We need program module, which can:

* capture snapshots from web-camera (as BMP or JPG image);

* capture video stream from web-camera and pass data captured after some interval (e.g. 1 second) to main application via some callback interface;

* provide interface for displaying data obtained in p.2 above on some window.

Requirements:

* compatible with Windows 2000/XP/2003/Vista/2008/R2/7, both 32 and 64 bit;

* do not use GPL or LGPL components; or large 3rd party libraries/components;

* preferred: use only standard interfaces, like DirectX; do not use VfW.

* the module should be realized as dynamic library written and compiled with Visual C++ or Borland C++ Builder or Delphi.

* Module should provide option to select a source (i.e. use one selected web-camera from several installed on computer);

* capturing module should not display any dialogs, prompts or messages. All error reporting and other communication should be made with main program only via some API;

* do not create intermediate files in the process of capturing, at least warn us in your bid if these files are required, and what files and where will be created.

API of the module created should be simple and easy to use, for example as follows:

void Initialize( pointer to callback function for error reporting);

int StartCapture(DWORD CameraID, pointer to some callback function for data transfer)

StopCapture(CameraID)

GetSnapshot(CameraID, LPBYTE data, DWORD cbData)

DisplayCapture(HWND wnd, LPBYTE data, DWORD cbData)
