Running ffmpeg command on Android results in "Unable to find a suitable output format for ' -map 0:v:0 -map 1:a:0'"

Question

I am using this command for replacing audio of video and genrate new video having new audio. Here file1 is my video.mp4, file2 is my audio.mp3 and output would be the output.mp4:

complexCommand = new String[]{"-y", "-i", file1.toString(), "-i", file2.toString(), "-c", "copy", " -map 0:v:0 -map 1:a:0", rootPath + "/output.mp4"};

Below is My code:

    private void changeAudioofVideo(String selectedUri, String videoPath) {

    String[] complexCommand;


    File f = new File("/storage/emulated/0");
    if (!f.getParentFile().exists())
        f.getParentFile().mkdirs();
    if (!f.exists())
        try {
            f.createNewFile();
        } catch (IOException e) {
            e.printStackTrace();
        }

    file1 = new File(videoPath);
    if (file1.exists()) {
        Log.d("yes", "File 1 exists");
    } else {
        Log.d("no", "File 1 not exists");
    }

    file2 = new File(selectedUri);
    if (file2.exists()) {
        Log.d("yes", "File 1 exists");
    } else {
        Log.d("no", "File 1 not exists");
    }

    String rootPath = f.getPath();

    complexCommand = new String[]{"-y", "-i", file1.toString(), "-i", file2.toString(), "-c", "copy", " -map 0:v:0 -map 1:a:0", rootPath + "/output.mp4"};

    FFmpeg ffmpeg = FFmpeg.getInstance(this);

    try {
        //Load the binary
        ffmpeg.loadBinary(new LoadBinaryResponseHandler() {

            @Override
            public void onStart() {
            }

            @Override
            public void onFailure() {
            }

            @Override
            public void onSuccess() {
            }

            @Override
            public void onFinish() {
            }
        });
    } catch (FFmpegNotSupportedException e) {
        // Handle if FFmpeg is not supported by device
        Toast.makeText(getApplicationContext(), "Not Supported by Device", Toast.LENGTH_LONG).show();
    }

    try {

        final String finalRootPath = rootPath;
        ffmpeg.execute(complexCommand, new FFmpegExecuteResponseHandler() {
            @Override
            public void onSuccess(String message) {
                Log.d("Success", message);

                Toast.makeText(getApplicationContext(), "Successful" + finalRootPath.toString(), Toast.LENGTH_LONG).show();
                Uri path = Uri.parse(finalRootPath + "/output.mp4");
                playVideo(path.toString());

            }

            @Override
            public void onProgress(String message) {
                Log.d("progress", message);
                pd.show();
            }

            @Override
            public void onFailure(String message) {
                Log.d("failure", message);
                pd.dismiss();

            }

            @Override
            public void onStart() {
                Log.d("Start", "merge started");
            }

            @Override
            public void onFinish() {
                Log.d("finish", "merge finish");
                pd.dismiss();
            }
        });
    } catch (FFmpegCommandAlreadyRunningException e) {
        e.printStackTrace();
    }


   }

Answer 1

You are not consistent in the way you construct your command.

You should split it into individual arguments:

complexCommand = new String[]{"-y", "-i", file1.toString(), "-i", file2.toString(), "-c", "copy", "-map", "0:v:0", "-map", "1:a:0", rootPath + "/output.mp4"};
