在OpenCV视频捕获上使用cvLine

Question

I have been able to stream video but what I would like to do is use cvLine to draw a line on the video as it is being recorded. Is there anyway to do this? cvLine seems to only work on static images. Any help would be greatly appreciated.

您将必须捕获每个帧，在其上绘制任何内容，并根据需要执行任何其他处理，然后保存处理后的结果帧。
