- 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
video_stream_scaler
- 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 run
ffmpeg-1.2.tar
- 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.
