首先,让我们来看一下videocapture capture = new videocapture(url)的基本用法。在这个表达式中,我们使用了一个url参数来指定要捕获的视频源。这个url可以是一个本地视频文件的路径,也可以是一个网络视频流的地址。通过这个表达式,我们创建了一个videocapture对象,它将用于后续的视频捕获操作。 一旦我们创建了videocapture...

VideoCapture 读入视频的方法有两种:①先实例化再初始化:VideoCapture capture;capture.open("C:/Users/齐明洋/Desktop/1.mp4")②实例化的同时进行初始化 VideoCapture capture("C:/
