ONVIF致力于通过全球性的开放接口标准来推进网络视频在安防市场的应用，这一接口标准将确保不同厂商生产的网络视频产品具有互通性。2008年11月，论坛正式发布了ONVIF第一版规范——ONVIF核心规范1.0。随着视频监控的网络化应用，产业链的分工将越来越细。有些厂商专门做摄像头，有些厂商专门做DVS，有些厂商则可能专门做平台等，然后通过集成商进行集成，提供给最终客户。这种产业合作模式，已经迫切的需要行业提供越来越标准化的接口平台

目前网上视频聊天软件、视频会议软件、可视IP电话软件随处可见，你是否想自己做一个玩玩？其实这类软件无非是视频加上网络而建成的。如果熟悉视频捕捉和网络传输技术，根本就难不倒你。微软为软件开发人员提供了一个专门用于视频捕捉的VFW SDK（Video for Windows SDK），用它实现视频捕捉很简单，至于网络传输嘛，Delphi更是提供了N多种网络组件，随你用了。本文详细介绍了如何利用Delphi中开发视频聊天软件，同时给出了两个程序示例

ONVIF规范描述了网络视频的模型、接口、数据类型以及数据交互的模式。并复用了一些现有的标准，如WS系列标准等。 ONVIF规范的目标是实现一个网络视频框架协议，使不同厂商所生产的网络视频产品（包括摄录前端、录像设备等）完全互通。 ONVIF规范描述了网络视频的模型、接口、数据类型以及数据交互的模式。并复用了一些现有的标准，如WS系列标准等。 ONVIF规范的目标是实现一个网络视频框架协议，使不同厂商所生产的网络视频产品（包括摄录前端、录像设备等）完全互通。 ONVIF规范中设备管理和控制部分所定义的接口均以Web Services的形式提供。ONVIF规范涵盖了完全的XML及WSDL的定义。每一个支持ONVIF规范的终端设备均须提供与功能相应的Web Service。服务端与客户端的数据交互采用SOAP协议。 ONVIF中的其他部分比如音视频流则通过RTP/RTSP进行 。 协同性：不同厂商所提供的产品，均可以通过一个统一的“语言”来进行交流。方便了系统的集成。 灵活性：终端用户和集成用户不需要被某些设备的固有解决方案所束缚。大大降低了开发成本。 质量保证：不断扩展的规范将由市场来导向，遵循规范的同时也满足主流的用户需求。 由于采用WSDL+XML模式，使ONVIF规范的后续扩展不会遇到太多的麻烦。XML极强的扩展性与SOAP协议开发的便捷性将吸引到更多的人来关注和使用ONVIF规范。 ONVIF的组织日益壮大，与同领域的PSIA，HDCCTV相比，占据了绝对的人员优势。会员企业不乏国内外著名的设备制造商与集成商。一套规范、协议的生命周期，与市场占有率是息息相关的。而ONVIF规范的发展则正是由市场来导向，由用户来充实的。每一个成员企业都拥有加强、扩充ONVIF规范的权利。ONVIF规范所涵盖的领域将不断增大。目前门禁系统的相关内容也即将被纳入ONVIF规范之中。 在安防、监控系统急速发展的今天，效率和质量的领先所带来的价值不言而喻。ONVIF协议提供了这样的潜质

See EdsImageInfo definition of EDSDKType.pas Parameters: In: inImageRef - The reference of the image. inImageSource - Specfies kind of image - thumbnail, preview, fullview Out: outImageInfo - Infomaiton of the image.

Returns uncompressed results for JPEGs and processed results in the designated pixel order (RGB, Top-down BGR, and so on) for RAW images. Additionally, by designating the input/output rectangle, it is possible to get reduced, enlarged, or partial images. However, because images corresponding to the designated output rectangle are always returned by the SDK, the SDK does not take the aspect ratio into account. To maintain the aspect ratio, you must keep the aspect ratio in mind when designating the rectangle. Parameters: In: inImageRef : The reference of image object inImageSource : Specfies kind of image - thumbnail, preview, fullview inImageType : Specifies image type ID number inSrcRect : Rectangle of the source image inDstSize : Designate the rectangle size for output.

When saving with JPEG compression, the JPEG quality setting applies with respect to EdsOptionRef. Parameters: In: inImageRef : The reference of image inImageType : Specifies image format ID number inSaveOption : Specifies save option Out: outStreamRef : The reference of file stream Returns: Returns EDS_ERR_OK if successful.

Creating the cache increases the processing speed, starting from the second time. Parameters: In: inImageRef - The reference of the image. inUseCache - Whether cache image data , If TRUE, cache image. If FALSE, the cached image data will released.

Returns: Any of the sdk errors. -----------------------------------------------------------------------------} function EdsCreateEvfImageRef ( inStreamRef : EdsStreamRef; var outEvfImageRef : EdsEvfImageRef ) : EdsError; stdcall; external edsdk; {----------------------------------------------------------------------------- Function: EdsDownloadEvfImage Description: Downloads the live view image data set for a camera currently in live view mode. Live view can be started by using the property ID:kEdsPropertyID_Evf_OutputDevice and data:EdsOutputDevice_PC to call EdsSetPropertyData. In addition to image data, information such as zoom, focus position, and histogram data is included in the image data set. Image data is saved in a stream maintained by EdsEvfImageRef. EdsGetPropertyData can be used to get information such as the zoom, focus position, etc. Although the information of the zoom and focus position can be obtained from EdsEvfImageRef, settings are applied to EdsCameraRef. Parameters: In: inCameraRef - The Camera reference. In: inEvfImageRef - The EVFData reference.
