[0026] Please refer to image 3 , image 3 A flow chart of the multi-screen display method for redirected video provided by the first embodiment of the present invention is shown. The multi-screen display method of redirecting video includes the following steps:

[0027] Step S101, acquiring the first video data sent by the server and the real-time playback position of the virtual machine player.

[0028] In the embodiment of the present invention, the first video data may be the video data currently sent by the server 10 to the client 20 and about to be decoded, rendered and displayed on the client 20, which includes separated video frame data and audio frame data. During the process of video redirection, the server 10 will monitor the location information of the virtual machine player 11 in real time, and transmit the real-time location information to the client 20, so that the client 20 can determine the playing of the first video data based on the real-time location info...

Abstract

Embodiments of the invention relate to the technical field of cloud computing, and provide a multi-screen display method and device for redirecting a video. When it is determined that a real-time playposition of a virtual play is beyond a display range of a current physical display corresponding to a video play, that is, a video redirecting window is changed in another physical display, first video data in a video cache area is put in a temporary cache area at first, then a video play framework of a client is restarted proactively, so that the video redirecting window of the client is rapidlyswitched to a target play position of a target physical display, after restart is completed, first video data in the temporary cache area is played at first, so that video and audio freezing in the prior art is prevented, and the user experience is improved effectively.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of cloud computing, and in particular, to a multi-screen display method and device for redirecting video. Background technique [0002] In the current era of cloud computing, the application scenarios of VDI (Virtual Desktop Infrastructure, virtual desktop infrastructure) are becoming more and more extensive. VDI mainly relies on virtual machines divided by Hypervisor on physical servers, and the video and image processing capabilities in virtual machines are very expensive. Therefore, video redirection technology is usually used to transfer the original audio and video data to be decoded and processed in the virtual machine to the client, and the decoding, rendering and display are completed on the client. At present, the common video redirection applications on the market basically update the position of the client’s playback window in real time based on the location information of th...
