Opencv VideoCapture: : read has not returned, blocking

I pulled the string out of the camera, the code still stay in the position of the read, will not return,

While (the capture. Read (frame)) {

I also encountered the same problem (namely VideoCapture: : read () has been blocked), however I found in a video file, read again, is normal,
