Kako strimovati video iz LAN a sa IP Camerom (Axis 211A)

[ bild-studio @ 27.12.2008. 07:06 ] @

Imam LAN mrezu na L2 Switch, Na koju su zakaceni racunari, IP Kamera (Axis 211A) i DSL Modem ( D - Link 360R ) sa kojim izlazim na net :). Konekcija je serovana ( Na Windows 2003 Serveru ) na sve racunare ukljucujuci IP kameru. Instaliran je DHCP tako da je IP kamere trenutno 192.168.0.169
Na serveru sam podigao Apache Server. I napravio malu skripticu (tacnije gotova) koja poziva kameru unutar LAN a i koja se nalazi u http://localhost/testing_streaming/index.php

Code:

<SCRIPT LANGUAGE="JavaScript">
// Set the BaseURL to the URL of your camera
var BaseURL = "http://192.168.0.169/";

// DisplayWidth & DisplayHeight specifies the displayed width & height of the image.
// You may change these numbers, the effect will be a stretched or a shrunk image
var DisplayWidth = "200";
var DisplayHeight = "200";

// This is the path to the image generating file inside the camera itself
var File = "axis-cgi/mjpg/video.cgi?resolution=640x480";
// No changes required below this point
var output = "";
if ((navigator.appName == "Microsoft Internet Explorer") &&
   (navigator.platform != "MacPPC") && (navigator.platform != "Mac68k"))
{
  // If Internet Explorer under Windows then use ActiveX
  output  = '<OBJECT ID="Player" width='
  output += DisplayWidth;
  output += ' height=';
  output += DisplayHeight;
  output += ' CLASSID="CLSID:DE625294-70E6-45ED-B895-CFFA13AEB044" ';
  output += 'CODEBASE="';
  output += BaseURL;
  output += 'activex/AMC.cab#version=4,1,4,4">';

  output += 'The AXIS Media Control, which enables you ';
  output += 'to view live image streams in Microsoft Internet';
  output += ' Explorer, could not be registered on your computer.';
  output += '<BR></OBJECT>';
} else {
  // If not IE for Windows use the browser itself to display
  theDate = new Date();
  output  = '<IMG SRC="';
  output += BaseURL;
  output += File;
  output += '&dummy=' + theDate.getTime().toString(10);
  output += '" HEIGHT="';
  output += DisplayHeight;
  output += '" WIDTH="';
  output += DisplayWidth;
  output += '" ALT="Online Streaming">';
}
document.write(output);
document.Player.ToolbarConfiguration = "play,+snapshot,+fullscreen"

// Remove the // below to use the code for Motion Detection.
  // document.Player.UIMode = "MDConfig";
  // document.Player.MotionConfigURL = "/axis-cgi/operator/param.cgi?ImageSource=0"
  // document.Player.MotionDataURL = "/axis-cgi/motion/motiondata.cgi";

Problem je sledeci:
- Kada dobijem javnu IP adresu npr. 77.222.21.52 i kada hocu sa druge IP adrese (ne iz mog LAN a) da pokrenem skriptu (http://77.222.21.52/testing_streaming/index.php), streaming naravno nece da se prikaze. A kad otvorim sa nekog racunara iz LAN a otvara se sto je i logicno. Znam sta je problem ali ne znam kako da ga otklonim.
- Kako da konkretno u Java Scripti ili PHP u kazem da je IP adresa 192.168.0.169 ( Lokalna adresa IP kamere ) a ne Javna adresa
- Ovo bih striktno radio sa ovom opremom, bez dodatnog ulaganja u router ili neki drugi hardverski element, posto znam da ukoliko postoji router postoji forwardovanje portova i IP adresa bla bla bla... Nisam strucnjak za Mreze :).
- Po mogucnosti da se problem rijesi na windowsovoj platformi.

Svaki savet bi mi dobrodosao :). Unaprijed zahvalan.
