  • Problems with ffmpeg command line on android

    17 mai 2017, par user2193172

    I managed to compile the ffmpeg Static build. But when I am trying to call the ffmpeg command line I get a Java IOException : No such file or Directory.

    My code is as follows :

    public void merge_video(View view){
    

    
    if(ffmpeg_file.exists()){
    
          Log.d(null, "ffmpeg exists");
    
      }else{
    
          Log.d(null, "Could not locate ffmpeg in the folder");
    
      }
    

    
      File file1 = new File("/mnt/sdcard/com.ffmpeg_test/VID_3_25_2013_12_22.mp4");
    
      if(file1.exists()){
    
          Log.d(null,"File 1 exists");
    
      }
    
      File file2 = new File("/mnt/sdcard/com.ffmpeg_test/VID_3_25_2013_12_28.mp4");
    
      if(file2.exists()){
    
          Log.d(null,"File 2 exists");
    
      }
    

    
      String[] ffmpegCommand = new String[5];
    
      ffmpegCommand[0] = "/mnt/sdcard/com.ffmpeg_test/ffmpeg";
    
      ffmpegCommand[1] = "-i";
    
      ffmpegCommand[2] = "concat:/mnt/sdcard/com.ffmpeg_test/VID_3_25_2013_12_22.mp4|/mnt/sdcard/com.ffmpeg_test/VID_3_25_2013_12_28.mp4";
    
      ffmpegCommand[3] = "copy";
    
      ffmpegCommand[4] = "/mnt/sdcard/com.ffmpeg_test/output.mp4";  
    

    
      try {
    
          Process ffmpegProcess = new ProcessBuilder(ffmpegCommand).redirectErrorStream(true).start();
    

    
          String line;
    
          BufferedReader reader = new BufferedReader(new InputStreamReader(ffmpegProcess.getInputStream()));
    
          Log.d(null, "*******Starting FFMPEG");
    

    
          while((line = reader.readLine())!=null){
    

    
              Log.d(null, "***"+line+"***"); 
    
          }
    
          Log.d(null,"****ending FFMPEG****");
    

    
    } catch (IOException e) {
    
        e.printStackTrace();
    
    }
    
  }

  • Working Directory : null Environment : null when trying to call compiled FFMPEG in android

    10 janvier 2013, par TharakaNirmana

    I have the compiled FFMPEG file. I try to combine an image and an audio clip to form a video clip. Function to combine those two are : ffmpeg -i /mnt/sdcard/KaraokeVideos/allmapeople.mp3 -i /mnt/sdcard/KaraokeVideos/Penguins.jpg /mnt/sdcard/KaraokeVideos/video_finale.mpg.

    I have used that in the code :

    public class MainActivity extends Activity {
    

    
    private Process process;
    
    String command, text;
    

    
    // load the library - name matches jni/Android.mk-jj
    
    //static {
    

    
        //System.loadLibrary("ffmpeg");
    
    //}
    

    

    

    
    @Override
    
    public void onCreate(Bundle savedInstanceState) {
    
        super.onCreate(savedInstanceState);
    
        setContentView(R.layout.activity_main);
    
        try {
    
            Execute();
    
        } catch (IOException e) {
    
            // TODO Auto-generated catch block
    
            e.printStackTrace();
    
        }
    

    

    
    } 
    

    
    private void Execute() throws IOException {
    
        // TODO Auto-generated method stub
    

    
        Process p = Runtime.getRuntime().exec("ffmpeg -i /mnt/sdcard/KaraokeVideos/allmapeople.mp3 -i /mnt/sdcard/KaraokeVideos/Penguins.jpg /mnt/sdcard/KaraokeVideos/video_finale.mpg");
    
        p.getInputStream();
    
    }

    But I get this exception in logcat :
