  java.io.IOException : Error running exec() Working Directory : null Environment : null FFmpeg Android merging mp3 and mp4

  



  I am trying following code

  



  public class Minact1 extends Activity{
    String  videoFilePath,audioFilePath,outputFilePath;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.mainact);
        videoFilePath = Environment.getExternalStorageDirectory()
                .getAbsolutePath() + "/sample2.mp4";
        audioFilePath = Environment.getExternalStorageDirectory()
                .getAbsolutePath() + "/abc.mp3";
        outputFilePath = Environment.getExternalStorageDirectory()
                .getAbsolutePath() + "/output.mp4";

        try {


            FFmpeg ffmpeg = FFmpeg.getInstance(this);
            String[] cmd =
                    {"-i " + videoFilePath + " -i " + audioFilePath +
                            " -shortest -threads 0 -preset ultrafast -strict -2 " + outputFilePath};

            ffmpeg.execute(cmd, mergeListener);
        } catch (FFmpegCommandAlreadyRunningException e) {
            e.printStackTrace();

            Toast.makeText(Minact1.this, "" +  e, Toast.LENGTH_SHORT).show();
        }
    }

    ExecuteBinaryResponseHandler mergeListener = new ExecuteBinaryResponseHandler() {
        @Override
        public void onStart() {
            //started
            Toast.makeText(Minact1.this, "started", Toast.LENGTH_SHORT).show();
        }

        @Override
        public void onFailure(String message) {
            //failed
            Toast.makeText(Minact1.this, "failed", Toast.LENGTH_SHORT).show();
        }

        @Override
        public void onFinish() {
            File output = new File(outputFilePath);
            //Do whatever with your muxed file

            Toast.makeText(Minact1.this, "onFinish", Toast.LENGTH_SHORT).show();
        }
    };
}


  



  I have used following library for FFmpeg

  



  dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    testCompile 'junit:junit:4.12'
    compile 'com.android.support:appcompat-v7:23.1.1'

    androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
        exclude group: 'com.android.support', module: 'support-annotations'
    })

    compile 'com.android.support:design:23.1.1'
    compile 'com.writingminds:FFmpegAndroid:0.3.2'

    compile 'com.android.support:cardview-v7:23.1.1'
    compile 'commons-io:commons-io:2.5'
}


  



  and added following permission in manifest

  



  
    


  



  the files are present at the path used , but output.mp4 is not created

  



  the log says

  I get the following error while I'm playing YouTube audio with my bot

  It seems like YouTube links expire ? I don't really know but I need to fix this issue. This is my code :

  I'm using the rewrite branch of discord.py for the bot.
I'm not sure if I need to provide more details ? Please let me know, I really need to get this fixed...

  


• FFmpeg record and stream

  16 janvier 2019, par Robert

  I’m getting the following error.

     E/FFmpeg: Exception while trying to run: 
  
     [/data/user/0/com.example.pathways.testipcam/files/ffmpeg, -y, -i, 
  
    rtsp://log:pass@IP:port/video.h264, -acodec, copy, -vcodec, copy, -t, 
  
  00:03:00, 
  
   content://com.example.android.fileprovider/external_files/Android/data/com.example.pathways.testipcam/files/Movies/IPcam_20190116_150628_6019720208966811003.m>kv]
  
  java.io.IOException: Cannot run program "/data/user/0/com.example.pathways.testipcam/files/ffmpeg": error=2, No such >file or directory

  OK I’m trying to learn how to record and stream my IP cam on android. I can stream the video in a surface view media player no problem so I then went to the record task. Now I’m a bit lost. I know this is possible as I have read people say they used this to do it.

  I started with implamenting

   implementation 'nl.bravobit:android-ffmpeg:1.1.5'

  But I can’t figure out what I am missing or doing wrong as there aren’t really any tutorials explaining this completely. So hopefully this can be the thread everyone else finds for a solution. I have listed my code below. Exactly what have I got wrong here. It runs and goes to onStart...then right on onFailure.
  DO I need to have 2 streams in order to view and watch ? or what the deal.
  I know FFmpeg can do that.
  "ffmpeg supports multiple outputs created out of the same input(s) in the same process. The usual way to accomplish this is :

  ffmpeg -i input1 -i input2 \
  -acodec … -vcodec … output1 \
  -acodec … -vcodec … output2 \"

  but I have no idea how to sue that.
  Anyway, I know I’m kind of close, at least I hope I need a little help on getting over the finish line on this. What have I done wrong, how does this work.

  Here is what I did, I streamed the video as the app does. no problem

      surfaceView = (SurfaceView) findViewById(R.id.videoView);
  
      _surfaceHolder = surfaceView.getHolder();
  
      _surfaceHolder.addCallback(this);
  
      _surfaceHolder.setFixedSize(320, 240);
  
  
  
   ....
  
  
  
   @Override
  
  public void surfaceCreated(SurfaceHolder holder) {
  
      mpPlayerRun();
  
  
  
  }
  
  
  
  public void mpPlayerRun(){
  
      _mediaPlayer = new MediaPlayer();
  
      _mediaPlayer.setDisplay(_surfaceHolder);
  
  
  
      try {
  
          // Specify the IP camera's URL and auth headers.
  
          _mediaPlayer.setDataSource(RTSP_URL);
  
  
  
          // Begin the process of setting up a video stream.
  
          _mediaPlayer.setOnPreparedListener(this);
  
          _mediaPlayer.prepareAsync();
  
      }
  
      catch (Exception e) {}
  
  }
  
  ...
  
   @Override
  
  public void onPrepared(MediaPlayer mp) {
  
      _mediaPlayer.start();
  
  }

  OK, so then I created a button to record.

  @Override
  
  public void onClick(View view) {
  
      switch (view.getId()) {
  
          case R.id.IPcamback:
  
              break;
  
  
  
          case R.id.IPcamrecord:
  
              if (ContextCompat.checkSelfPermission(this,
  
                      Manifest.permission.WRITE_EXTERNAL_STORAGE) == PackageManager.PERMISSION_GRANTED) {
  
                  takeIPvid();
  
              } else {
  
                  requestIPCamPermission();
  
              }

  .....

  requested permission then results.

      private void requestIPCamPermission() {
  
      if (ActivityCompat.shouldShowRequestPermissionRationale(this,
  
              Manifest.permission.WRITE_EXTERNAL_STORAGE)) {
  
  
  
          new AlertDialog.Builder(this)
  
                  .setTitle("Permission needed")
  
                  .setMessage("This permission is needed do to android safety protocol")
  
                  .setPositiveButton("ok", new DialogInterface.OnClickListener() {
  
                      @Override
  
                      public void onClick(DialogInterface dialog, int which) {
  
                          ActivityCompat.requestPermissions(MainActivity.this,
  
                                  new String[] {Manifest.permission.WRITE_EXTERNAL_STORAGE}, 420);
  
                      }
  
                  })
  
                  .setNegativeButton("cancel", new DialogInterface.OnClickListener() {
  
                      @Override
  
                      public void onClick(DialogInterface dialog, int which) {
  
                          dialog.dismiss();
  
                      }
  
                  })
  
                  .create().show();
  
  
  
      } else {
  
          ActivityCompat.requestPermissions(this,
  
                  new String[] {Manifest.permission.WRITE_EXTERNAL_STORAGE}, 420);
  
      }
  
  }
  
  
  
  @Override
  
  public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
  
  
  
      if (requestCode == 420)  {
  
          if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
  
              takeIPvid();
  
          } else {
  
              Toast.makeText(this, "Permission DENIED", Toast.LENGTH_SHORT).show();
  
          }
  
   .....

  then I made the file provider and createVideoOutputFile() method and the takeIPvid method.

  private File createVideoOutputFile() throws IOException {
  
      String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date());
  
      String imageFileName = "IPcam_" + timeStamp + "_";
  
      IPstorageDir = getExternalFilesDir(Environment.DIRECTORY_MOVIES);
  
      IPvideo_file = File.createTempFile(
  
              imageFileName,  /* prefix */
  
              ".mp4",         /* suffix */
  
              IPstorageDir      /* directory */
  
      );
  
  
  
      // Save a file: path for use with ACTION_VIEW intents
  
      String IPmVideoFilename = IPvideo_file.getAbsolutePath();
  
      return IPvideo_file;
  
  }
  
  
  
     private void takeIPvid() {
  
  
  
          File ipfile = null;
  
          try {
  
              ipfile = createVideoOutputFile();
  
          } catch (IOException e) {
  
              e.printStackTrace();
  
          }
  
      IPvideo_uri = FileProvider.getUriForFile(this,
  
              "com.example.android.fileprovider",
  
              ipfile);
  
  
  
  
  
      String[] cmd = {"-y", "-i", "rtsp://Login:Passord@IP:port/video.h264", "-acodec", "copy", "-vcodec", "copy","-t","00:00:20", IPvideo_uri.toString() };
  
  
  
      FFmpeg.getInstance(this).execute(cmd,new ExecuteBinaryResponseHandler(){
  
  
  
          @Override
  
          public void onStart() {
  
              super.onStart();
  
  
  
  
  
          }
  
  
  
          @Override
  
          public void onFailure(String message) {
  
              super.onFailure(message);
  
  
  
  
  
  
  
          }
  
  
  
          @Override
  
          public void onSuccess(String message) {
  
              super.onSuccess(message);

          @Override
  
          public void onProgress(String message) {
  
              super.onProgress(message);
  
  
  
          }
  
  
  
          @Override
  
          public void onFinish() {
  
              super.onFinish();
  
  
  
          }
  
      });
  
  
  
  }
