使用FFMPEG库进行视频解码，然后在一个Static控件上使用SDL2.0进行视频显示，相比SDL1.0,2.0版本支持多窗口同时显示，性能也大幅提升。（demo中未处理音频帧）。本Demo优点：将视频解码和显示分别封装了两个类CFfmpegDecod和CSdlShow，便于学习和理解播放流程。适合学习者使用。(Using the FFMPEG library for video decoding, and then on a Static control on the use of SDL2.0 video display, compared to the SDL1.0,2.0 version supports multi window at the same time, performance is also greatly improved. (demo is not processed for audio frames). The Demo advantages: the video decoding and display are encapsulated in two classes CFfmpegDecod and CSdlShow, easy to learn and understand the playback process. Suitable for learners to use.)
