iPhone can not play video from my web page (server)

Question

I am streaming video using NanoHTTPD from android device. Every device can play the video file in web page or using external media player except iPhone. Even Mac desktop can play the file too. I manually pushed the video file into iPhone and it's playable. So there is no issue about video format. When i click on the link iPhone open a video player (inside web page) and nothing happen.

I have solved my problem. After adding the range feature (can seek anywhere using player slider) iPhone can play the video.

private Response servePartialFile(String uri, Map<String, String> header,
                                      File file, String mime) {
        Response res;
        try {
            // Calculate etag
            String etag = Integer.toHexString((file.getAbsolutePath()
                    + file.lastModified() + "" + file.length()).hashCode());

            // Support (simple) skipping:
            long startFrom = 0;
            long endAt = -1;
            String range = header.get("range");
            if (range != null) {
                if (range.startsWith("bytes=")) {
                    range = range.substring("bytes=".length());
                    int minus = range.indexOf('-');
                    try {
                        if (minus > 0) {
                            startFrom = Long.parseLong(range
                                    .substring(0, minus));
                            endAt = Long.parseLong(range.substring(minus + 1));
                        }
                    } catch (NumberFormatException ignored) {
                    }
                }
            }

            // Change return code and add Content-Range header when skipping is
            // requested
            long fileLen = file.length();
            if (range != null && startFrom >= 0) {
                if (startFrom >= fileLen) {
                    res = createResponse(Response.Status.RANGE_NOT_SATISFIABLE,
                            NanoHTTPD.MIME_PLAINTEXT, "");
                    res.addHeader("Content-Range", "bytes 0-0/" + fileLen);
                    res.addHeader("ETag", etag);
                } else {
                    if (endAt < 0) {
                        endAt = fileLen - 1;
                    }
                    long newLen = endAt - startFrom + 1;
                    if (newLen < 0) {
                        newLen = 0;
                    }

                    final long dataLen = newLen;
                    FileInputStream fis = new FileInputStream(file) {
                        @Override
                        public int available() throws IOException {
                            return (int) dataLen;
                        }
                    };
                    fis.skip(startFrom);

                    res = createResponse(Response.Status.PARTIAL_CONTENT, mime,
                            fis);
                    res.addHeader("Content-Length", "" + dataLen);
                    res.addHeader("Content-Range", "bytes " + startFrom + "-"
                            + endAt + "/" + fileLen);
                    res.addHeader("ETag", etag);
                }
            } else {
                if (etag.equals(header.get("if-none-match")))
                    res = createResponse(Response.Status.NOT_MODIFIED, mime, "");
                else {
                    res = createResponse(Response.Status.OK, mime,
                            new FileInputStream(file));
                    res.addHeader("Content-Length", "" + fileLen);
                    res.addHeader("ETag", etag);
                }
            }
        } catch (IOException ioe) {
            res = createResponse(Response.Status.FORBIDDEN,
                    NanoHTTPD.MIME_PLAINTEXT, "FORBIDDEN: Reading file failed.");
        }

        return res;
    }
