执行此操作的代码，对于不熟悉C ++的人来说可能看起来并不简单。



从显示视频的示例开始，然后尽可能地实现这些方法。逐步调整样本以达到你想要的效果。



如果你有任何具体问题，请回来。

Code to do this, likely won''t seem simple to someone who is new to C++.

Start with a sample that displays video, and then implement those methods the best you can. Incrementally adapt the sample to do what you want.

Come back if you have any specific issues along the way.
