• W/System.err : java.lang.Exception : FFmpeg not loaded

  1er juillet 2021, par numa

  I ran an android machine learning code that uses AndroidAudioConverter from https://github.com/adrielcafe/AndroidAudioConverter, but I got the different errors as following.
  

  


  When I ran it with AVD emulator, it said (the error is in red font) :

  


  E/FFmpeg: issue in coping binary from assets to data.

  But if I ran it on my android smartphone, I am getting the following error :

  Also, when ran on an android smartphone and emulator simultaneously, I got the following error :

  I used the Android 10 smartphone and Android 9 for AVD. This is a team project, which my friend build. It can run on his smartphone (Android 9). I need to connect the program to the cloud storage but I don't know why it ain't running on my device or emulator.
  
If anyone knows how to resolve this issue please help.
  
Thanks.

  


• How to compile and use FFMPEG library in Android Studio ?

  9 avril 2016, par destroyer25t

  i’m newbie in Android Developing. I need use some video library to decompose my video. I have chose FFMPEG, and faced with a question - how integrate ffmpeg to my application and how to use it ? I have Android Studio on Windows.

• Building with Visual Studio 2010, MFC, and FFmpeg

  11 janvier 2013, par spurgeon

  I'm working on building a Windows MFC application in Visual Studio 2010 using FFmpeg and SDL. However, I can't get the project to build after creating an MFC project from scratch and including the FFmpeg development libraries (avcodec.lib, avdevice.lib, avformat.lib, etc.). I'm using the development build from Zeranoe FFmpeg. I have configured the following in the Project Properties :

  1. Set VC++ Directories -> Include Directories (added the FFmpeg "include" directories)
  2. Set VC++ Directories -> Library Directories (to the FFmpeg "lib" directory)
  3. Set Linker -> Input -> Additional Dependencies (to include avcodec.lib, etc.)

  For what it's worth, the build succeeds when I omit FFmpeg's "include\libavutil" include from the VC++ Directories -> Include Directories.

  Below are some of the first build errors I'm receiving (I won't post all, since it's long). Any help would be appreciated.

  ClCompile:
stdafx.cpp

  Build FAILED.

  I've referenced both of these articles, which were of help :

  • Visual Studio and libavcodec
  • Visual Studio and SDL
