Embodiment Construction

[0043] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0044] There are two ways about USB redirection in the prior art:

[0045] Cloud desktop spice protocol USB redirection: It is equivalent to lengthening the section between the USB device driver in the USB workflow on the terminal and the USB bus driver, and adding a proxy to conceal the fact that the device is actually on the remote terminal. Th...

Abstract

The invention relates to the field of cloud computing, and provides a video image redirection method and a computer-readable storage medium, wherein the method includes: a terminal module compresses and encodes acquired image data to form streaming media, and generates RTSP services based on the streaming media. The virtual machine driver layer module pulls the streaming media in the RTSP service and outputs the streaming media. The virtual machine application layer module receives the streaming media output by the virtual machine driver layer module. The present invention compresses and codes video image data to form streaming media, and redirects them to the application layer of a virtual machine in the form of streaming media, thereby reducing the bandwidth used for image peripheral data redirection.

Description

technical field [0001] The invention relates to the field of cloud computing, in particular to a video image redirection method and a computer-readable storage medium. Background technique [0002] At present, for USB peripherals in cloud desktop products, the data that should be transmitted by the bus is usually captured, and then transferred to the host machine where the remote virtual machine is located by the network, and written into the HUB (multi-port transponder) corresponding to the virtual bus, so as to realize the device redirect. The principle is that the network cable replaces the USB bus, so that the virtual machine application thinks that the device is directly connected to the virtual machine. [0003] However, in the above method, the data has not been processed and compressed by the application layer, which occupies a large amount of bandwidth and has great limitations on the increase of the number of concurrency. SUMMARY OF THE INVENTION [0004] Aimin...
