Embodiment Construction
[0065] In order to make the purpose, technical solution and advantages of the present application clearer, the implementation manners of the present application will be further described in detail below in conjunction with the accompanying drawings.
[0066] With the rapid development of cloud storage technology, video streams can be collected through multiple front-end devices, and the collected video streams can be uploaded to the cloud server in real time. During the process of real-time uploading of video streams, the cloud server may regularly update the video cover of each video stream, where the video cover is a video frame in the corresponding video stream. The client can obtain the video cover of each video stream updated in real time from the cloud server, and display the cover of each video for the user to browse to obtain the approximate content of the corresponding video stream. In order to allow the client to quickly and instantly extract the video cover, the clo...

The application discloses a video cover updating method, device and storage medium, belonging to the technical field of cloud storage. In this application, the front-end devices can collect video streams, and each front-end device has a device ID, and each device ID corresponds to a priority, that is, the priority can be set according to the importance of the video stream collected by the front-end device. Afterwards, the target video stream may be determined according to the priorities corresponding to the multiple device identifiers, and then the video cover of the target video stream may be updated. It can be seen that updating the video cover according to the priority can ensure to a greater extent that the updated video cover is the video cover of the more important video streams in a large number of video streams, because usually the user expects to obtain these more important video streams through the client. The video cover of the video stream, therefore, the acquisition success rate of the video cover in this solution is higher.
Description
technical field [0001] The present application relates to the technical field of cloud storage, in particular to a method, device and storage medium for updating a video cover. Background technique [0002] With the rapid development of cloud storage technology, video streams can be collected through multiple front-end devices, and the collected video streams can be uploaded to the cloud server in real time. During the real-time uploading of video streams, the cloud server can regularly update the video cover of each video stream. The video cover is determined according to the video frames in the corresponding video stream, and the client can obtain the real-time updated video of each video stream from the cloud server. Cover, and display the cover of each video for users to browse to get the general content of the corresponding video stream. [0003] In related technologies, the cloud server can receive a large number of video streams. In order to enable the client to quic...
