ActiveX control for Video Streaming

We would like to develop an ActiveX control which can be used on Web Browser and Windows Applications. ActiveX control receives Video Streaming from TCP/HTTP video server, parses the video, decodes the image if it needed, and displays video on control. See Figure 1 HTTP Video Server is not implemented yet. The streaming format should be as same as TCP streaming, and the request would come from ASPX URL with additional encrypted parameters. We require the project include HTTP request from ActiveX control. TCP Video Server was written with VB.NET socket. We have example code in a VB.NET windows application on requesting, receiving, parsing, decoding and drawing. You are required to connect to TCP server with VC++ socket. TCP video server includes more than one camera on most of the case. ActiveX Control may request more than one camera, and all cameras video will combine to one video streaming to client (ActiveX). The camera number is embedded in the streaming, so you can know an image belong to which camera after parsing. Each camera will be displayed in different location on the ActiveX control. We have example code in VB.NET, and will discuss this later. The request from ActiveX control includes IP Address of TCP Server, Port Number, User Name, Password, video compression format, and the list of camera number that client wants. All of the parameters are encrypted and passed from either Web Brower or Windows Application. You may need to send request to multiple TCP video servers, and you need to create one thread per TCP server in ActiveX control. We have example code with VB.NET. When the TCP or HTTP connections break for whatever reasons, the ActiveX Control will try to re-connect to server. ## Deliverables **UI Design** The interface of the ActiveX control would be like this: See Figure 2 The top, bottom, left and right margins are adjustable during design mode and running mode, so we can add logo or other controls later. When the whole ActiveX control resize, the Display Area (Grid) would resize to fit whole ActiveX control minus the margin area. Each camera location and size will also change to adjust ActiveX Control changes. The camera location and size are calculated from grid ID and camera location in the grid. We have example code in VB.NET. We should have the ability to add extra label or text on the area of each camera, so we can write camera name or say the connection was broken etc. You should choose a fast and reliable method to draw images on the screen. When we refresh the Control, the image should stay. Paint images on the control should not take too much CPU utilization. **Class Interface** The ActiveX control should include the following interface, all other interfaces can be added later without much difficulty. We will discuss the final interfaces during design phase. 1. Standard COM interface. 2. SetMargin(top as integer, left as integer, right as integer, bottom as integer) Also need property of the margins. The default margins are zero. 3. SetSize(width as integer, height as integer) Also need property of the Size. As we talked earlier, the grid area and each camera area should be adjusted per new size. In <**object>** tag of the HTML file, <**height**> and <**width**> parameter should have same effort as calling **SetSize**() . 4. SetParameters(parameter as string) Also need the property for parameter. The parameter is an encrypted string, you can decrypt it inside the class, and split string into IP address, Port, UID, Password, GridID, CameraList etc. The SetParameter also trigger the new worker threads start. 5. SetLabel() This can be a private function, and draw string and label per requirement. We can discuss this later for more details. 6. Class should implement dispose method to release all resources during close. 7. Refresh method. 1) The ActiveX will be written with Visual C++ 6.0. 2) We own source code. The designer cannot release the source code and ActiveX control to 3rd party. 3) Reliability 4) Quality 5) Finish the project on time. 6) Need demo program in ASP.NET and windows application. 7) Create setup application for windows application 8) Create Cab file for Internet Explore auto setup. 9) Help us to Digital Sign ActiveX control. 10) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 11) Deliverables must be in ready-to-run condition, as follows (depending on the nature of the deliverables): a) For web sites or other server-side deliverables intended to only ever exist in one place in the Buyer's environment--Deliverables must be installed by the Seller in ready-to-run condition in the Buyer's environment. b) For all others including desktop software or software the buyer intends to distribute: A software installation package that will install the software in ready-to-run condition on the platform(s) specified in this bid request. 3) All deliverables will be considered "work made for hire" under U.S. Copyright law. Buyer will receive exclusive and complete copyrights to all work purchased. (No GPL, GNU, 3rd party components, etc. unless all copyright ramifications are explained AND AGREED TO by the buyer on the site per the coder's Seller Legal Agreement). ## Platform Windows 98, Windows 2000, Windows XP, 2003 Server and future OS Works with Internet Explore 4.0 and Firefox web browser.
