    import com.github.hiteshsondhi88.libffmpeg.exceptions.FFmpegCommandAlreadyRunningException;
    
    public class MergeAudioVideoTask extends AsyncTask {
        private static final String TAG = MergeAudioVideoTask.class.getSimpleName();
    
        private Context context;
        private String videoFilePath;
        private final String audioFilePath;
        private final String outputFilePath;
    
        public MergeAudioVideoTask(String videoFilePath, String audioFilePath, String outputFilePath) {
            this.videoFilePath = videoFilePath;
            this.audioFilePath = audioFilePath;
            this.outputFilePath = outputFilePath;
        }
    
    //    String inputAudioPath = "https://www.soundhelix.com/examples/mp3/SoundHelix-Song-1.mp3";
        String outputVideoPath = Environment.getExternalStorageDirectory() + "/trimVideos" + "sangtest.mp4";
    
    //    String[] command = {"-i", vpath, "-i", inputAudioPath, "-c:v", "copy", "-c:a", "aac", "-map", "0:v:0", "-map", "1:a:0", "-shortest", outputVideoPath};
    
    
        @Override
        protected Boolean doInBackground(Void... params) {
            String[] cmd = {"-i", videoFilePath, "-i", audioFilePath, "-shortest", outputVideoPath};
            try {
                FFmpeg.getInstance(context).execute(cmd, new ExecuteBinaryResponseHandler() {
                    @Override
                    public void onStart() {
                        Log.e("Started", "yes");
                    }
    
                    @Override

• Pydub unable to locte ffprobe

  22 décembre 2020, par Recessive

  First of all, here is the link to a similar question to this : Pydub (WindowsError : [Error 2] The system can not find the file specified)
Although in this one the problem is with ffmpeg, which I solved by setting the absolute path.

  



  After setting the absolute path for converter and/or ffmpeg with either :

  



  AudioSegment.converter = r'C:\ffmpeg\bin'

  



  or

  



  AudioSegment.ffmpeg = r'C:\ffmpeg\bin'

  



  I still get this error :

  



  


  C :\Program Files\Python36\lib\site-packages\pydub\utils.py:193 : RuntimeWarning : Couldn't find ffprobe or avprobe - defaulting to ffprobe, but may not work
 warn("Couldn't find ffprobe or avprobe - defaulting to ffprobe, but may not work", RuntimeWarning)

 File "C :\Program Files\Python36\lib\subprocess.py", line 990, in _execute_child
 startupinfo)
 FileNotFoundError : [WinError 2] The system cannot find the file specified`

  


  



  I have ffmpeg in my path envvar. I also have libav in my path envvar, and installed libav and then pydub in the order specified at https://github.com/jiaaro/pydub#dependencies.

  



  Nothing I'm doing appears to be working, so any ideas or solutions would be greatly appreciated !
