      if (inputPath == null || outputPath == null) {
  
          throw new IllegalStateException("Need an input and output filepath!");
  
      }   
  
  
  
      final List<string> cmd = new LinkedList<string>();
  
  
  
  
  
      String baseDir = Environment.getExternalStorageDirectory().getAbsolutePath();
  
      String fileName = "3.mp4";
  
      String fileName1 = "2.mp3";
  
  
  
      String path  = baseDir + "/" + fileName;
  
      String path1  = baseDir + "/" + fileName1;
  
  
  
        File f = new File(path);
  
  
  
        if(f.exists()){
  
            System.out.println("File existed");
  
        }else{
  
            System.out.println("File not found!");
  
        }
  
  
  
        cmd.add(mFfmpegPath);

  10 mai 2014, par Kabir

  I am trying to create online streaming video player in android.
  I am trying to compile the appunite/AndroidFFmpeg library for android application to play HLS videos online. I am using linux-ubuntu OS I also have set the NDK path.
  I have executed all command one by one given on the link :

  https://github.com/appunite/AndroidFFmpeg

  But when I executed the following script :

  ./build_android.sh

  I got the following error :

  abi-gcc —sysroot=/home/singsys-063/android-ndk-r9d/platforms/android-5/arch-arm/
  checking whether the C compiler works... no
  configure : error : in
  /home/singsys-063/AndroidFFmpeg/FFmpegLibrary/jni/vo-amrwbenc :
  configure : error : C compiler cannot create executables
