• Why can’t I run the ffmpeg executable stored in /mnt/sdcard ?

  18 novembre 2024, 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();
    }
  }


  



  The LogCat print is as follows :

• 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 :

  What is wrong here, any help would be great !

• Process not completing ?

  6 mai 2014, par Abe Miessler

  I am using FFMPEG to convert some audio files. To do this I am using the code below :

  using (Process process = new Process())
  
  {
  
      process.StartInfo.RedirectStandardOutput = true;
  
      process.StartInfo.RedirectStandardError = true;
  
      process.StartInfo.FileName = Path.GetDirectoryName(System.Diagnostics.Process.GetCurrentProcess().MainModule.FileName) +
  
                              @"\bin\ffmpeg.exe";
  
  
  
      process.StartInfo.Arguments = String.Format(@"-i {0} -f mp3 {1}", OrigFilePath, OrigFileFolder + "\\" + NewFileName);
  
  
  
  
  
      process.StartInfo.UseShellExecute = false;
  
      process.StartInfo.CreateNoWindow = true;
  
      process.Start();
  
      System.Diagnostics.EventLog.WriteEntry("ASP.NET 2.0.50727.0", "test... ");
  
      string output = process.StandardOutput.ReadToEnd() + System.Environment.NewLine + process.StandardError.ReadToEnd();
  
      System.Diagnostics.EventLog.WriteEntry("ASP.NET 2.0.50727.0", "Output from process: " + output);
  
      process.WaitForExit();
  
      System.Diagnostics.EventLog.WriteEntry("ASP.NET 2.0.50727.0", "After end... ");
  
  
  
      return true;
  
  }

  In my event log I see the test... log, but I never get to the Output from process: in the logs. It appears that the process is not completing. Has anyone else run into this problem ? Any idea of what is going on and how I can fix it ?
