• Exoplayer FFmpeg support

  12 octobre 2016, par srujith poondla

  I am using Android-FFmpeg .aar file fromAndroid-FFmpeg for loading FFmpeg binaries. Is there any way to link the ffmpeg command line output from that module to exoplayer so that it streams the video with out saving the video. Otherwise should i have to develop some FFmpeg decoder to decode video as an extension to exoplayer using Media Codec Renderer ?

• Android NDK Linking shared library unsatisfied Linker Error

  6 janvier 2014, par nmxprime

  i have a problem,

  Below is the Android.mk

  LOCAL_PATH := $(call my-dir)
  
  INITIAL_PATH := $(LOCAL_PATH)
  
  
  
  include $(CLEAR_VARS)
  
  LOCAL_MODULE := ffmpegbuilt
  
  LOCAL_SRC_FILES := libffmpeg.so
  
  LOCAL_EXPORT_C_INCLUDES := $(LOCAL_PATH)/
  
  include $(PREBUILT_SHARED_LIBRARY)
  
  
  
  
  
  LOCAL_PATH := $(INITIAL_PATH)
  
  LOCAL_MODULE    := main_module
  
  LOCAL_ARM_MODE := arm  # remove this if you want thumb mode
  
  LOCAL_SRC_FILES := main.c
  
  LOCAL_LDLIBS := -llog
  
  LOCAL_SHARED_LIBRARIES := ffmpegbuilt
  
  include $(BUILD_SHARED_LIBRARY)

  It creates the two shared_libraries as expected. i see those two libraries inside libs/armeabi folder
  When i run the application, Unsatisfied Linker error occurs as

  01-06 20:21:38.281: E/AndroidRuntime(435): FATAL EXCEPTION: main
  
  01-06 20:21:38.281: E/AndroidRuntime(435): java.lang.UnsatisfiedLinkError: Cannot load library: link_image[1962]:    32 could not load needed library 'libffmpeg.so' for 'libmain_module.so' (load_library[1104]: Library 'libffmpeg.so' not found)

  01-06 20:21:38.281: E/AndroidRuntime(435):  at java.lang.System.loadLibrary(System.java:554)

  What could be the problem, also though i defined LOCAL_MODULE := ffmpegbuilt, why the prebuilt library's module name is not changing ?

  i am trying to build some of the files from libavcodec and libavutil

  The problem addressed here is not relavant to what i am facing, though the error is similar.

  The error i got is :

  Android NDK: jni/inner/Android.mk:mylib: LOCAL_MODULE_FILENAME should not include file extensions
  
  Android NDK: jni/inner/Android.mk:mylib: LOCAL_MODULE_FILENAME must not contain a file extension

  Please help !!
