Method and system for improving high-definition video playing effect in virtual desktop

Abstract

The invention discloses a method and system for improving a high-definition video playing effect in a virtual desktop, and relates to the field of desktop cloud. The method comprises the following steps: installing a GPU on a computing node server running in an SPICE server, so that the SPICE server can call the GPU to perform video encoding; running the SPICE server and monitoring a connection initiated by the SPICE client; reporting, by the SPICE client, a local video decoding capability set to the SPICE server, selecting, by the SPICE server, an encoding mode and notifying the SPICE client,and separately creating, by the SPICE client and the SPICE server, an encoder and a decoder according to the encoding mode; playing a high-definition video in a virtual machine, detecting, by the SPICE server, a video playing area of the high-definition video according to the refresh rate and submitting the video playing area to the encoder, calling, by the encoder, the GPU of the SPICE server for video encoding, and sending the same to the SPICE client; and calling, by the SPICE client, the decoder for decoding, restoring the code into image for displaying. By adoption of the method and system, the load of the CPU of the SPICE server can be reduced, the occupied bandwidth can be significantly reduced, and the video playing effect can be improved.

Description

technical field [0001] The invention relates to the field of desktop cloud, in particular to a method and system for improving the effect of playing high-definition video on a virtual desktop. Background technique [0002] In the cloud computing virtual desktop environment, the smoothness of desktop operations is very important to users, especially when users play high-definition video, it will take up a lot of CPU computing resources and bandwidth, and the user experience is generally poor. For now, major cloud computing providers have certain technical bottlenecks in graphics and image applications when deploying virtual desktops, and the experience that their products bring to users is also uneven. [0003] At present, there are two common ways to improve the effect of playing high-definition video on virtual desktops: Method 1 is to redirect video resources to the SPICE client through redirection, and the SPICE client builds a player to play the video. Video, SPICE (Sim...

Problems solved by technology

[0004] However, these two methods have certain defects: the redirection method cannot adjust the video bit rate and frame rate parameters, and it is necessary to build and install multimedia redirection software on the virtual machine and locally, and there is great complexity in deployment, and there are The problem that the local window covers the window in the virtual machine

Although the transcoding method can adjust the code rate and frame rate, it does not significantly reduce the use of CPU resources, and the secondary encoding will bring about a decline in image quality
