[SOLVED] Video file streaming from java server to iPhone

I have this java servlet which serves video, this works fine in desktop and Android browsers but in iPhone video is not displayed.

here is my servlet code.

    OutputStream output;
    try (InputStream input = new FileInputStream(videoPath)) {
    response.setContentType("video/mp4");
    response.setHeader("Content-Disposition", "inline; filename=" + videoID);
    output = response.getOutputStream();
    byte[] buffer = new byte[2096];
    int read;
    while ((read = input.read(buffer)) != -1) {
        output.write(buffer, 0, read);
    }
    output.flush();
    output.close();
}
