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

Embodiment Construction

[0045] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings and embodiments. The following examples are only used to illustrate the technical solutions of the present invention more clearly, and cannot be used to limit the protection scope of the present invention.

[0046] figure 1 It is a schematic flowchart of an embodiment of a method for playing a video on the same screen according to the present invention, and the method includes:

[0047] Step 11: When the sender device opens the audio and video to be played, it marks the playback progress scale according to the total duration of the audio and video, and marks the current playback position, that is, the mark point, on the playback progress scale;

[0048] Wherein, the audio and video of the sending end device correspond to the scale unit of the playback progress scale according to its preset unit time value, and are marked above the corresponding ...

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, a communication connection is established between the sending end of the multimedia device and the server of the receiving end device, the sending end sends a request to play 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 and decoding. Then realize the same screen playback. When the content to be played is a video, it needs to be synchronously sent to the display interface of the receiving end device in the form of a video stream for display to realize multi-screen interaction. However, to realize the multi-screen interaction, when transmitting pictures and video streams, it needs to occupy a large bandwidth resource, and the transmission speed is slow and...
