Description: 在DCT域中，通过裁减高频分量，或者增加高频分量的方式，对图像视频序列的尺寸进行上/下变换，变换过程中其他的低频DCT系数也要做相应的调整，否则处理后图像亮度会与原图不一致-resizing the video/image in dct domain .Adding or removing the high frequency components will realize the up-resizing or down-resizing. extra attention need to on the orignal low frequency. because the luminance have connection with the low frequency components.

Description: 该模块能对视频分辨实时缩放，采用最近邻域和双线性差值算法。该模块可以实时配置输入输出的分辨率、缩放因子，缩放算法类型等参数，也可在编译时采用默认配置。-The Video Stream Scaler (streamScaler) performs resizing of video streams in a low latency manner, resizing with either bilinear or nearest-neighbor modes.The core offers runtime configuration of input and output resolution, scaling factors, and resize type. Data width, color channels and maximum video resolution can be configuredat compile time.

Description: 最新的FFMPEG编解码库，适合多种音视频文件的编解码-ffmpeg is a very fast video and audio converter that can also grab from
a live audio/video source. It can also convert between arbitrary sample
rates and resize video on the fly with a high quality polyphase filter.

Description: 用于多媒体视频流的缩放处理,适用于Win32-Dshow平台;
允许动态选择算法(双线性重采样算法,双立方重采样算法,汉宁窗重采样算法);
双线性重采样算法和双立方重采样算法都经过SSE2指令加速(C代码内嵌汇编);(For the multimedia video stream scaling processing, suitable for Win32-Dshow platform;
Allowing the dynamic selection algorithm (bilinear resampling algorithm, bicubic resampling algorithm, Hann window resampling algorithm);
Both the bilinear resampling algorithm and the bicubic resampling algorithm are accelerated by the SSE2 instruction (C code embedded assembly);)
