Abstract

Embodiments of the invention disclose a video playback method and a related device. The method comprises the steps that a monitor storage device acquires video data of a to-be-playback video accordingto a video playback request of a client, determines first GOP data as video playback data and determines OSD data corresponding to the nth GOP data as video playback data when determining that a dynamic monitor result of the nth GOP data is a first indicator, or, determines the nth GOP data as video playback data, and sends the video playback data to the client. The monitor storage device can determine corresponding video playback data according to the dynamic detection result of the GOP data, when an image does not change according to comparison of the nth GOP data and previous GOP data, theGOP data of small data amount is sent, so that transmitted data in video playback is reduced effectively, the decoding pressure of the client is relieved, and the system resource of the client is saved.

Description

technical field [0001] The invention relates to the technical field of video monitoring, in particular to a video playback method and related devices. Background technique [0002] In the field of video surveillance, the collection, storage and playback of surveillance video are usually completed by different devices. The monitoring front-end equipment is responsible for collecting the monitoring video, and sending the encoded video data to the monitoring storage device, which stores the video data and responds to the playback request of the client. When the client requests to playback the surveillance video within a certain period of time, the surveillance storage device will send the video data of the surveillance video to the client, and the client will decode and play the video data. However, in the prior art, when a client requests playback of a surveillance video within a certain period of time, the surveillance storage device will send all video data of the surveilla...
