Embodiment Construction

[0023] Through the following description of the embodiments, it will be more helpful for the public to understand the present invention, but the specific embodiments given by the applicant cannot and should not be regarded as limitations on the technical solutions of the present invention, any components or technical features Changes to the definition and / or formal but not substantive changes to the overall structure should be regarded as the scope of protection defined by the technical solutions of the present invention.

[0024] The defective that existing technology exists:

[0025] 1. The server is overloaded: the SPICE virtual desktop protocol uses CPU encoding, which will take up a lot of CPU resources. In addition to processing image rendering, the SPICE protocol also needs to handle input events such as keyboard and mouse on the client side. In the case of video, a large amount of CPU resources are used for encoding and decoding. The heavy CPU load will seriously affec...

Abstract

The invention discloses a cloud desktop video playing method based on a bottom virtualization technology. The method comprises the following steps: 1) establishing a proxy channel between a client and a server; 2) by the client, sending a video playing request to the proxy channel, and by the server, receiving the request, starting video playing software and opening a corresponding video file; 3) by the video playing software, obtaining video file information and transmitting the video file information to the client through the proxy channel; and 4) after the client obtains the video file information, starting local player software to play the video stream. According to the method, the video file is converted into the video stream to be directly transmitted to the client to be decoded and rendered, so that the problem of resource waste caused by repeated coding and decoding is avoided, the CPU computing power of a cloud host at a server is liberated, a decoding task is completed by a relatively idle client terminal, the video playing smoothness of a cloud desktop is improved, and computing power resources are reasonably distributed.

Description

technical field [0001] The present invention relates to a video playing method, in particular to a cloud desktop video playing method based on underlying virtualization technology. Background technique [0002] Cloud desktops mainly rely on the underlying virtualization technology. [0003] From the perspective of the history of open source technology, in the early days, QEMU realized the function of running other systems on a machine through a pure software mode. With the continuous development of virtualization, Intel launched a CPU that supports virtualization instruction set functions, that is, VT technology. At the same time, the Linux kernel launched a KVM driver module to support hardware virtualization instructions. Through various simulation implementations, QEMU / KVM has a relatively rich simulation device, even including virtual GPU. The virtualized cloud desktop based on the above mode realizes the function of remotely displaying the image of the cloud host on t...
