采用DirectDraw的H264解压缩源代码和YUV视频播放源代码
从FFMPEG中摘录出来并且调试通过的H264解码的源代码(c文件),没使用FFMPEG编译出来的lib和dll库,可以直接在VS2010环境下单步调试以跟踪解压缩的所用过程细节，对于想学习和掌握H264编解码的标准的同学们非常有用.
读取h264格式的文件并进行实时解压缩和播放,解压缩后的图像格式是YUV,在一个对话框的控件中逐帧显示，程序在VS2010下编译链接通过,可直接使用.
视频播放是采用窗口式的基于DirectDraw方法，基于DirectDraw的图像播放是Windows平台下很高效的方法，已经封装成CDirectDraw类，可以很方便地直接应用到别的图像和视频处理工程中。
使用时打开h264文件或yuv文件（工程中有test.h264,encode.h264和FOREMAN_176x144_15.yuv三个测试文件），单击[Play File]即可进行播放，播放的帧率可以更改定时器时间调整。可以很方便的更改图像的宽度和高度以便播放不同分辨率的视频。
