Hi webjimmy,

You can dymanic display omnicast Video/camera in the web site very easily. The Video isn't an Avi, GxVideolive decodes and render the native video stream that comes from the camera.

Omnicast has a SDK that includes a series of ActiveX.GxvideoLive is one of them.

Normally if you have the SDK Documentation and installation, it has a nice sample to shows how to use GxVideoLive in a WebLive.

Here's a quick overview of waht you have to do.

First you need 2 activeX components. GxVideoLive and GxUIProxyWeb.

Here are VB samples:

How to create GxUIProxy and GxVideoLive:

Code:

<object id="GxUIProxy" classid="clsid:C62E8E18-82A4-4bc8-8E10-4B1F27E1DCB8" VIEWASTEXT></object>
<object id="GxVideoLive" style="LEFT: 0px; WIDTH: 300px; TOP: 0px; HEIGHT: 200px" classid="clsid:E10F54C4-7191-4da8-A254-43F92E383C10" VIEWASTEXT></object>

Then we must link the GxUIProxy with GxVideolive:

Code:

GxUIProxy.CreateInstance
GxVideoLive.CreateInstance GxUIProxy

The UIProxy activex must authenticate to the Omnciast Directory server. The code will display a logon dialog.

Code:

Dim szUserName, szPassword, szDirectory, nBlockingMode

szUserName  = window.txtUserName.value
szPassword  = window.txtPassword.value
szDirectory = window.txtDirectory.value 
nBlockingMode = 1

On Error Resume Next

GxUIProxy.LogOn szDirectory, szUserName, szPassword, CBool (nBlockingMode)
If Err.Number <> 0 Then
    MsgBox Err.Description, , "LogOn Error"
End If

Once the UIProxy is logon, you just have to specify which camera you want to see in the GxVideoLive ActiveX.

Code:

GxVideoLive.StartLiveVideo strCameraGUID

To see more than one camera at a time, you can instantiate more than 1 GxVideoLive using a single GxIUProxy object.

To find out camera GUID, GxIUProxy give methods to convert from a Logical ID (Simple number from 1 to XXXX) to a GUID. Omnicast assigns automatically a logical ID to each camera.

I hope it helps!
