Method for playing video through screen mirroring

Abstract

The invention relates to a method for playing a video through screen mirroring, comprising: when a sending end device opens an audio and video needing to be played, the playback progress scale is marked according to the total duration of the audio and video and the current playback position is marked; the sending end device sends the audio and video source information and playback progress scale attribute to a receiving end; a receiving end device receives the source information and the playback progress scale attribute and parses the source information to obtain an audio and video source corresponding to the source information; the receiving end device marks the same attribute scale according to the playback progress scale attribute, when the receiving end device opens the audio and video corresponding to the source information, the duration and the marked point of the audio and video are marked on the same attribute scale, and the current playback time point is calculated; and the receiving end device starts playback from the current playback time point. The method synchronizes the playback progress and operation of the sending end and the receiving end.

Description

technical field [0001] The present invention relates to video processing technology, in particular to a method and device for playing video on the same screen. Background technique [0002] In the existing same-screen sharing technology, the sending end of the multimedia device establishes a communication connection with the server of the receiving end device, and the sending end sends a request for playing video data on the same screen to the server at the receiving end, and the receiving end needs to play the video data after receiving it for decoding After that, the same screen playback will be realized. When the content to be played is a video, it needs to be synchronously sent to the display interface of the receiving device in the form of a video stream for display to achieve multi-screen interaction. However, when realizing the multi-screen interaction, when transmitting pictures and video streams, large bandwidth resources need to be occupied, and the transmission s...

Problems solved by technology

[0004] Although the above method solves the technical problem of slow transmission of video streams between multiple screens, when the receiving device passes the address information of the video and parses the corresponding audio and video under the address, it cannot analyze the playback progress of the audio and video at the sending end. It is impossible to automatically identify the playback progress of the video that needs to be on the same screen. For example, after the viewer adjusts the progress of the video on the sending end, the receiving end cannot display it synchronously. Poor, poor synchronization
