include $(PREBUILT_SHARED_LIBRARY)

include $(CLEAR_VARS)
LOCAL_MODULE := bambuser-libavutil
LOCAL_SRC_FILES := $(MY_LIB_PATH)/libavutil.so
include $(PREBUILT_SHARED_LIBRARY)

include $(CLEAR_VARS)
LOCAL_MODULE := bambuser-libswscale
LOCAL_SRC_FILES := $(MY_LIB_PATH)/libswscale.so
include $(PREBUILT_SHARED_LIBRARY)

#local_PATH := $(call my-dir)

include $(CLEAR_VARS)

LOCAL_MODULE    := libtest_jni
LOCAL_SRC_FILES := libtest/video.c

LOCAL_C_INCLUDES := \
    $(LOCAL_PATH)/include \
        $(LOCAL_PATH)/ffmpeg-android/ffmpeg 
        LOCAL_LDLIBS := -L$(NDK_PLATFORMS_ROOT)/$(TARGET_PLATFORM)/arch-arm/usr/lib -L$(LOCAL_PATH) -L$(LOCAL_PATH)/ffmpeg-android/build/ffmpeg/armeabi/lib/ -lavformat -lavcodec -lavdevice -lavfilter -lavutil -lswscale -llog -lz -lm
        #dl -lgcc

        include $(BUILD_SHARED_LIBRARY)

Video.c ist ganz einfach:

#include <libavcodec/avcodec.h>
#include <libavformat/avformat.h>
#include <libswscale/swscale.h>

#include <jni.h>  
#include <string.h>  
#include <stdio.h>
#include <android/log.h>  

void Java_com_bukabros_videolivewallpaper_Opengl2Renderer_loadNthFrame3
       (JNIEnv * env, jobject this, jstring fileName)  {

       jboolean isCopy;  
         const char * szLogThis = (*env)->GetStringUTFChars(env, fileName, &isCopy);  

          __android_log_print(ANDROID_LOG_DEBUG, "NDK: ", "NDK:LC: [%s]", szLogThis); 
          }   

Der entsprechende Java-Code ist ebenfalls einfach:

 private native void loadNthFrame3(String fileName);

 static {  
System.loadLibrary("libtest_jni");  
 }  

Aber ich bekomme diesen Fehler:

Ich habe versucht, die vorgefertigten gemeinsamen Bibliotheken (die bambuser-Dateien) manuell in Java zu laden (mit System.loadLibrary), aber dann wird mir mitgeteilt, dass die Dateien nicht gefunden werden.

Falls es hilft, hier ist die Ausgabe von readelf:

Ach ja. Ich benutze ndk r5.
