videowatermarkDCT

代码说明：

  一个基于DCT系数的视频水印嵌入程序，读取yuv文件，提取其中的若干帧，然后对每帧做DCT变换，在中低频修改系数值，然后做IDCT，再把每帧图像组成YUV格式播放。(DCT coefficients of a video-based watermark embedding program, read the yuv file, extract the number of frames, and then do each frame DCT transform coefficients in the low-frequency changes, then do IDCT, then each frame component YUV format player.)
