C#视频动画播放控制策略

Control strategy of video playback in C#

针对C#语言中常用播放控制方法在视频动画的逆序及自定义播放时存在的较大问题,提出一种利用C#语言定义新视频文件、播放控制文件的方法。该方法创建继承于PictureBox的播放控件,从而轻松控制正序、逆序、自定义顺序播放及播放速度,可以使用简单的视频动画源(帧总数少)实现较为复杂的视频效果。实验结果表明,所设计的播放控制方法方便快捷,播放速度达到日常视频软件的播放水平,视频大小可任意缩放,正序、逆序可自由控制,可适用绝大多数视频播放项目的要求。

Aimed at the problem of the reverse and custom frame playback by common method in C# language,a new method is put forward,which defined a new video file and a playback control file.This method may easily support normal playing,reverse playing,custom playing and playing speed using a control that inherited from PictureBox,and it can use a simple video animation source（the number of frames is less） to achieve a more complex video effects.Experiments show that the playing speed of the method,which is convenient and efficient,is normal and the size of video can be adjusted.So this method applies to almost of projects about video playing.
