VC++实现AVI文件的图像截取,Cavi类中的pData缓冲区存放AVI文件中的具体某一帧图像数据，同时Cavi类的m_pBMI为BMP图像文件信息结构，这时可以根据图像的大小定义BMP图像文件头结构-VC AVI file image interception, Cavi type of buffer storage pData AVI file of a specific frame image data, while the m_pBMI Cavi type of BMP image f

基于frame buffer的图像数据采集程序。涉及到framebuffer 、v4l等常用驱动，是个不错的学习材料。-frame buffer based on the image data collection procedures. Related to the framebuffer v4l popular driver is a good learning materials.

Camera Interface模块是视频输入转换存储模块。该模块一端接通用的video camera设备，另一端接AHB总线。实现了将Camera捕捉到的数据进行转换、并通过DMA存储到memory中。该IP支持ITU-R BT 601/656 8-bit 模式。支持YCbCr, RGB格式输入。可以将camera产生的YCbCr信号转换成24bit RGB 信号，然后下采样生成16bit RGB 5：6：5的LCD能直接读取显示的数据。该设备支持图像的镜像和翻转，以便适应手持式设备在移动环境

基于opencv的视频读入程序，可以从摄像头采集视频，将每帧暂时存入临时缓冲区并显示，为视频处理的基础程序块-Opencv video-based reading program, you can capture video from a camera will be temporarily deposited in the temporary buffer for each frame, and show that the basis for the video processing bloc

Implementation of a speech codec based on coding of speech at 8 kbit/s using conjugate-structure algebraic-code-excited linear-prediction (CS-ACELP) - We took .wav files that is sampled at 8000 Hz using 16-bit linear PCM. The encoding process i
