Abstract
Disclosed is a video switching method, a device, and a video patrol system. The method comprises: receiving a video switching instruction to determine a display device corresponding to a to-be-played video; determining whether there is a currently played video in the determined display device; if so, determining a task identifier corresponding to the currently played video; closing the currently played video according to the task identifier; and sending the video to be played to the display device for playing. When the video played in the display device needs to be switched, the task identifier corresponding to the currently played video in the display device is determined first, and the video is closed according to the task identifier. Then, the to-be-played video is sent to the display device for playing. This shows that the currently played video is normally shutdown, thereby avoiding an unknown error caused by abnormal closing of the video.
