Problems solved by technology

[0003] However, because the screen projection technology is limited to the local area network, long-distance screen projection playback and control cannot be realized. When the area of ​​public places such as shopping malls is large, the data transmission distance of the LAN is relatively short, and the merchants cannot use the screen projection technology. Put the advertising video on a huge number of playback terminals in the shopping mall for output and playback, and at the same time, it is impossible to centrally control the playback of the advertising video in each playback terminal. Obviously, this kind of projection technology can only realize cross-device projection in the local area network. Sharing video content of data media is often powerless for projection scenarios with large transmission distances

Abstract

The invention discloses a screen projection playing control method and device, equipment and a medium, and the method comprises the steps: displaying a screen projection resource list which comprises a plurality of video abstracts, and the video abstracts are created according to screen projection resource information; in response to a screen projection instruction acting on any video abstract in the screen projection resource list, a screen projection application list is displayed, the list comprises a plurality of application abstracts, and each application abstract points to a second application suitable for establishing a screen projection communication link with the application; in response to a selection instruction of any application abstract in the screen projection application list, establishing a screen projection communication link of a second application corresponding to the application abstract, and pushing screen projection resource information pointed by the video abstract to the second application for loading and playing; and monitoring a resource push event of the second application so as to establish a remote communication link with a playing terminal pointed by the resource push event. According to the method, the playing of the projection video in the local area network and the wide area network is synchronously controlled, and the limitation of a projection protocol is broken through.

Description

technical field [0001] The present application relates to the technical field of screen projection, in particular to a screen projection playback control method, and also relates to a device, device, and nonvolatile storage medium corresponding to the method. Background technique [0002] Existing screencasting is generally realized with the help of WeChat projection technology such as DLNA. The screencasting output in the terminal device can push the video data to the playback application in other terminal devices for playback through screencasting. The function of projecting the video data of one device to the screen of another device for playback to improve the playback effect of the video, and can control the playback of the screen-casting video in the receiver through the screen-casting output side, and the screen-casting is applied in public places such as shopping malls technology to realize the projection of advertising video to a larger playback terminal for playbac...
