Problems solved by technology

The inventor found that the current video processing method of the cloud desktop is generally to first decode on the virtual machine side and then transmit it to the client through compression. However, since the virtual machine cannot use the physical GPU to decode, only software can be used to decode the video, which occupies The CPU resources are large, which brings a great burden to the virtual machine and the client

Embodiment 1

[0046] see figure 1 , figure 1 It is a flow chart of the method for playing webpage video in the cloud desktop provided by the embodiment of the present invention, such as figure 1 As shown in, the playback method includes the following steps:

[0047] S101: Obtain the audio parameters of the webpage video after detecting an instruction to start the cloud desktop player.

[0048]Decoding and playback on the virtual machine side is the traditional cloud desktop video playback method. Video files are decapsulated, decoded, and played on the virtual machine. The video screen, as part of the desktop screen, is projected to the client through a certain transmission protocol. End-to-end decoding will greatly occupy CPU processing resources. The present invention acquires the audio parameters of the webpage video after monitoring the start instruction to the cloud desktop player, wherein the audio parameters may include volume, frequency and the like.

[0049] S102: Set multiple ...

Embodiment 2

[0076] see Figure 4 , Figure 4 It is a schematic structural diagram of a webpage video playback system in a cloud desktop provided by an embodiment of the present invention. like Figure 4 As shown in , the playback system 400 provided in this embodiment includes:

[0077] The audio parameter acquisition module 410 is used to obtain the audio parameters of the webpage video after monitoring the start instruction to the cloud desktop player;

[0078] The playback node determination module 420 is used to set a plurality of playback nodes according to the amplitude of the audio parameters, and obtain the picture frames of the webpage videos corresponding to the plurality of playback nodes;

[0079] The webpage video playing module 430 is configured to send a plurality of playing nodes and corresponding picture frames to the client, and play the webpage video according to the received selection information of playing nodes.

[0080] The playback system provided by the presen...

Embodiment 3

[0083] see Figure 5 , Figure 5 is a schematic diagram of a computer device according to an embodiment of the present invention. like Figure 5 As shown in , the computer device 500 includes a processor 510 , a memory 520 and a bus 530 .

[0084] The memory 520 stores machine-readable instructions executable by the processor 510. When the computer device 500 is running, the processor 510 communicates with the memory 520 through the bus 530, and the machine-readable instructions are executed by When the processor 510 executes, it can perform the above-mentioned figure 1 , figure 2 and image 3 For the steps of the method for playing webpage video in the cloud desktop in the shown method embodiment, the specific implementation may refer to the method embodiment, and details are not repeated here.

Abstract

The invention provides a method and system for playing a webpage video in a cloud desktop, and the method comprises the steps: obtaining an audio parameter of the webpage video after a starting instruction of a cloud desktop player is monitored; setting a plurality of playing nodes according to the amplitude of the audio parameter, and obtaining picture frames of a webpage video corresponding to the plurality of playing nodes; and sending the plurality of playing nodes and the corresponding picture frames to a client, and playing the webpage video according to the received selection information of the playing nodes. Therefore, the video is decoded and played according to the selection of the client to the playing node, the running space of a CPU (Central Processing Unit) can be reduced, and the playing rate of the webpage video in the cloud desktop is improved. And the playing node is determined through the audio parameter, and the webpage video is played according to the playing node, so that the problem of sound and picture desynchrony can be reduced, and the user experience is improved.

Description

technical field [0001] The invention belongs to the technical field of cloud computing, and in particular relates to a method and system for playing webpage videos in a cloud desktop. Background technique [0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] In recent years, with the expansion of application scenarios from a single CPU-dependent computing unit to multiple architectures and heterogeneous computing scenarios, virtualization and cloud migration have also been proposed for professional computing chips such as GPUs, FPGAs, and TPUs. strongly demand. Cloud desktop is to use virtual technology to virtualize various physical devices, so that the utilization rate of resources can be effectively improved, so as to save costs and improve application quality. With the support of virtualization technology, the connection between network software and hardware d...
