ExifInterface constructor throws an IOExxception

I am having trouble throwing an exception that is thrown by the ExifInterface constructor when trying to initialize an exif interface instance using the file path.

UPDATED Please see the detailed code below as requested.

File upload function

public void downloadAndSaveFile(String url, String directoryId, String fileName) {
    HttpURLConnection conn = null;

        conn.connect();

OrientBitmap and rotateBitmap Functions

public static Bitmap orientBitmap(String filePath, Bitmap bitmap) throws IOException {
    Log.d(TAG, "orientBitmap FilePath : " + filePath);
    File file = new File(filePath);
    Log.d(TAG, "orientBitmap File exists : " + file.exists());

    ExifInterface exifInterface = new ExifInterface(filePath);
    Log.d(TAG, "After exception");
    int orientation = exifInterface.getAttributeInt(ExifInterface.TAG_ORIENTATION, ExifInterface.ORIENTATION_NORMAL);

    Log.d(TAG, "Thumb orientation : " + orientation);

    switch (orientation) {
        case ExifInterface.ORIENTATION_ROTATE_90:
            bitmap = rotateBitmap(bitmap, 90);
            break;
        case ExifInterface.ORIENTATION_ROTATE_180:
            bitmap = rotateBitmap(bitmap, 180);
            break;
        case ExifInterface.ORIENTATION_ROTATE_270:
            bitmap = rotateBitmap(bitmap, 270);
            break;
    }
    return bitmap;
}

public static Bitmap rotateBitmap(Bitmap source, float angle) {
    Matrix matrix = new Matrix();
    matrix.postRotate(angle);
    return Bitmap.createBitmap(source, 0, 0, source.getWidth(), source.getHeight(), matrix, true);
}

I update the stack trace by tracing the stack when trying to generate a thumbnail of the mp4 file and png file.

Stack trace for mp4 file.
