UnsatisfiedLInkError NDK ile FFMPEG'ye bağlanma

Question

Ben bambuser dosyalarını kullanarak android için FFMPEG derledim. Derleme iyi çalışıyor. Hata yok. Ayrıca paket adını build.sh olarak değiştirmeyi de ihmal etmekteyim. Ancak, dosyalara bağlanmayı denediğimde, telefon bir UnsatisfiedLinkError atar.

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 ölü basittir: Bu Androkd.mk dosyasıdır

#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); 
      } 

Tne gelen Java kodu da basittir:

private native void loadNthFrame3(String fileName); 

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

Ama bu hatayı alıyorum:

El ile yüklemeyi denedim g Java'da önceden oluşturulmuş paylaşılan kütüphaneler (bambuser dosyaları) (System.loadLibrary kullanarak) ancak daha sonra dosyaların bulunmadığını söyler. Eğer yardımcı olur

Yanıtı bulmuş gibi görünüyor. Sorun, kütüphaneyi Java'ya yüklediğinizde (System.loadLibrary) "lib" önekini kullanamazsınız. Java'da ffmpeg kitaplıklarını elle yüklemem gerekiyordu. çok faydalı oldu, Androkd.mk yazabilmek için

static { 
System.loadLibrary("avcore"); 
System.loadLibrary("avformat"); 
System.loadLibrary("avcodec"); 
System.loadLibrary("avdevice"); 
System.loadLibrary("avfilter"); 
System.loadLibrary("avutil"); 
System.loadLibrary("swscale"); 
System.loadLibrary("test_jni"); 
}
