视频编解码器

代码说明：

应用背景 This is the second public release of our MPEG-2 encoder. It converts an   ordered set of uncompressed input pictures into a compressed bitstream   compliant with ISO/IEC 13818-2 DIS [1] (MPEG-2).   This program will evolve to become: ISO/IEC 13818-5 Software Simulation   of MPEG-2 Systems, Video, and Audio. 关键技术  The execution template for the encoder is:       mpeg2encode parameter_file output.m2v   Coding parameters can be modified by editing the parameter_file. Since the   parser expects the operating parameters to be on certain line numbers,   kindly do not insert or delete lines from the file.   We have provided a couple of sample parameter files in the par directory. &nb
