      '-c:a', 'copy', // Keep original audio
      '-y', // Overwrite existing output file
      outputVideoPath, // Output video path

    await flutterFFmpeg.executeWithArguments(arguments);

    // Save the processed video to the destination directory
    await saveVideoToGallery(outputVideoPath);

Future<void> saveVideoToGallery(String p) async {
    try {

      const absoluteFolderPath = "/storage/emulated/0/desi_charades/";
      await Directory(absoluteFolderPath).create(recursive: true);

      final filename =
          "${deck!.title}_${DateTime.now().millisecondsSinceEpoch}.mp4";
      final destinationPath = "$absoluteFolderPath$filename";

      await originalVideoFile.copy(destinationPath);

      Logger().e(savedPathOfVideo.value);
    } catch (e) {
      print('Error saving enter code here video: $e');
    }
  }

    final arguments = [
    ‘-y’, // Overwrite existing files
    ‘-i’, // Input file
    inputVideoPath,
    ‘drawtext=fontfile=Montserrat-Regular.ttf: text="Pak"’,
    outputVideoPath, // Output file
    ];
    I when i pass the ‘drawtext=fontfile=Montserrat-Regular.ttf: text="Pak"’ then exitcode=1 comes while without using ‘drawtext=fontfile=Montserrat-Regular.ttf: text="Pak"’ result comes exitcode=0 , as I already talked that i want to add text over the video, for this purpose ‘drawtext=fontfile=Montserrat-Regular.ttf: text="Pak"’ is mandatory , can anyone help me
