推荐答案

老问题，但我希望这可以帮助别人（同这里我的答案）

Old question, but I hope this can help someone (same as my answer here)

OpenCV的期望一个文件扩展名的VideoCapture的说法，   即使1并不总是必要的（如在你的情况）。

OpenCV expects a filename extension for its VideoCapture argument, even though one isn't always necessary (like in your case).

您可以欺骗它通过传递在其结束一个虚拟参数    MJPG 扩展：

You can "trick" it by passing in a dummy parameter which ends in the mjpg extension:

因此​​，也许尝试：

VideoCapture vc;
ipCam.open("http://MyIP:port/videofeed/?dummy=param.mjpg")
