• Error FFmpeg in Android

  19 novembre 2013, par Mark

  I'm using FrameGrabber to load a video from sdcard and perform some image processing operation. I followed the tutorial at JavaCV site to load javacc and ffmpeg.
  Currently, to run the application, I'm using my tablet (Asus TF 101G with Android version 4.0.3) connected to my pc and it works fine. But if I try to run the same application in another device (e.g. Nexus with Android 4.1.2) I get these errors :

  Any suggestion please ?

  I want to attach also my Android.mk file

  LOCAL_PATH := $(call my-dir)
  
  include $(CLEAR_VARS)
  
  OPENCV_LIB_TYPE:=STATIC
  
  include C:/Users/Marco/Desktop/new_ADT/adt-bundle-windows-x86_64/OpenCV-2.4.3.2-android-sdk/sdk/native/jni/OpenCV.mk
  
  OPENCV_INSTALL_MODULES:=on
  
  #OPENCV_CAMERA_MODULES:=on
  
  LOCAL_MODULE    := udmodule
  
  LOCAL_SRC_FILES := udjni.cpp
  
  LOCAL_LDLIBS +=  -llog -ldl
  
  include $(BUILD_SHARED_LIBRARY)

  and my Apllication.mk file

  APP_STL := gnustl_static
  
  APP_CPPFLAGS := -frtti -fexceptions
  
  APP_ABI := armeabi armeabi-v7a 
  
  #APP_ABI := all
  
  APP_PLATFORM := android-8

  Any suggestion ?
  Thanks

  Also I tried to change the application.mk file in this way but with no results :

  APP_STL := gnustl_static
  
  APP_CPPFLAGS := -frtti -fexceptions
  
  APP_ABI := armeabi
  
  LOCAL_CFLAGS += -march=armv7-a -mfloat-abi=softfp -mfpu=vfp -mfpu=neon
  
  LOCAL_LDLIBS += -Wl,--fix-cortex-a8
  
  APP_PLATFORM := android-8
