Westi Posted September 6, 2009 Share Posted September 6, 2009 Many IP cameras need to install an ActiveX component (i.e. "VatDec.cab" includes VATDecoder.dll) to view the livevideostream.The camera's internal server creates a script like this:<script language=Javascript>if ((navigator.appName == "Microsoft Internet Explorer")&&(navigator.platform != "MacPPC")){document.write("<OBJECT ID=\"VAtCtrl\" WIDTH=362 HEIGHT=310 name=\"VAtCtrl\"");document.write("CLASSID=CLSID:210D0CBC-8B17-48D1-B294-1A338DD2EB3A");document.write("CODEBASE=\"http://111.111.111.111/VatDec.cab#version=1,0,0,50\">"); document.write("<PARAM NAME=\"Url\" VALUE=\"http://111.111.111.111/cgi-bin/control.cgi\">");document.write("<PARAM NAME=\"VSize\" VALUE=\"SIF\">");document.write("<PARAM NAME=\"Language\" VALUE=\"en\">"); document.write("<PARAM NAME=\"Deblocking\" VALUE=\"true\">");document.write("<PARAM NAME=\"DisplayTimeFormat\" VALUE=\"1\">");document.write("<PARAM NAME=\"DigitalZoomEnableChk\" VALUE=\"true\">");document.write("<PARAM NAME=\"DigitalZoomEdit\" VALUE=\"true\">");document.write("</OBJECT>"); }</SCRIPT>111.111.111.111 is only an example for camera's IPNeeded TypeLibrary of VATDecoder.dll is:_IVitaminCtrlEvents InterfaceInterface GUID={AAFC5C2B-889A-41BB-8BB7-982AF0B53E29};VatCtrl ClassClass GUID={210D0CBC-8B17-48D1-B294-1A338DD2EB3A};IVatCtrl InterfaceInterface GUID={00595B6A-41B8-481D-BBA3-9E860322FCA1}; function GetIDsOfNames(riid:^GUID; rgszNames:^^I1; cNames:UINT; lcid:UI4; out rgdispid:^I4); function Invoke(dispidMember:I4; riid:^GUID; lcid:UI4; wFlags:UI2; pdispparams:^DISPPARAMS; out pvarResult:^variant; out pexcepinfo:^EXCEPINFO; out puArgErr:^UINT); property-get & put Url: BSTR; property-get & put RemoteIPAddr: BSTR; property-get & put CurrentControlCam: I4; property-get & put GetMDParmUrl: BSTR; property-get & put SetMDParmUrl: BSTR; property-get & put MDEditMode: bool; property-get & put ClickEventHandler: EClickEventHandler; property-get & put WheelEventHandler: bool; property-get & put DigitalZoomEdit: bool; property-get & put DigitalZoomEnableChk: bool; property-get & put RemoteID: I4; property-get & put VSize: BSTR; property-get & put ControlPort: I4; property-get & put Language: BSTR; property-get & put Stretch: bool; property-get & put Deblocking: bool; property-get & put UserDateFormat: bool; property-get & put DisplayTimeFormat: EDisplayTimeFormat; property-get & put ControlType: EControlType; property-get & put DisplayErrorMsg: bool; property-get & put ConnectionProtocol: EConnProtocol; property-get & put MediaType: EMediaType; property-get AudioBitRate: I4; property-get FrameRate: I4; property-get VideoBitRate: I4; property-get & put ReadSettingByParam: bool; property-get & put IgnoreBorder: bool; property-get & put IgnoreCaption: bool; property-get & put DisplayMotionFrame: bool;My steps for now to create my own gui:1. create embedded ActiveX-Gui with controls and object "VATDecoder.VatCtrl.1"2. copied VATDecoder.dll to systemdir and registerHow to call/submit the needed parameters to VATDecoder.dll and "VATDecoder.VatCtrl.1" Link to comment Share on other sites More sharing options...
