Description: 银行的数字化监视监控系统是目前比较有市场及应用前景的开发项目，基于不同的MPEG采集卡与硬件外围设备开发的监视监控系统在国内外都有比较成型的技术。为了满足实时监视、实时采集压缩、随时回放、压缩数据流的传播等具体要求，在该系统中使用了一种用于网络视频/音频多点传输（视频广播）的视频数据采集卡，提供AVI（MPEG
I Frame压缩编码）采集、MPG采集。发送端广播MPEG流，接受端接受MPEG流并显示，网络传输采用WinSock 2
IP-Multicast。如果本机为发送端，网络上另外任何一台PC可以作为接收端。只要指定不同端口号，同时可以有多台PC机作为发送端，多台PC机作为接收端接收不同发送端的视频数据，也可在传送数据的同时在本机将数据存为MPEG文件。本文主要介绍在VB的环境下开发MPEG卡采集的Audio/Video数据播放的一些编程技巧。

Description: 利用Visual C++实现AVI文件的图像截取，
AVI文件就是我们所说的多媒体文件，所谓的AVI图像就是视频图像，该文件是一个RIFF说明文件，它用于获取、编辑、演示音频、视频序列。一般的AVI文件包含音频流和视频流，有的特殊的AVI还包含一个控制路径或MIDI路径作为附加的数据流。

Description: 微软的音频/视频交错（AVI）文件格式是一种RIFF格式的文件规范与应用，捕捉，编辑使用和播放音频/视频序列。一般情况下，AVI文件包含了不同类型的数据多个流。大多数AVI序列将同时使用音频和视频流。一个简单的AVI序列变异使用视频数据，不需要音频流。专门阿维序列可能包括控制赛道作为额外的数据流或MIDI音轨。控制轨道可以控制，如一个MCI光碟机的外部设备。在MIDI轨道可以发挥的顺序的背景音乐。虽然专门序列需要专门的控制程序，利用它的全部功能，应用程序，可以阅读和发挥阿维序列仍然可以阅读和发挥在专门的AVI文件序列的优势。 （这些应用程序忽略了非专门文件阿维数据。）本章主要介绍AVI文件只包含音频和视频数据。
本章涵盖以下主题：
• 一个AVI文件所需的块
• 一个AVI文件可选的数据块
• 制定程序写入AVI文件
有关RIFF格式文件的其他信息，请参阅Microsoft Windows多媒体程序员指南和Microsoft Windows多媒体程序员参考。
有关安装的压缩机及解压缩的其他信息，请参见第10章“视频压缩和解压驱动程序。”-The Microsoft Audio/Video Interleaved (AVI) file format is a RIFF file specification used with applications that capture, edit, and playback audio/video sequences. In general, AVI files contain multiple streams of different types of data. Most AVI sequences will use both audio and video streams. A simple variation for an AVI sequence uses video data and does not require an audio stream. Specialized AVI sequences might include a control track or MIDI track as an additional data stream. The control track could control external devices such as an MCI videodisc player. The MIDI track could play background music for the sequence. While a specialized sequence requires a specialized control program to take advantage of all its capabilities, applications that can read and play AVI sequences can still read and play an AVI sequence in a specialized file. (These applications ignore the non-AVI data in the specialized file.) This chapter primarily describes AVI files containing only audio and vide

Description: VFW(Video for Windows)函数是Windows环境下实现视频捕获的重要工具，是Windows操作系统增设的视频服务库。由于VFW函数可以方便地实现视频、音频数据流到AVI文件的存储，在Visual C++中也将VFW函数称为AVICAP窗口类函数。AVICAP窗口类为应用程序提供了一个基于访问视频采集硬件的、基于消息的接口，从而使之能访问视频和波形文件，能灵活的实现从模拟视频源采集数字视频信号，并将所捕获的视频流存储到磁盘或直接对视频缓存进行处理。-VFW (Video for Windows) function is a Windows environment, an important tool for video capture is the Windows operating system, library of additional video services. Because the function can be easily achieved VFW video and audio data stream to AVI file is stored in the Visual C++ will also function as AVICAP VFW window class function. AVICAP window class provides applications access the video capture of a hardware-based, message-based interface, so that it can access video and waveform files can be a flexible source capture analog video from a digital video signal, and the video captured stream is stored to disk or directly to the video buffer for processing.

-Some approaches to detect motion in a video stream. There are many approaches for motion detection in a continuous video stream. All of them are based on comparing of the current video frame with one from the previous frames or with something that we ll call background. In this article, I ll try to describe some of the most common approaches. In description of these algorithms I ll use the AForge.NET framework, which is described in some other articles on Code Project: [1], [2]. So, if you are common with it, it will only help. The demo application supports the following types of video sources:* AVI files (using Video for Windows, interop library is included) * updating JPEG from internet cameras * MJPEG (motion JPEG) streams from different internet cameras * local capture device (USB cameras or other capture devices, DirectShow interop library is included).

Description: DirectShow是微软公司在ActiveMovie和Video for Windows的基础上推出的新一代基于COM(Component Object Model)的流媒体处理的开发包，与DirectX开发包一起发布。DirectShow使用一种叫Filter Graph的模型来管理整个数据流的处理过程，运用DirectShow，我们可以很方便地从支持WDM驱动模型的采集卡上捕获数据，并且进行相应的后期处理乃至存储到文件中。这样使在多媒体数据库管理系统(MDBMS)中多媒体数据的存取变得更加方便。它广泛地支持各种媒体格式，包括Asf、Mpeg、Avi、Dv、Mp3、Wave等，为多媒体流的捕捉和回放提供了强有力的支持。(DirectShow is Microsoft Corp's ActiveMovie and Video for Windows based on the launch of a new generation of COM (Component Object Model) streaming media development package, and DirectX development kits released together. The process, DirectShow uses a Filter Graph model to manage the entire data stream using DirectShow, we can easily drive the model from the support WDM card to capture data, and the corresponding post processing and storage to a file. As a result, access to multimedia data becomes more convenient in a multimedia database management system (MDBMS). It supports a wide variety of media formats, including Asf, Mpeg, Avi, Dv, Mp3, Wave and so on. It provides strong support for the capture and playback of multimedia streams.)
