Abstract: Embodiments of the present disclosure disclose a method and apparatus for recommending a video. A specific implementation of the method includes: finding a recommended video corresponding to a target video from all candidate videos based on similarities of content characteristics of the videos, the target video being a video to be played on a terminal of a user; and sending play information of the recommended video corresponding to the target video to the terminal of the user. The method finds a video similar on video content to the target video that the user desires to view based on the content characteristic of the video, and recommends the video similar on video content to the target video that the user desires to view to the user.

Abstract: Disclosed is a method and device for switching video streams. The method comprises: acquiring video streams of a video in response to receiving a playback request for the video sent by a terminal, the video streams comprising: a video stream with a first group of pictures (GOP) frame number and a video stream with a second GOP frame number; sending the video stream with the first GOP frame number to the terminal, searching for a third key frame in the video stream with the first GOP frame number, and extracting a decoding time stamp (DTS) of the third key frame; searching the video stream with the second GOP frame number for a frame having an identical DTS; determining whether the frame is a fourth key frame in response to finding the frame having the identical DTS; and sending the video stream with the second GOP frame number to the terminal.
