由于在Windows2000下右键点击RIFF (*.avi,*.wav) 类型的文件，在摘要里没有该文件的具体信息，所以我就编了一个小程序，用来显示该类型文件的信息。具体信息主要包含视频流和音频流信息。视频流信息主要有:(1)Total frames (2)Frame rate (3)Codec (4)视频的宽度和高度等。音频信息主要有:(1)音频的格式 (2)单声道还是立体声 (3)采样频率等。-in Windows2000 Right click RIFF (*. avi, *. wav) file types, in a summary of the document was not specific information, so I compiled a small program used to indicate the type of document information.
